Absolutely agree with the first statement about loosing independence. I also see that people use large sway bars to make up for poor spring selection. The sway bar should only be used to tune the suspension after proper selection of the springs. Generally the sway bar will help reduce roll and this will help reduce camber change caused by body roll; however, this could be controlled by more roll resistance by spring selection. A Mcpherson strut car will gain negative camber as the suspension is depressed. Check your camber through your full range of bump and droop.

Will 'tracking' your car void the BMW warranty? I have been told exactly that.

For those of you in the Boston/White Mountain Chapters... be sure to check out one of the best autocrosses in the area. The Boston Chapter holds a fantastic autocross series up on the runways of Fort Devens (in Ayer,MA). I happen to chair the events with a co-CCA member & friend of mine, and we have some really great drivers there (including a handful of national champs), lots of newbies, and a very healthy smattering of people in between, plus a great instructor program. I want to see more 1ers there than mine!! :smile: It's cheap, fun, and if you've never done one before, you're missing out on learning exactly what your car can do! |

I said probably and will probabllydo some autox also. But i wont be changing much with the car itself. For one thing i dont know what to do really ( what is camber and what is a sway bar?) and also i don plan on tracking so much that a little understeer will bother me

There are a few basic books on suspension dynamics that would be a great place to start, but none of the titles come to me at the moment. Anyone want to make suggestions for slipkmaggot?

White911:
When you adjust camber, are you talking about front camber only or are you talking about front & rear? Also to White and everyone else: I'm kind of confused on how camber should be set on a RWD BMW. From what I understand, after lowering the vehicle with properly matched shocks and springs, the car gains some negative camber both front and rear. From there, is it wise to adjust more negative camber up front as apposed to the rear? Keep in mind this BMW would be set for mostly street but occasional track use. Also, if ride height adjustabilty isn't an issue, is going for coil overs a waste of money? I don't want to slam my 135i, because, from what I understand, that retards the roll center of the vehicle, which is the last thing I would want. I also don't want mis matched shocks and springs. |

As a rule of thumb on E36 and E46 cars, front negative camber should be a minimum of 1 deg more than rear negative camber. This is for track. With my E36 setup and Ground Control suspension (including adjustable camber plates in front) I ran -3.5 front and -2.5 rear for track, -2.25 front and -2.5 rear on street.

With Thunderbolt raceway opening here in NJ, track use is the main reason I bought the 135 (for my wife;-)) . Interesting to read the suspension comments. Tracked/raced/tunes plenty of Audis and 911s but first time w/a bmw. Figure I'll get adjustable ARBs and figure it out trial and error.

Nope. No plans to track. I have a problem doing that to a car that really wasnt meant to be. Thats not to say it wouldnt do well. When they come out with an performance version, sure. I'll track the hell out of that.

By high performance I mean an LSD, Lighter weight and a little power bump. And ofcourse nicely done aesthetic touches. :wink:

I won’t be getting a 135 until next year, but when I do it may see a little autocross and probably no tracking. I have a dedicated car for that and I don’t need to build another monster.

That is one of the big pre-delivery questions since no one in the US has a car yet to do a little trail-and-error with. Many of us are wanting to go 18x8.5 w/245x35 all around. I'm guessing it is possible in the front with the right wheel offset or spacers. But until we have the cars it is just a guess.

Probably not much, if any difference. The 135 has the larger Brembo 6-pot brakes though.
