I like the car from the outside.
In my opinion, the car needs to be updated from the inside, to fit more being a racecar.
But for sure, its a matter of money, and specially time to build something big up.

I am also in Brisbane. I just bought a red 1990 318is. Just wondering who you got the BC Racing coilovers from and how you came it those spring rates? Mine will be a road car only though (race car is an MX5). Also, how much guard rolling was required to fit 0 offset? Nice shot at Cootha Classic BTW....this year or last?

This is a great pic.  As an old former Brisbanite, I recall with fondness many a drive around Mt Cootha!

I'm also curious as to what size R888's they are.

thats the link to the coilovers, i got 8/10 because i spoke to simon at rx automotive. the bc racing coilovers are great for track/road use. u can change the damper so its nice and soft or really firm. the tyres are 225/50 r15. there was a fair bit of rolling/hammer use to get them to fit.
if u have any more questions just ask

A little more info on the flywheel?

Cool ride.

i bought the flywheel through bmp design. its actually a aasco motorsport flywheel. made a massive difference.

DUDE!  I have been told time and time again that there was no aluminum flywheel for the M42.  That is the same price I paid for the one in my last 325 so it is perfect!

THANKS!!!!!!

Getting to tech on it;  I'm assuming a direct bolt in (this is not an M20 flywheel conversion)?  Also, just how bad did the vibes at idle get?  I know the M42 is a very buzzy motor, but after I put all the sound deadening in, I'm not too worried about that.

it is a direct fit. but you need to change your clutch so it has a sprung clutch disc, if you dont, it will be similar to a button clutch. i went to a clutch specialist and got him to set one up for me. its an exedy heavy duty peasure plate and organic clutch disc. as for the idle it isnt to bad when the engine warms up. but having a light weight flywheel makes the engine alot easier to stall. apart from that there arnt many cons.

Put E36 gearbox in it and it will not stall :D

OK help me out with this part a bit...  Button clutch?  Sprung clutch disc?

Good info nonetheless, thanks!

ok so all clutches in road car are design to slip when they are engaged, this means u can have a gradual, smooth engagement verus either on/off with a button clutch. to make a clutch slip there are 2 things manufactors do. they either put springs in the flywheel (dual mass) or put springs in the clutch disc. if u have a dual mass flywheel then u will have a solid clutch disc, and if u have a sprung clutch disc then u will have a solid flywheel. if u have a solid flywheel and a solid clutch disc then there wont be any slip and the clutch would resemble a button clutch. hope this help

Like lockup torque converters. If there is no give, you get 100% lockup, which would probably make for a crappy ride on the street, but all the power to the ground asap on a track only application. Also, less clutch wear? Less slip = less wear, even if it gets the crap beat out of it.

Viable on the street? or too crazy?

Post by: gtatbrissy on July 10, 2010, 09:47:30 PM

well usually u get a much more aggresive clutch plate when u get a button clutch so u would need a beafy left leg to opperate it. so if it was just a street car i would say it was a no no. for a track car it would be ideal. also button clutches are know to chew out gearboxes like no tomorrow

Right on.  I thought all this was the case, but just wanted to verify.

So is there an easy "normal" (sprung) clutch disc that is a bolt in for this setup?  I'd have to say there is due to the fact that many of these cars in Europe don't have AC and subsequently have a different, non- dual mass flywheel (which was what I was originally going to get while over here).

Thanks. Still trying to decide what to do about suspension. Is there much work required to get the BC Racing coilovers to fit?

I have decided on 16"x8" in +20 offset with 215/45/16's, so hopefully I shouldn't have to worry too much about rubbing.

Its not to bad. u do need to cut and reweld the front struts. so if u know anyone who welds its a great bonus. apart from that they are pretty easy. just make sure u measure the strut diameter before u order to make sure u get the right size, there are 2 types. i think its either 57mm or 63mm, but i could be wrong

I know this is an old thread but very keen to see at what stage this race car is at now. Cheers!
