BMW E92 M3 GT4

LesiU · 12-29-2010, 10:08 AM

Hello guys!

I'm one of SimRacingPL community administrators. I'm working on physics for rFactor simulation (for PC) on some road going and GT4 class cars. One of them is of course M3 E90/92

I already collected some valuable information about both stock and racing version of the car, but still there are things which I won't find in the brochure or at BMW website... that's why I came with such post.

I'm looking for people who had/have access to GT4 class car and could provide me some additional information (and also how the car is doing on the racetrack).

Additionaly, I'm looking for M3 E92 road car owners, that could provide me that information:
- more info about stock dampers (travel and damping characteristics)
- brake booster ratio (you know, something like 3.0:1)
- brake pedal ratio (length of the whole pedal, divided by length to master cylinder mouning on the pedal).
- ground clearence at front and rear axle
- differential preload (power and coast locking is variable from what I know)

Thanks in advance!

Oh, yeah, I might forgot to say... 2 left :P

Oh guys, come on! Someone with M3 E9x in his garage could at least measure brake pedal ratio for me

Czesc Lesiu. Good luck with your quest. Please also try contacting Turner Motorsports and / or Bimmerworld. They both have extensive experience racing these cars and for example may have had time to dyno the original shocks, etc.

Will try to catch them

Pozdrowienia z Polski!
