just stay 4 lug rock se's cut ur springs get a welded and learn how to slide and when u get better start buying 5 lug suspension arms coils and what ever else u want to buy
im in a bone stock ka with suspension and welded diff. its difficult but ull get use to it and when you go sr it will easier. and j30's go retarded after a while so when ur j30 gives out at 10000 miles welded it.
