Need recommendations on Negative Camber

Hi guys, I have lowered my car on kw v1s and would like to reduce my negative camber. My car is my DD and I'd like to get some recommendations for the amount of camber I should have. I'd also like to know what the stock setting BMW sets the camber at.

I have a staggered setup with 235/35/29 and 275/30/29.

Thanks guys.

For rear wheel drive models with sport suspension, the stock rear camber is typically around 1.6 to 1.8 degrees.

When I asked for the rear camber to be set minimum, it came out around 1.1 ~ 1.2 degrees. The tire wear has been quite even with that setting. IMO, around 1.3 to 1.5 degrees should be pretty fine as a general recommendation.

Thanks for the info. Forgot to mention that I've got an xi.

If you're concerned with tire wear, pay more attention to your toe settings, rather than just the camber. You'll find many threads in the wheel and tire section about premature wear, and most people blame camber, but the true culprit is their toe.

Thanks. I recently got new tie rods, inner and outer, went to get an alignment and was told that they couldn't get the front camber even. One side is at -.7 and the other is at -1.4. Is this because I'm lowered? Do I need to purchase camber plates?

Also, can someone give me some recommended numbers for toe and camber for a lowered xi. I'm looking for relatively even tire wear, but don't want to sacrifice too much performance. Thanks.

toe should be zero or close to it, unless you need to adjust for fitment clearance. Are you lowered all the way down on v1? Camber in rear shuouldnt be much of an issue, and if you need negative I cant imagine anything more than 2 degrees or so

This.

Case in point - I'm running -2.7 degrees in front and -1.5 degrees in rear with zero/slightly negative toe. No abnormal wear at all.

I'm lowered roughly a bit higher than half way in the front and at the highest in the rear.

For the front camber it looks like you may have some damage or tweaking of the frame. camber should not increase much (if at all) on these cars when you lower them (unlike a double wishbone design in Japanese cars). You should do some searching about the front alignment pin. There is a pin in the front strut hats that locks it to the chassis. The bolt holes for the hats are slotted. You can pull this pin and adjust camber that way.

Like VMR said though, toe has much more to do with tire wear. I actually set my front camber to the max negative I could get with the pins pulled (about 1 degree) and had the shop set the front to zero toe. I have seen no adverse tire wear from them and it improves the handling and turn-in of the car greatly.

The rear camber is fully adjustable and again, will not change significantly with being lowered.

Thanks, did some research and depending on if I can get it to were I want it to be I may get some camber plates.

Is your car a DD? What's the max you got your front camber to? I'm thinking -1.4 would be good for me with 0.0 to -.04 toe on each side. For the rear, -1.8 camber on each side and 0.08 toe. However, I am seeing a lot of ppl with more camber in front than in the rear. What's the difference?

I honestly don't know what I really want but based on the research I did, the numbers themselves seem relatively conservative. BTW, the car is a DD and a mainly a highway warrior but I live out in the woods with lots of twisties. So I run through the twisties every morning and night. So as much as I want straight line stability, I don't want to sacrifice my fun going to/from home. Basically just looking for that decent compromise.

My car is a DD. I put around 1000 miles per month on it. Here is a link to my post with my alignment: http://www.e90post.com/forums/showpo...90&postcount=4
