I use tein s springs and KYB SR ultra suspension struts. Makes for a very good handling car and low. But not too low.
Was good enough for 12.13 @ 113 mph
Hmmmm, could be internet propaganda but I looked at the Tein S Tech springs (are they the same?) and there were more bad reviews than good?
I think I would prefer an 'all in one's package, don't fancy buying everything separate. I looked at the Pedders Ezi kit but these also are reported to be too firm.
