Yikes.
You remove the rear sway bar because you want to use the front for roll stiffness and the rear for forward bite. Trailing/Semi trailing cars really hate rear sway bars though. I tossed mine in the trash too.
Powered by max is the local legend coil over of choice since its way oversprung under dampened. makes the car slide easy and feel go cart controllable. won't be great for actual grip.
Toss some sub 1600$ coils at it, Fortune, Stance, BC, pick your favorite color who cares. no stiffer than 8/6kg, digressive valving with helpersprings is great since every track that is cheap enough for drift events to rent is worse than the surface of the moon.
Assume your V8, spools work fine since you don't need the off throttle grip as bad as a big turbo 4cylinder if you're peasant just weld it.
Cut steering knuckles, don't jump into cut knuckles imo, they'll teach you bad habits if you don't know when/why to use the extra angle.
Solid bushings, every car works better when stuff doesn't move around all weird.
That stuff and a seat, George Marstonivic makes some good rack spacers so you won't have to jump into cut knuckles.
