These things suffer from broken spot welds and iffy diff mounting as standard so do you really want to chopping out a strengthening panel?

Thanks for the feedback guys, you're absolutely right about not messing with anything structural - it just looks like a carrier for the plastic trim to me though and I'd love to get rid of it.

Guess I'll have to wander into my local Beemer dealer and ask the man in the oily overalls with a hand-rolled fag hanging out the corner of his mouth for a definitive answer...

I know they were built Stateside, but are they really that bad?

Anyone know if the diff issue is linked to the power output of the engine - are the bigger motors overpowered? If so, all the more reason to stick with a 1.9.

OK, found my own answer regarding the diff here -

http://www.bimmerforums.com/forum/sh...-mount-failure

Looks like the monocoque was only ever meant to take a lightweight 140hp motor and anything bigger can stress the structure to the point of catastrophic failure.

But hey, at least you can boast to the other patients in A&E that your car was going 150mph when the back wheels came off...

From what I have read on the forums it was only really the Z3Ms that ripped their own arses off

The other, even the 2.8, are more about firm but gentle acceleration rather than screaming, neck snapping thrust

I read that only z3ms are affected too. The extra 100 odd horse power and traditional LSD will do that! (The Torsen diff in the 2.8 seems less harsh in action to me compared with the clutch type used in M cars)

Anyone with a Z3 should change the diff oil occasionally. BMW called it lifetime oil but it isn't. I changed mine in about 15 minutes and it came out like drinking chocolate. A lot smoother and quieter since the new oil went in.

Instructions
The diff has 2 plugs at the back. Remove the spare of you have one to see them more easily.
Loosen the top one slightly to make sure you can. You don't want to drain the diff and find you can't undo the fill plug.
Remove the lower plug and let the oil drain fully.
Put the bottom plug back in and remove the top plug.
With the car level, fill the diff until it just starts to dribble out.
Refit the top plug and drive away happy

That's good advice. As much as I like drinking chocolate it isn't a good lubricant

As much as I like 75W/90 oil it isn't a good bedtime drink.

The world is better when everything's in the right place

WorldClassAccident · #91 15th March 2015, 21:44

I put 75W/140 in to replace it. each to their own

Tribute Automotive · #92 20th March 2015, 20:45

Inner support panels bonded to inside of front end body section

Channels for front lights wiring boned in

GRP latch plate with steel inserts and captive nuts to accept standard BMW Z3 bonnet latches

Rollcage brackets bolted to Z3 softtop fixing points in windscreen head rail

GRP insert bonded top of windscreen head rail to join to new rear body section

New alloy insert bonded into Z3 petrol tank neck....

.... before new flexible pipe was installed

Headlights, front indicators and side marker installed and wired. I really like Bob's chioce for side markers

Tribute Automotive · #93 20th March 2015, 20:57

Rollcage drops into existing Z3 roll hop uprghts...

...and bolts down at rear to inner wings above Z3 rear lights

Rear inner mounting panel test fitted

Looking great, a spectacular effort, well worth the wait.

Mister Towed · #96 21st March 2015, 08:42

That's looking soooo good.

Few questions though:

Will the bonnets for diy customers come fully built up with inner panels, hinge points and wiring guides?

Could you take some pics inside the car so I can see the relationship 'twixt roof and roll hoop please (want to plan for a headliner).

Is that fan in the boot part of the active 'ground effect' aerodynamics package?

It is looking bloody good though, did I mention that already?

Jonno · #97 21st March 2015, 08:48

Great work, looks like you've done everything you can to make the builders life easier

GazDavies · #98 21st March 2015, 08:52

Wow, it gets better every time I see it and looks like a top quality kit with some well thought out details. Well done guys!

I have spotted a few things that are making me rethink my quick and simple build plans though. Thats not necessarily a bad thing, just requires a different picture in my head.

Tell us Gaz.

Tell us of these things you have spotted of which you speak, and of the picture you have in your head.

Don't keep ideas to yourself, we're all ears.

Paul L · #**100** 21st March 2015, 11:49

So if I've picked up the right dates, we have...

Donor Car Arrived - 9th March 2015

Donor Car Stripped - 12th March 2015

SWB 250 - Under Construction - 20th March 2015

Simply outstanding.

Note:
This build is actually closer to completion after just 2 weeks, than my build is after almost 3 years!

All the clever thinking that has gone into the design/construction will save any builder time and stress, so it is worth every penny.

I really hope this kit is the HUGE success it deserves to be, good luck, Paul.
