I have a mk2 golf 1.6cl 4+E which has lowered suspension aftermarket alloys(£0 value) with locking nuts, aftermarket bigbore back box. I am currently fitting a 2ltr 16v to it, my insurance quote from HIC just now is ~£850 but i intend to fit uprated brakes. what else would HIC like to see on the car to lower the quote?
