Who else has HOP KITs?
When I put on my roush exhaust and phase 3 roush blower, I also put on a hop kit.
Who else has experience with hop kits?
I am wondering if it was worth the investment...it runs great but I have no comp.
Has anyone upgraded to the phase 3, driven the car, and added a hop-kit?
How much traction control and advantage did you notice?
