Koni sports adjustable cost sgd$489 front and back for E30 4cyl. Get it at Selegie Spare Parts, Singapore. I just got one set and they left 1 set only, they just brought in 2 sets for e30 4cyl this month. For 6cyl i think they still have a few sets available. Spring's i don't think you can get them right now, i manage to get Merwede lowering springs for SGD$180 from Fong Kim Exhaust and thats the last set left. Was running around whole singapore trying to get Eibachs Pro kit (quoted $480 from 1 source but must order cause no stock). Selegie spare parts brought in vogtland but available for 6cyl, 4 cyl not available so must order. Vogtland springs SGD$160-180 quoted from selegie spare parts. Last enquired for bilstein sports B8 from Eng Soon, left 1 pair front for e30 318IS, think it fits 6cyl strut only. Heard they are not bringing in any more sports suspension etc for E30s.
