if u wanna be cheap just buy some BILSTIEN front legs including disks calipers and bearings...
buy some 190lb springs and a anti-dive kit (rallydesign) tots up about 200quid (saying the bilstien with calipers disks etc are 120quid) and ur paying full postage. the handling will be brilliant, the brakes wont fade...... for about twice the distance as the standard ones...
(i say put the anti dive kit and 190lb springs in while you do the shock absorbers and brakes because they are a c**t to do the first time but once they are done you'll love it!

p.s. bilstien (blue shock absorbers) +calipers and disks come regulary on ebay if you want mk2/3 items.
