informed my insurance co (tesco)today, of minor mods, exhaust system, lowered springs, induction kit. yearly premium is 580.00 and now with mods they want an extra 97.00 until may which equates to well over 200.00 extra per year. makes me think is it worth it as probably only about 10-15 extra bhp. ( car is 02 wrx.) had a quote on a sti ppp @ 750.00 from tesco .they are clueless.
