I am the same. I belive the first "go faster" mod you can do to any car is increase braking power. "But that don't make you go faster" I hear everyone cry. No, but it means you can brake later and harder, meaning you and your mates two std cars, you will win a race as you can outbrake him to win corners....
No point having 200bhp if your brakes are only good enough for 130, and no point having 200bhp if the suspension/bushes can only handle 150bhp onto the road is it?
