is there anyone who has replaced the factory bushings with the BMW Motorsport ones?
As here: http://www.turnermotorsport.com/BMW-...nd-mounts.aspx
I'd like to know your thoughts... any downsides to doing this?
Also, is there any risk to doing this for road use? Are you raising your chances of bending stuff on the street?
What about the Turner Delring subframe bushings - anybody running those on the street?
Also, how long/how much longer are these Motorsport bushings going to last when compared to OEM 335i or M3 bushings? I've heard Powerflex polyurethane is a once-a-lifetime affair (or so they advertise it), so I'm wondering how often you have to change these motorsport parts?
Front Lower Control Arm Bushings (LCAB) - Motorsport Race - E82, E9X (Pair) - $99
-- This seems like a no brainer at the price
Front Upper Control Arm Bushing (FCAB) - Motorsport Race Rubber - E82, E9X (Pair) - $413
-- Stock rubber costs $70, not sure how much labor is? Any way, are the race rubber going to last say 5x as long as the stockers?
Rear Differential Mounts - Solid Delrin Race - E82, E9X - $249
-- sounds like a good deal given you don't ever have to replace them?
Rear Guide Rod Bushing - Inner - BMW Motorsport Race Rubber - E82, E9X - $108
-- price is reasonable, not sure on the stocker price?
Rear Guide Rod, Upper Link Bushing - Outer - BMW Motorsport Race Rubber - E82, E9X - set of 4 for $460
-- also reasonable price?
Rear Lower Link Arm Bushing - Inner - BMW Motorsport Race Rubber - E82, E9X - $100
Rear Subframe Bushings/Mounts - Front Pair - Motorsport Race Rubber - E82, E9X -$400
Rear Subframe Bushings/Mounts - Rear Pair - Motorsport Race Rubber - E82, E9X -$400
-- sounds a bit pricey given the fact that the M3 bushings are $255, sooo.... are these going to last 4x as long or?
Rear Toe Arm Bushing - Inner + Outer - BMW Motorsport Race Rubber - E82, E9X - $250
Rear Trailing Arm Bushing - Inner + Outer - BMW Motorsport Race Rubber - E82, E9X -$250
