Reply to "STEERING DRIFT ON LEVEL ROAD"

I have a feeling that the issue here is lack of sufficient caster. These cars were originally designed for skinny tires. A 185 front, later changed to a c60.

Front caster is what gives high speed stability. The car is already maxed out for those little tires.

Every time that you increase the size of the tire contact cross patch, you need to increase the caster. The cars that have been converted to GT4 specs will show it most.

Many owners like Johnny Woods realized this and have modified the front suspension to gain more caster. There is a trade off to this though. The more caster you dial in the heavier the steering will become. On a car without power steering it will become an issue eventually.

Ever wonder how they can get the Indy cars to be so stable that they can kiss the wall at 250 and keep going? A lot of caster.
