My R53 gets a lot of track and autocross use. It is not a DD. I have KW V2 coilovers, Vorshlag Camber Plates, an H Sport Competition Rear Sway Bar, and an M7 strut tower brace.

My tires are wearing more on the outside (sorry, don't recall the current camber settings), so my mechanic suggests more camber, but this would require rear control arms as the current setup is at the camber limit.

What do you think about this and if control arms are the way to go, which brand of control arms?

It always comes down to how much do you want to spend...

...there are a large selection out there, just what you want... like

what ever you decide, it is up to your Tech to make the adjustment to bring the geometry back to provide you the contact patch you desire and with luck that will reduce the tire wear.

Motor on!

 

Is it front, rear, or both tires that are wearing on outside?
What year is your R53?
2005 and 2006 have adjustable rear control arms (but only slightly adjustable).
Your post talks about rear control arms so I would guess rear but that surprises me because the R53s usually have too much rear camber, especially if lowered, which wears out the inside not outside.
I would tend to suspect your toe is off causing the tires to scrub across the road.
I would suggest something around -2 to -2.5 camber in the front and -1 to -1.5 camber in the rear. I run 0.0 rear toe and just slight toe in the front.

For adjustable rear control arms I would suggust H-Sport or TSW. The NM look like an option but I do not know anything about them. You could call WMW and ask for a suggestion based on you use.

bought a set of these just to test out and very happy with them so far. The least expensive set out there and use rubber bushings instead of Heim joints so they are as quiet as stock. Very heavy duty so would not suggest if looking to drop weight.

 

seems unusual for it to be wearing like that? toe settings?

it may be as simple as upgrading the bushings, you may be getting some flex in the rear during cornering.

 

Outside edge tire wear on rear tires is not common. MINIs are known for having too much rear neg camber so wanting more is odd.

Outside edge wear on front tires is perfectly normal, and needing more camber up front is what you want.

So make sure we are talking about the rear. If so you may have a toe issue, or worse the rear trailing arm bushings are worn out causing the wear. If so let us know we just got some new poly rear trailing arm bushings to solve that issue.
