try nissansilvia.com for the brakes n coilovers...
i got a brand new front pair only from ISC coilovers with camber tops for 700 posted!
also with the brakes theres plenty of s13 sr20det setups as most silvia guys upgrade to 5 stud... i got hubs, calipers, machined discs, n spindles for 350 delivered from 'garage13'
ps the spindles are what the coliover, calipers n tie rods bolt to n attaces it all to the lca.... ps im using sigma lca's n looks to be fine, just not yet completed.
cheers
