I have a 93 wrx, bought some ohlins coilovers for it about a month ago. Problem is the N/S front makes a hell of a bang every hole i hit (big or small) sounds like i've hit the biggest pot hole in the world over every bump! i've set all shocks on soft aswell others are fine just the N/s front.
Any help please would be good. Thanks.

Coilovers were 2nd hand by the way.

If someone has a contact number for ohlins that would be great
