1st time Auto - X with the 135i(pictures inside)
http://tinypic.com/view.php?pic=16says&s=6
http://tinypic.com/view.php?pic=ioiwt2&s=6 Just bought my 135i(2009) ~ 1 month ago. Current mods are: AST 4100 coilovers (550 /784 hypercoil springs), cobb stage 1 linear, vorshlag camber plates(set at ~ 1.85), hankook v12's(came with the car used) Got a chance to take it out to auto - x with speed ventures. Had a blast learned alot about how to drive the 135i throughout the day. I believe I did pretty decent compared to the rest of the "competition" there. Placed myself about where I would expect(slower then the evo 9's, miata's etc, but fast then the mustangs, 335i's, prelude's etc.) Impressions: I definitely felt the understeer, especially on the sharp S's. Overall felt good. This was however a LOW speed course were it was very difficult to "put the power down" at any spot on the course(yes yes I know its an autocross course). I think the fastest you could get on the course ~ 45 mph maybe 50. As for the AST 4100, I think they were great....eliminated most body roll and the ride quality is great (even on the crazy pot holes over the 10 freeway). In fact I think the ride quality and comfort is on par with stock M suspension if placed on the softer dampening settings. For the auto x I was running stiffest in the rear and 3 clicks from stiffest in the front. Anyways had a blast, I think my camber in the front and better tires next time running will help my times alot(Rs3's!, ~-3 degrees camber) Last edited by tlee55; 05-09-2012 at 11:21 AM.. |

LA chapter (next auto-x May 20th): http://www.bmwclubla.org/calendar.php San Diego chapter (next auto-x May 12th): http://sdbmwcca.com/ With the BMW club, you get top notch FREE instructors and will learn so much more than you can learn all by yourself. The're a great bunch of people coming to the BMW events and I'll bet you'll leave not only with a whole lot of new driving skills, you'll also make a ton of friends there! Also, the BMW club is usually a bit more safety minded than Speed Ventures seems to be (still can't believe they put a slalom that close to that curb): Quote:

That said, the large parking lot at Qualcomm does allow for higher speeds: Quote:

Come down to San Diego or do the next event at the Speedway with the LA chapter! You'll have even more fun than you're already having! |

Thanks for the tips. I will definitely play around with my dampening settings to get a better feel for what is better(I started at 4/4 in the beginning of the day).
I was there that day when the corvette crashed. The crash was definitely a mix of a series of unfortunate issues(driver skill or lack there of and bad course design, which btw was set up by the Porsche club of america's orange county safety instructor =), his name is Chuck). I will definitely check out the BMW autocross events, especially considering speedventures is not hosting an autocross until august. Anyways thanks again for the tips. |

Wow that space is huge compared to what we have in Colorado. I have been considering a similar coilover set up but was going to go with a ~350lb front spring. I am glad to hear it is still comfortable with that much spring.
