The 2 and 3 hole caster blocks have the same geometry, but the 3 hole versions are a slightly softer material and have the hinge pin hole molded, where the 2 hole FT caster blocks are drilled. The 2-hole blocks are shot in the super-stiff carbon material, so some racers notice a handling difference due to flex. The drilled blocks are also succeptible to shifting in the fixture and not being identical left/right...so I run the molded caster blocks which are the same every time they're made.

What does this all mean to how the car handles ?
Three hole has smoother or less steering compared to the two hole ....*
*Comparing both with the steering block installed in the middle of the caster block...
So ? If you ran the three hole block .030 lower , it would be the same as a 2 hole in the middle ....
