you really need to get rid of arb and put some proper coilover on it and not the gaz's some billies would be nice like the ones mef did and all your other ideas for the front i currently run with a propper motorsport rack and you just point it where you want to go and it drags itself there and rides lovely on bumpy roads no being pulled from side to side, the rear to go adjustable really you need coilovers and rear discs to push wheels out and then bin rear arms for adjustables but you will need to go to a specialist to get all that set up but will handle a treat and with 200bhp make a great lively car
