Grip Patch for GP4?

I've been trying to simulate seasons on GP4 with various teams, but have run into the problem in being much faster than team-mates etc. After a bit of a search I came across the BHP/Grip patch for GP3 and GP3-2000, but have been unable to find one that works with GP4, despite numerous topic on this site stating that they have used one. I tried using the GP3 version on GP4 but it didn't work (which was to be expected).

If someone could point me in the direction of the GP4 version I would be very happy :D

you can modify the grip using gp tweaker but i think its really unreal .. the better way to solve your problem is changng the drivers performance values. Set higher numbers and you gonna see a bunch of aces drivers around.!
