Hi guys.

I have recently put the car back together after the 2.7 had a big end bearing failure and stood for a few months. The engine now has the Metric Mechanic 3200 Rally bottom end.

Here are some videos of a recent trackday.

This is some footage from Race 1 of the BMW Racing League. I was behind a E30 DTM M3 look alike with a 2.9 M20 stroker + carbs.

The last few laps from race 2.

Another video of me following a 325is (2.7L) Turbo. Unfortunately both he and his passenger had issues with their clothing (no long sleeves, no gloves) and by the time they had it sorted out, there was only time for one lap before the session ended.

A video of me following an E92 M3 on road tyres. The cornering capability of the M3 is mind blowing, especially in high speed sweeps. I don't know if you'll be able to see it on the watered down, YouTube converted video, but the M3's front wheels are steering madly left and right through some turns and I can only imagine the fun sawing at the steering wheel.

Finally, here are my efforts trying to pass the mighty E60 V10 M5 (semi slicks).

you could build it to the larger side... the diffuser would not reach the smaller tub.

theres a lot under the car to work around, and unless you made the rest of the car 'smooth' it wouldnt work too effectivly.

[Andreas]

why dont you cut up into the rear valence to create a deeper diffuser? make the top of the diffuser the bottom of the trunk... if you follow me. the sides would the inside edges of the tubs on either side of the trunk.

I hardly managed to finish the closure in time for the race. It is actually not easy to mount something straight since there is very little symmetry on the body - the fact that the rear is a little bent on one side didn't help either.

I do understand what you are saying and wanted to do that but time was against me. One thing however also held me back from implementing that solution - the tubs on either side of the trunk extend by different amounts towards the middle of the car which would result in an odd looking off-center diffuser.

Here is a split screen comparison video of my co-driver's best lap in the race vs my best lap from the 2 Hour Enduro.

Awesome. Can you post some pictures of your pedal box installed? And did you patch up that spare tire hole? I might have missed that. Do you have any more pictures of that?

Here are some pics of what you've requested.

hey, saw the vid of the accident. Glad it happened there and not anywhere else like you said. scary stuff

I love the build and this is a great thread.


I wanted to gain info on your brake and suspension setup... Those look like massives but I wouldnt know.

Thanks.

No the brakes are not from Massive. It is a custom AP Racing setup for the front. 330mm x 28mm full floating discs with 4 piston AP Racing calipers and Performance Friction brake pads.

The rear consists of E46 M3 328mm rear discs and E46 M3 rear brake calipers with the standard brake pads for that car.



I've dumped the brake booster and installed a Tilton pedal box. Both the front and the rear calipers have their own AP Racing master cylinder and the clutch uses a Tilton master cylinder.

I did hear a rumour that BMW spent millions developing a special aluminium alloy for their fuel tanks that gives off brown rust like I found in my fuel pump and fuel filter ;)

Considering your heavy S54 engine and gearbox combo, you will battle to achieve that 999 kg goal.

S54?

[SA E30]

Oh! Now I thought that brown substance was your secret fuel additive? :P

[Andreas]

That e30 has a 60lt Ally tank though. None the less.
