Yellow car with Black roof
 
Chris

Black roof down to top of rear wings and across below rear window,
think back to your youth and black vinyl roofs.

My old Tvr 3000m was finished off that way.

:peep:

Paul L 25th February 2015 14:33

Very Andy - Just to echo the words of Chris @ Tribute & Mister Towed...

I started my build "next door" with no experience of working with fibreglass what so ever.

Yet even I was able to make some useless doors "disappear" & build a new scuttle from scratch.
( With apologies to Geoff & Chris for adding more Sammio photos to this thread. )

https://lh5.googleusercontent.com/-H...o/DSCF3780.JPG

https://lh3.googleusercontent.com/-n...o/DSCF3791.JPG

So moving / changing / replacing a side vent should be a piece of cake.

However if you want to see just what is possible when people like Chris & Dan get to work...

Have a look in the "Links to useful info" thread at the top of this section of the forum.

Then click on the links to the development threads for the A352, Kobra, or Z300s.

I am always amazed at how they cut things up and join them back together. :cool:

I also think the 250 SWB will be a very straight forward kit to build, even if you want to modify it a bit.

Cheers, Paul. :)

Neil i am not a big fan of buildersfoam between panels,i am worried the foam will hold moisture in.........
i asked about the space between the panels as i have no expirience with grp over metal and don't know how much space is left between the panels,my knowledge of hollow spaces is that they could work as sound chambers.
In my hotrod i have made a wooden rear benchseat,before i fitted a kind of dynamat on the floor under the seat there was a lot of more noise as when i drove with no seat or dynamat before.
It would be a bummer if the car is finished with buzzing doors:shocked:

Scottie22 25th February 2015 16:31

Once the foam has cured Rene, I believe it is waterproof, and water resistant, so if you start with a dry cavity, (all metal rust proofed and painted) you should be okay.
Buzzing bodywork would be a pain, but you could always drill a hole and foam it afterwards.

WorldClassAccident 25th February 2015 17:45

Check out some of the 3M foams. They are much better as they stay soft and are designed for use in automobiles

Mister Towed 25th February 2015 18:24

Just a thought, can the body be supplied or adapted to fit any Z3 donor, or does it have to be the wide-body model?

Mister Towed as far as I understand it what makes a wide-body Z3 are the various panels that are bolted onto the structure and therefore once unbolted there would be no difference , Geoff .

Thanks Geoff, that makes sense. Also just found this site that suggests the track width is the same regardless of engine size -

scimjim 25th February 2015 19:05

I'm no eggspurt but I thought that pre 99 the 2.8 was wider than the 1.9 (bodywork and track) which had shorter driveshafts?

Kit 275GTB 25th February 2015 20:26

From the Owner's Handbook:
Front/rear track: 1.8 = 1411/1492; 2.0,2.8 = 1413,1494 and all are given the same width of 1740.
The 1.8 engine size gives a range of about 7 tyre widths on 15", 16" or 17" wheels front and rear on 7, 7.5, 8 and 8.5J rims and 225/45 ZR 17 on 7.5J front and 245/40 ZR 17 on 8.5J rims rear. The 2.0 has almost the same range but the 2.8 only gives 225/50 ZR16 and 225/50 R16 or 225/45 ZR17 and 245/40 ZR17 rear.
These differences might account for 10mm in the rear track but I suspect the term "wide body" referred to the styling changes which took place. Does anybody know better?

They only difference in Z3 body shells is around to boot area. The Facelift cars have a larger boot opening where the lid latches. It only affects the rear internal fitting panel of the Kobra and SWB kits, we can supply either panel, just let us know the age of your Z3.

scimjim 25th February 2015 22:34

I drove a 1.9 and 2.8 back to back many years ago and found the one underpowered and the latter too powerful for the chassis (in stark contrast to the 3 litre z4 I test drove around the same track a few years later!) so it would have to be a 2.8 with a full cage to stiffen the chassis for me.

Thanks for your input everyone, and thanks for clearing it up Chris. It's good to know that you've covered the bases for any donor Z3.

I'm hoping to find a 2 litre six pot donor as it will sound good, go well enough and be legal on H speed rated tyres. The 2.2 litre cars and above must have at least V rated tyres, which narrows the availability too much for my liking.

If the right car at the right price came along I'd still look at a 1.8 or 1.9 though. Alloy flywheels are available stateside (I'd be fitting a new clutch as a matter of course anyway), which apparently transform the M44 motor.

Cue WCA for a rant about 1.9's...

I'm a little disappointed ;-)

y cymro 26th February 2015 15:02

I think I'm right in saying that all 6 cylinder cars and all facelift cars have a wide rear track, whilst pre-facelift 4 cylinder and z3m had a narrow rear track so that wider spacers will be required in the latter types unless you use wheels with z3m dimensions to fill the arches.

Kit 275GTB 26th February 2015 15:34

Wide body?
 
Wikipedia says "Width 1996-98: 66.6 in (1,692 mm) 1999-2002: 68.5 in (1,740 mm)" but no figures for the track. My handbook is dated (c) 1999 so perhaps it does not have data for the older (narrow body) cars?

jones 26th February 2015 17:06

I can't confirm but I am sure the rear wheel arches were I thought wider as the side skirts are different depending on model. These are bolt on bolt off wings so can you not remove it as part of the build regardless? aka Bertini boys style

Hi Rob. Here are the main sections of your first SWB kit, smaller panels ready tomorrow:

Chris and I am guessing Dan, these look absolutely fantastic. If/when I finish the MX250 I am definitely doing one of these!

Well done!

mobilerobbie 27th February 2015 08:48

chris, all followers must conclude now that you are doing an amazing job!!!!
Look forward to collecting the 3 kits next week.

My staff cannot wait to get their hands on the kits, the rolling chassis are all waiting!!

Z3 track dimensions
 
From 3 independent sources, the rear track of early Z3 models is between 1427 and 1439mm / 56.7’’. Later cars have a rear track of 1494mm / 58.8’’. An increase of between 55 and 67mm. The front track ranges from 1411 – 1423mm / 56’’

May we agree that rear track is measured between the centre lines of the rear tyres. Therefore tyre size will make little difference. Wheel offset or the use of spacers can make a difference.

The Z3 diff mounting frame or rear axle carrier, also carries the trailing arms. The frame is the same for early and late cars according to the reliable OEM website – the part number is the same. The trailing arms have different part numbers. It is unlikely that the hubs / drive flanges would be changed so much as to accommodate a 30mm increase each side, so the most likely place for the increase in track of about 60mm, appears to be the trailing arms.

Could we press bm dealers to have a UK OEM site ?

Alternative explanations are welcome.

scimjim 27th February 2015 15:27

it's not "early" models - it's pre 99 1.9 litre cars (the 2.8 was already "widebody"). If the trailing arm is wider, the driveshafts are almost certainly longer too.

That's one cool looking body, had a quick look on tributes web site but no info, does any body have an idea of the cost for the shell?

Mister Towed 28th February 2015 08:19

Ooh, as a former Sammio builder I'm not sure my brain can quite take in the quality of those internal supporting structures. That's not meant to be a criticism of the Sammio product (it was incredible value for money and I'm probably its second biggest fan after Phil J), but until it was bonded onto the frame and had the internal cockpit panels fitted, the shell had all the structural rigidity of a blancmange on a hot day.

These mouldings are starting to look very good indeed and I reckon the kit will be excellent vfm for the price quoted. Keep up the good work!

Tribute Automotive 28th February 2015 19:55

Pictures of a complete set of production GRP panels, with the exception the grill and surround which are the prototype units, correct grille along with steel side window frames/glass and roll cage/shell brace will follow next week:

Paul L 28th February 2015 20:45

Chris & Dan - You must feel like proud fathers. :cool:

You have a lot of nice kits in your range, but this is my favourite by far.

Does this mean you can approach Stoneleigh with "just" a paint job to do?

( As opposed to your usual frantic build a new kit in a few weeks approach. :icon_wink: )

Everything looks so good and well made I hope the 250 SWB is a big hit.

Good luck, Paul. :)

hurnleft 1st March 2015 02:48

It all looks brilliant Chris.
I'll speak to you in the week and am all sorted for drop off on the 9th.

Cheers, Bob.

This all looks really great IMHO, I especially like the attention to quality with the coremat in the panels. One question- is it still possible to remove the windscreen once the kit is in place?

Yes, see pictures in post 811. You can see a before and after fitting of the rear section complete with front screen pillars.

Thanks - I think my colour-deficient vision didn't help, but I can see the new just exactly the same size as old. Getting better all the time! Now all I need is to shift 2 projects to get cash and space.

Tribute Automotive 1st March 2015 22:25

Glad to hear that everyone is shifting all their old projects/cars to replace with SWB's. I am looking forward to seeing a few at Stoneleigh.

Paint Paul? A rare sight for us at a show. :bolt:

Very Andy 2nd March 2015 10:25

Oh my word how fantastic do those panels look!
Great job Chris.
This one could outsell any of the cobra replicas IMO.
You are on to a winner for sure. Stunning. Cant wait to see one finished.
So, what colour is the show car going to be? My choice would be silver.
