I paid:
$400 for new GC coilovers
$500 for new illuminas
$200 for new MSA front/rear sways
$450 for new toyota s12w calipers, spacers, z31 rotors, pads from mike gibson (scca)
$60 for 4 earl's braided ss brake lines
$350 for used r200 lsd 3.7
$140 for new full ES bushings kit
$200 for rear disk brackets from Ross (240sx calipers were free, but let's assume $100 for them)
$100 for a pair of rear z31 rotors
$30 for rear pads
So far I'm at $2,530 with more than half new parts. Labor, obviously, done myself. Unless it's a quaiffe LSD, it's nowhere near worth it. plus, parts are used, and auto accident = stress and shock? We can assume $400 for rear A-arms, front LCAs, TC rods, etc... which is still less than what he's asking.
My opinion, however
