I really like the rear sway bar from dorman on rock auto or summit(cant remember). We do have a short style tract so speed is a problem for mi.
Gotta do something about the diff as open will make you spin out and harder to initiate the drift. Also need a hydro as its hard to bang gear and pull the funny ebrake.
Make sure your cooling system is in good order Im on mi fourth head gasket and second head.
Up front Im running 195/55r15 on these wheels https://www.summitracing.com/parts/USW-78-5860R, also there is some rub at the back of the inter fender but a little work and they fit for mi.
Back I have four 620 14in and 8 d21 15in for burners all steel, aluminium would be best for back to help spin the tires. Tires for the back, get the cheapest walmart junker.
4x4 springs in the rear with kyb gas-a-just, saving for blistens.
Biggest thing is keep your power steering, got mi truck with out it as the person before mi removed. spend all last season not being able to turn the wheels fast enough to complete the transfers.
Bucket seat.
