Hi John –
Here is a link to information about the chapter’s CCC program:http://ggcbmwcca.org/driving-events/car-control-clinics/
The Autocross program offers a beginner autocross school in February which is targeted at folks who have minimal to no experience with autocross. We’ve done three of these so far and we continue to evolve based on member feedback.
Hi Paul –
The team did our research prior to this change and we discussed it at length at our annual meeting and all of us agreed that this modification is significant enough that it should be charged points.Facts
– The E9x M3 is equpped with front centering pins from the factory that prevent any camber adjustment while in place.
– It is widely known that these pins are removed to increase negative camber beyond the factory setting.
– If the pins are no longer there, they have been removed.Our classification system assumes any change you make is done so to yield the maximum benefit.
Some examples:
– install wider wheels, assume you run wider tires
– install adjustable shocks and/or springs, assume you corner weight and dial in your suspesion
– change the ECU tune, assume the change yielded a benefit
– install camber plates, assume you changed camber
– remove centering pin, assume you changed camberHow much of a change you make (or don’t make) by removing the centering pin is not for our judgement. I have camber plates and could align my car to the factory setting, but I can also align it to maximize negative camber which I know is a worth-while change for autocross. I’m charged 5 points for having them because the system assumes I will use them to my benefit.
There have been two threads on the FB group, unfortunately deleted, discussing this very topic. From there I learned a few things about the E9x.
E9x factory alignment specs here:
http://www.m3post.com/forums/showthread.php?t=192175That’s -1.10 degrees with a max diff between the two sides of +/- .2 degrees. In the deleted thread I mentioned we saw an E92 post-pin removal alignment sheet with -1.65 degrees. When compared to factory setting this is about -.5 degrees of increased negative front camber. That’s a significant change.
I was unable to locate the alignment section for the E90 M3 specifially, but I do have it for the E92 – Reference
The first page, right at the top aside the large triangle with exclamation point reads:
The centering pin may only be driven or twisted out if the camber
is outside the specified tolerance after toe adjustment.With the pin in place, no front camber adjustment is possible on any BMW equipped with the pin from the factory. We can only assume if someone removed it, that they did so to change the camber as set from the factory.
Our policy is consistent with the 2017 Street Category Rules where Section 13.8 B reads:
Both the front and rear suspension may be adjusted through their designed range of adjustment by use of factory adjustment arrangements or by taking advantage of inherent manufacturing tolerances. This encompasses both alignment and ride height parameters if such adjustments are provided by the standard components and specified by the factory as normal methods of adjustment. However, no suspension part may be modified for the purpose of adjustment unless such modification is specifically authorized by the factory shop manual.
SCCA also recognizes the potential benefit of alignment changes and addresses them specifically in their rules.
Hope that helps! Please don’t delete as we lost a whole bunch of good dialog from the FB group and others will benefit from seeing this.
Hi Justin –
Dates are not finalized because we’re waiting on the FAA to approve the use permit, as usual. Last I heard it was looking good, but they were to respond by 12/31/16. I have yet to get confirmation on that.I’ll create a sticky with the dates we have requested so everyone has an idea of what the schedule will be when approved.

To the top! I’m really looking forward to driving this one again, and especially for the creator to get a chance. Dave missed this event and couldn’t enjoy his own course back in June.
I’ll have some printouts with the grid present for the setup crew tomorrow morning. There was an issue with the software that produced the image above, but we’ve figured it out.
Here’s the update:
Dave did design this one too. The dude has been busy for the last four weeks and has TDS to do still. He needs a raise! 🙂
Well, Mark, it was really fun! Brian let me drive his monster E30 and I had an absolute blast! It was fast, flowed great, really nice course.
Top two from this season IMHO!
Now that we’ve driven it, what did you think? 🙂
Personally, this was one of my favorites! My biggest challenge was the corner after the slalom. I think I did it “almost right” one time, the rest of my runs, not so much.
… But the real star of the show, in my opinion, was Brian’s 911 :D.
I had a poster of that exact car on my wall through college and several years after. It was my inspiration to stay on top of my game. I never got to own one, but did get treated to a ride-along. It was just as fantastic as I thought it would be. Brought me back, way back. 🙂
