Ok, I've taken the dive and dump $150 USD for a set of Eibach Sportsline, shipped. So it is about $275SGD for that springs... I think I got it cheap, as the market price is $175+shipping.
HOWEVER, Tein springs only sells for $100USD. I wonder why the big price differences. I realized that the bigger the drop, the cheaper the springs are. I guess it is due to supply and demand.
Front drop 2", rear drop 1.8" I'll install it in a few months time, after I've moved.
