Bertini GT25 - Z3 based kitcar
 
Hi,
I'm in the process of developing a body change kit for the BMW Z3. I am making good progress on the front end and I am slowly getting there with the rear. We are currently working on getting the plug design right. I will try and post a few progress pictures.

I'm hoping for a completed car by the end of the summer and an official launch and a few kits for sale at next years Stoneleigh show.

I have tried to capture and combine elements of the;
Muscle of the AC Cobra
Lines of the E-type
Presence of the 250 GTO
and modern feel of the XK180 and Eagle Speedster
With a little bit of Maserati and Aston Martin thrown in for good measure.

I'm not trying to create a replica car. It's intended to be a modern car with a modern design taking classic inspiration.
It will fit all the Z3 cars. Normal, widebody, Z3M roadster etc.... I can't wait to get it finished.

I have a Facebook page that I update regularly and will be posting build updates.
https://www.facebook.com/BertiniGT25

I hope some of you like it :-)

*** UPDATE The following pictures are the first of the finished Bertini GT25 ***

I have launched the website www.BertiniGT25.com

Any pics from the side please

y cymro 23rd July 2013 22:46

This looks interesting How's the back coming on?

Anthony Cherry 24th July 2013 20:03

the back is coming along slowly - we are planning on finishing off the front first.

here is a progress picture of the front :-)

y cymro 24th July 2013 20:13

That's very pretty. If you can design a suitable back end I think you'll have a winner.
Will there be a coupe?

Anthony Cherry 24th July 2013 22:15

The back end is a little bit Z8 / etype / eagle speedster. I have a few progress shots on the Facebook site.
I want to do a coupe. It will be a fastback taking some inspiration from the corvette C2 / etype fastback.
But I need to sell a few kits to make my money back before I go for the coupe. I need to know there is a market for what I'm doing. :-)

y cymro 24th July 2013 23:16

The side view on facebook looks good. It would be good to put the same photo here if you want to gauge reaction.
Whether or not it will sell depends on many things including the obviois ones like ease of fit, support provided by the seller, and of course cost. I think it should sell well based on looks alone. Seeing the side view I think you're right to focus on a soft top - it suits it well.
I've paid a deposit to Chris at Tribute Automitive for something special that I'm really looking forward to. Otherwise I would be very interested to see how yours turns out.
Best of luck.

Anthony Cherry 25th July 2013 08:41

i hope to do a full build DVD - including how to strip the Z3, where to bolt the panels and bonding proceedure. Plus electrics.

However it should be pretty much the most simple build ever! One piece rear section simply bolts on to the car replaceing the existing wings at the same points.

The bonnet / boot are bonded onto the cars existing bonnet/boot frame after taking the skin off. So all the hinges and catches remain in place!

I hope it could be a DIY build for 2 people in a weekend.

We will have to see :-)

y cymro 25th July 2013 13:48

That's a very ambitious plan and I wish you all the best. The bolt on panel swap idea sounds very exciting and will give customers the chance to change shapes when you introduce more models. People could buy a modern theme and a 60s theme for example (or softtop and coupe) and swap them over as it suits them. A modern one to visit the British GP and fit the retro shape for the Goodwood Revival!
Good luck.

An Alfa theme would be nice:

And give me a shout if you decide to make one looking like an 8C ;-)

Anthony Cherry 31st July 2013 13:05

the back im designing is not a million miles away from the rear from that car on ebay.


:-)

y cymro 31st July 2013 19:40

I agree, yours is a damn good effort.
Now, about that 8C front.........

merks 2nd August 2013 13:44

Damn that's a really nice job you've done there man

Anthony Cherry 5th August 2013 17:10

i have just picked up the wheels!

they are BBS 18" split rims - with an anthracite centre and silver barrel.

Very nice. They'll really suit the shape

Anthony Cherry 14th August 2013 15:16

i have just finished the Bertini GT25 Website. Its got lots of the progress pictures on it and i intend on keeping it up to date.

Anthony Cherry 17th August 2013 11:41

Just finished the mould for the front end.
It should be good for about 200 bonnets :-)

Anthony Cherry 24th August 2013 09:26

A sneak preview news article featuring the Bertini GT25 has just been published in Complete Kit Car magazine. The words have been blurred by request of the editors. But they said nice things :-)

http://i1214.photobucket.com/albums/...f0f6423989.jpg

Anthony Cherry 4th September 2013 18:40

There have been a few developments:
Firstly there is another article - this time in TKC magazine (Total Kit Car). This one is an online article - but they want to do a print feature when its finished :-)
here is the link to the online article:

http://www.totalkitcar.com/2013/08/29/italian-exotica/

Kit development wise the first moulding is out of the mould and the underskin is being developed and fixed to allow easy installation of lights and grills + easy fitment of the bonnet to the existing hinges.
i have my Z3 back from the local BMW specialists DM WORX - i have had Bilstein Shocks, Eibach Springs and poly bushes fitted. Plus many worn suspension parts replaced.
Also had the wheels fitted balanced and tracking adjusted - it now sits 30mm lower and you can really notice the difference in the cornering.

Here is a picture of the new wheels fitted to my Z3.

WorldClassAccident 6th September 2013 09:15

I like your idea, it is the same idea I had!

We have taken slightly different approaches as I have no skills in making the molds or styling the body I approached Chris at Tribute to do mine for me.

I won't post pictures here as I don't want to spoil your thread but if you look over on the Tribute forum you should find the WCA build thread easily enough.

Your front end looks great, a modern interpretation of the classic style. Mine is also an interpretation rather than a replica but more period in style.

I will watch this thread with interest. Lots of pictures please, side shots and rear 3/4s when they are ready please.

Good Luck

PS If you want some front or rear wings that have only had one set of splash molds taken from them then PM me. Still in good shape but with some gloop still attached

Anthony Cherry 17th September 2013 16:01

im loving your work WorldClassAccident!... great minds think alike :-)

im going to be putting some more pictures up at the end of the week. hopefully with the grills fitted to the front end of the actual moulding.

are you planning on selling your car in a kit? or having tribute sell it? will it be finished for stoneleigh next year?

Anthony Cherry 23rd September 2013 17:16

Here is a flavour of what the front will look like with the grills fitted.

Oops. Posted the image thumb. This should be a bit bigger.

I have just got the badge that I designed back from the manufacturers in China. I'm really happy with the quality :-)

http://i1214.photobucket.com/albums/...ebed8dddb4.jpg

The Shadow 4th October 2013 16:59

I like that a lot , the front looks great . Did you start with an existing bonnet or is that all hand created ? The curves are fantastic.

Anthony Cherry 4th October 2013 22:32

To make the plug for the mould it actually took 4 different bonnet/bumpers. And a lot of filler and hand craft.
Before the crafting took place the bonnet looked like a jigsaw of different components from different cars.

Thanks did the kind words. I hope to have a finished car for stoneleigh 2014. :-)

Anthony Cherry 17th October 2013 12:38

Here is the latest update of the work that's going on the rear.

redratbike 17th October 2013 14:04

nice!

just noticed the number plate? whats the deal there?

Anthony Cherry 17th October 2013 14:17

It's an Australian number plate. I'm trying to get the apature to fit UK, USA and Aussie plates. Also the southafrican ones and motorbike plates should fit in a treat.

Anthony Cherry 17th October 2013 14:19

I'm based in the UK. In Buckinghamshire.

oorward thinking that regarding other markets and numberplate sizes

ha ha i amended my question after i saw you are in aylesbury...

are there going to any vents in the rear wings at the back?

DSG4ME 21st October 2013 07:56

Hi there,

I have been following your Bertini GT project since I first read about it several months ago and I am really impressed with what I have seen so far.

I designed something similar (a BMW/250 GTO/Lyonheart K mix) some time ago but it never got past the Photoshopped vision I had, but you have gone further and are building your dream car which is really great. One of the things which I like about the Bertini is that its a mixture of many other great cars without it been a direct replica of anything. That Jaguar concept inspired front end really looks the part and that rear end is progressing nicely, although slightly different to what I imagined at first. I thought the lower rear bumper/exhaust section would resemble the Lyonheart K. (another fantastic car). Even so, its still looks great.

One thing which I´m not too keen on are the rear lights units. You mention on your FB page that they are Porsche 996 units cut in half. If you are planning to sell kits outside the UK (I´m sure you will have many clients) you may find that cut-up or modified light units are illegal in some countries. Its always better to use unmodified light units as this has the advantage that if they get damaged the owner can always get a new light unit off-the-shelf. Have you thought of using the latest 2013 Porsche 911 LED lights or the Lancia Thesis LED units ? They probably cost a bit more but they would look awesome, and a car like the Bertini should have the best. I think you also mentioned somewhere that the front headlights are Fiat 500 units ? Here the ultimate would be these same Fiat units with the DRL,s and Angel Eyes (as seen on Ebay).

Will you be having any optional extras such as bonnet or front side vents ? Maybe in the future you could also offer a Coupé style hardtop (something similar to the Zeintec Porsche Boxter hardtop) so owners could have a coupé in the winter and a convertible for the summer.

I just can´t wait to see the finished car, its going to look stunning. I hope you put lots of pictures up on your website and if possible some videos so that all of us that live outside the UK and won't be able to see the car at a car show can get an idea of how it will be.

If everything goes as planned I´m sure you have got a winner there and you will sell many kits in, and outside the UK.

Best of luck. :-)

Anthony Cherry 26th October 2013 11:58

Thanks for your comments I was planning on having the Alfa GT rear lights for the project however they didn't look as good as the 911 lights cut down when actually in the back of the car.
The new 911 and 997 real lights are slightly the wrong shape and I'm hoping if things really take off to get the rear lights custom made and manufactured by companies such as hella.
The cutdown 911 the lights do not actually cuts through any light clusters merely the lens which connects them so the light clusters operate perfectly as they would before. there is no modification to the reflection or beam direction. all that is being removed is the top section of indicator and the indicator can be remounted.
Regarding the coupe and hardtop it's something that I've definitely got planned for the future I wish to have a coupe version of the car made in the year following its launch and also intend to try and manufacture a hard top for the convertibles with a fastback style.
I imagine that a lot of people who buy the kits will want to do certain modifications for themselves such as bonnet vents and vents behind the rear wheels. They may also have ideas regarding position and placement of exhaust pipes. With this in mind the rear diffuser will have no cutouts done for exhaust pipes as in the picture above.

I really can't wait to get the project finished so I can get a video and promotional pictures made :-)

y cymro 26th October 2013 13:42

I think those lights look very good. The back end reminds me of the Jag F type. How would lights from that fit the style, I wonder.

DSG4ME 27th October 2013 12:25

The F type lights don,t look too bad but personally I think they make the Bertini look too Jaguar-ish !

Here is a selection of different light set-ups. Take your pick, although if Mr. Cherry is going to have some custom made units for the car they will probably look awesome.

Anthony Cherry 27th October 2013 16:55

I'm loving the enthusiasm, I have tried a number of those lights already and unfortunately some of them are just too big. The Laguna Coupe lights are far too big for the back and meet almost in the middle. I initially really liked them but it just didn't work :-(

I like the Ftype ones. But they are pretty recognisable, expensive and do make the back look like a fake FType. (Not a bad thing at all!!! But not quite what I'm after).

There are also additional considerations such as the number of different lights in the rear cluster many of them are lacking things like indicators, reverse lights, reflectors, brake lights and taillights and some just have a combination of a few of them. which means you need to find additional lights which can make the back look untidy. this is the main reason I went to the porsche lights as they have majority of the bases covered. The latest 911 lights unfortunately have to be at a certain angle therefore it disrupts the lines as they are slightly upswept.

After trying the Laguna lights I then tried the alpha GT lights but these lack rear fog lights and reversing lights and they also lack reflectors so in essence they're really just a tail break and indicator which means I have to find three additional lights in the back this is what I scrapped that idea and went with the Porsche 996 ones.

I have not seen the lancia lights before so will look into them for a possible future revision.
