£350!!! hahahahhahahahahhahahahah! Thats a joke... right?
I had my cupra solid front/rear's, top mounts, surface bearings, rear bump stops cut down, and a v-maxx suspension kit fitted for £100. Then i had my ball joints and ARB bushes fitted for £70. The ball joints involve a fair bit of work from what i can tell, but the ARB bushes are pretty straight forward.
