Default unsprung weight

anyone autocross?

anyone have any ideas or part swap suggestions to have lighter suspension parts?

going coilover front end and eventually IRS in the rear.

lighter hubs/knuckles/ spindles?
lighter calipers?

this 6 bolt wheel assembly is a big chunk of weight.

Foul Mouth dabbles with a little racing. He would be the one to ask.

Well, unfortunately you dont have many options out there..


The only thing i can think of is lighter rotors, wheels, possibly calipers.

aftermarket support for racing a 20+ year old truck is pretty slim.

i understand the no aftermarket part. but there are other oem parts from other cars that fit.

sourcing lighter wheels and tires now.
v6 calipers or use 300zx ones? possibly lighter.
the Subaru steering rack might be lighter. il do that when I do LS swap.

cutting out some cab floor for aluminum diamond plate and rivet.

So my next question is, how are you going to keep traction?


HP and TQ is useless if you cant get the tires to hook up

Are you going straight into modified class?
I run American Racing outlaw 1 wheels 15x8. They are pretty light with my toyo proxes ra1 225 50 15" shaved r compound tires.
If you engine swap and you run scca you will be dropped into modified class which is very fast. Just be aware of that.
