Well finally, after all the hassle involved, i got the call from the garage to say my car was ready - williams front track was fitted!
Pics to follow over the weekend but ive been out driving it all evening and can tell you if you have a valver, get this mod done! The difference is tremendous - stability is greater, the car rolls less - cornering speed is immense; where previously i could take one at 30, now can be taken at well over 40! Less need to brake now as the car sticks better which suits the 1.8 - revs can be kept higher, easier.
Very pleased!
Many thanks to those who helped me BTW!
