Dont hate the player hate the game,cos if you could do what I do,as good as I do it,and look as good as I do doin it,youd be doin it too mate ;) FACT !! ;)
4 wheel geometry is where they get all 4 wheels pointing in the direction they should be,ie nice and straight,not sticking out/in or too much +/_ camber as to not cause any excessive wear on parts connected and most importantly tyres !! I used to go through a set of rear tyres every 6 months max until i got it done. Some of the best money Ive ever spent :) Ive had my current tyres on over a year now with no wearing issues at all :) and I dont hang about and also have the tendancy to do a little sideways action ;)
Bought a e36 320ci with an overheating problem for 250 quid and sold it for 350 quid :) minus the Kenwood head unit,6x9s and a few other bits an bobs that I raped off it :)
