I notice at 200+ my car start lifting as well, it's a common issue with many cars. As a note, I too can hit just over 200 on the back straight at Mosport in the dry, 280 is nuts though.
Actually the car is planted to the ground, it's just that under full breaking that the back end seems to be light.

All BMWs are light in the back under braking. Splitter/rear wing will help, but the weight will always transfer to the front under braking. The only way to remedy this is through engine breaking. However, at that speed you can't drop into 4th(dropping a gear will cause the rear end of the car to slam down due to the powertrain trying to slow the rear wheels down). Bottom line is the E36 M3 is not aerodynamically or mechanically setup to run at 250kms + and brake hard "safely". If you want to do these things safely without any of the problems your experiencing, sell your M3 and buy a 911 TT or a ferrari / lambo.

What about a brake controller? You can transfer the braking force to the rear wheels on the track and back to normal for everyday driving.

How about get some stiffer springs at the front?
I hit about 215kph in my track car, and it's only 2700lbs, with engine mods. Cobra Mustangs hit about 230kph. I doubt a basically stock motor M3 with >3000lbs will hit 200kph easily. However, I do agree that the car will get a bit light under heavy braking. A wing will help, but not much ... what you want the wing for is stability through high speed conrners (like trun 8)

Nope ... the issue is not braking, it's weight transfer. Doing that will just lock you rear wheels (or kick in ABS).

Its strange how some e36's react at 200 KM/h. mine sees 200 every blue moon, and behaves rather well. (litterally, just 200, rev limiter prevents me from going much faster). It seems well planted, and handles well enough. My cousin's 325i (94), get VERY ratty at 130 MPH (he's in the states). His car is very well maintained, everthing is straight and aligned. he's on coilovers, im on stock.


DarknessM3, if you want to borrow my GPS setup sometime and get a more accurate read of your top speed, just ask

The only reason the car WOULDN'T be stable is if something is off, wheels are off balance, bad baljoints, etc.

And correct me if i'm wrong, but doesn't Darkness' M3 have a SC on it? He should have NO PROBLEM going faster than 230 on the straight if a stock M can do 215!

Yes I do have a supercharger. The reason I got one is for the track, turbo produces to much heat for my taste.
