Control arm bushings

[bowtie2bimmer]

I know its common when replacing the control arm bushings to get the m3 offset versions. From what I've seen its suppose to help negative camber from a lowered car. Currently my car is stock height (cabriolet btw) but will be doing the H&R Touring cup kit within the next 12 months. Is there any other advantages to getting the offsets? I have a bad control arm so while replacing it I was going to do the bushings...

Offset control arm bushings don't affect camber, but they do increase caster. Which increases high speed stability.

If you are changing the CA's of course you need new bushings. I just swapped my Cabrio to the offsets (when I did the CA's tierods & e36 swap) and the offsets change castor not camber, which essentially makes the car want to go straight. This gives you better high speed stability but IMHO also adds a bit to steering effort (since the car is saying "Im enjoying going straight")..not enough to be concerned about so def a good mod.
