Full set 30 way adjustable for S15 but would also suit S14. 8 kg/front and 6 kg rear springs. These did about 15,000 Ks on my car and were only replaced because I had a set of Bilstein coilovers built to replace these. These were priced at around $ 1500 new plus the adjustable strut tops at the front were about another $250. Supposedly the same as BC RA series coilovers being sold by Just Jap for $1399 now, http://justjap.com/bc-racing-coilover-suspension-kit-nissan-s15-d-27-ra.html.
PRICE - YOURS FOR ONLY $1000.
