I joined a long time ago, only got around to buying a 5 yesterday. Ive no intention of leavin it alone

Lowering springs or maybe coliovers if the price is right
Cage or a roll bar
Torsen Diff from a 1.8 c/w prop & half shafts preferably with a 4.33 Final drive from the newer models but if I cant get one Ill figure something out over the winter to give her more go.
