haha yes I did ARB before stage 2, now going ALK before stage2+ later this year to give the car more grip and better turn in. Coils would be nice however its another 1-1,5k to fork out that I dont have yet to spend, maybe early next year. You may want to think about brakes too at some point but again its over a grand or two for a decent set so not cheap but very important if you often plan to push your car very hard.
