depends you could improve it alot by a beam and 3 door front hubs , then you could go adjustable track control on the front ect and have the konis re valved and better uprated springs then change the suspension by have the car corner weighted with coilovers which are again suited to the car properly with spring rates and damping , stay away from black art kits there a nasty build quality and from what ive seen there valved incorrectly anyway . If its a cheap kit then have the car weighted on all 4 corners and overall weight then give the info to dave lyons at gaz and he will valve and spring it correctly , but if your going the whole hog then its ohlins without doubt
