The MSRP for this is $2,490.00. The full chassis kit including sways (ANTI SWAY-BAR KIT HOLLOW 30.2/25.5mm ADJUSTABLE E9x M3) is $3210.00.

Sways by themselves have an MSRP of $720.00

Based on their website,

The RDSport Chassis Kit includes uprated struts and springs providing an 18% increase in stiffness while lowering the vehicle 1" in the front and 0.75" in the rear.

graider · 05-01-2010, 09:01 PM

why do most coilover allow more drop on the front than the rear. wouldn't it better for handling to drop like 1" all around than say 1.5 front/1rear?

rzm3 · 05-02-2010, 01:30 AM

Most kits have adjustable heights, so you can fine tune it to your own liking...
