If he is on a budget of $1k, spending $400 on ANY bushing kit isnt worth it for now. Sure, when he has more money then buying a bushing kit is all well and good, but his first post gives a $1k budget.
Edit: fyi mine is a bitsa. No one supplier had an entire kit available, LCA are "Nolethane" brand, trailing is Superpro and one stock. Castors and sways are Whiteline.
