Sorry for the Lazarus post, but is the problem head bounce or suspension bounce? I f the latter, this is from an old nogrip thread about the '88 F1 mod, may be useful:
"Smother suspension for formula 1 - 1988
------------------------------------------
Go to your GTR 2 folder .... Game Data/Teams/Formula1_1988/Grid/Mclaren...
Then open the ''HDV'' file with Note Pad and scroll down the page until you see the section called..... ''[FRONTLEFT]''
edit and save these 2 lines as follows..
BumpTravel=-0.025
SpringRange=(68000.0, 2000.0, 106)
do this with all 4 wheels = [FRONTLEFT] ' [FRONTRIGHT] ' [REARLEFT] & [REARRIGHT]
thats it ...your done ..!
Now the car will drive a lot smother (not bumpy)...
do this with all or as meny teams as you wish ..
this is only a solution (& not a fix) that meny people are using to sort the problems with the over bumpy suspension......enjoy
----i'm not sure about the online capability if you edit this file....????
try it and find out?----
