Hi Adam, have they been tested on a RHD car? How do you know they fit? Steering rack is on the other side of the car in a RHD...
Just curious - im very interested. Look forward to the dyno charts, hopefully it doesnt change the power/torque curve. I've had an audi 1.8 turbo motor with a 3" DP and it lost ALOT of bottom end torque... Was horrible. There was also this awful shudder in it...
