Will it cost more or less than a coilover kit do you know roughly? (coilover kits about 300?) obviously i would like to spend as little as possible with the suspension, but still have fairly good quality (not dangerous) so i can put more money towards rims, id like to go no smaller than 18's really.
If you saw a brand new set of coilovers for £300, then I'm sorry to say but they would be crap!! If they are the sets off of ebay, or even the Jamex kits they are only height adjustable, with sh1t springs that give you same ride quality as the pedal go-kart you had as a kid, i.e, NONE!
Take a look on
www.motorsportworld.co.uk this should give you an idea of how much it would cost for the Koni/Eibach kit, or even if you can save a few more pennies go for a set of coilovers which are from a reputable firm.
Also have a gander on
www.uk-mkivs.net in the classifieds and the suspension forum, someone might be selling a bargain.
Also to note, if you go too far on the drop, you'll need to replace the front anti-roll bar links as the bar hits the driveshaft anything over 60mm, alternatively FK do a replacement roll bar for about £100.
