Anyone here heard about STD Suspension? I recently sent them an email for a quote since a coworker of mine (not a bimmer) suggested to check them out. This is the reply I got and it's cheaper.
"Yes we have suspension systems for BMW E90/92. For the 335 XI model, only the spring rates should change, I called our local BMW dealership and he confirmed that the suspension should work on the XI.
We recommand you the Std R3, everything is adjustable, height, pre-load, compression and rebound. The kits also includes the front camber plate.
With a KW V3, to lower the car you need to lower the springs, therefore you lose shock travel, with our systems, you adjust the height by the lower mount, therefore you keep 100% of the suspension stroke travel"
