I have to say, that looks like a very cool car! I'd love to see it at our next event. Are you trying to dial it in, test it, or just have a fun time?

When lawyers get involved, all bets for a rational outcome are... influenced . And insurers rely on their lawyers. I'd be willing to bet this isn't the SCCA having a concern, but the SCCA dealing with insurance repercussions. If you have a Jr in the program, I suggest you sign up with Brian and part...

And FJ is a group of supplemental classes, so the SEB can easily and immediately change rules if needed. Edit: To be clear, I am not an anti-FJ person. I fully support the program. It's just that FJ is the only category where not only does everything in grid have to be motionless (besides FJ, that i...

I have no dog in this fight, but in my opinion: no. CST already covers everything that's in XS. If there's an index for XS, I'd suggest keeping whichever is "harder" - XS or our basis for CST. We don't need people gaming the system on soft indexes to mess up the year-long competition for d...

Having seen all the uproar and the retraction, in retrospect I have a few thoughts: The impact on senior volunteers, like Ops Stewards, is likely the biggest negative from an operational standpoint. I think few people care about that, but given the SEB's responsibilities in managing Nationals, I kno...

Basically, it's our CST. We've had this for years, if not decades.

It's actually a bit more restrictive than what we have though.

Yup. For comparison, I happen to like ARC wheels for my BMW. They're what I use on the SM M3, and I was thinking of getting an additional set for use on the Berry STX car. They have a new forged wheel, which I figured would look nice, be strong and fairly light. https://www.apexraceparts.com/wheels/...

I suggest weighing one. Check some other sizes’ weights on their site. Smaller wheels seem to be heavier, and they don't quote weights for marginally larger sizes. Seems odd to me. They might be accurate, but it seems worth a little more due diligence before you buy a set of wheels and are disappoin...

I’ve been checking out 17” STX wheels Steve. That seems to be right in the ballpark.

We weighed one of the current wheels on the BMW when Marshall was installing some new tires, and they were 17.5 lbs on the scale he had available.

Hi Emon. The easy options for you are a local class we call CST (California Street Touring) and CAM C (Classic American Muscle Contemporary.) CST is basically any street-licenseable car on 200 or greater treadwear tires. It is frequently our most popular class. CAM C is a national class, and you can...

What's the use case Bill? If it's just jacking up to put jack stands underneath or to change a wheel, what about a short ramp (aka "2x6") for a little more jack clearance and stick with the racing jack?

I'm not familiar with the distinctions between NC1, NC2 and NC3 engines, but there are two other key points to research before declaring this a Hard No: Is there either a Tech Bulletin from Mazda stating that replacement NC1 motors must incorporate the NC2 or NC3 components or configuration? If that...

I propose local modifiers for discussion:

• Teslas to SS
• HS to .783

Hi Reed!

Here's an interesting utility sheet:

The "Chris Teague" rule! He always says if you aren't sure what to do, drive the short line.

This is very cool of Anthony to host. Anybody who is participating in our events should join the seminar. Anthony knows his stuff, and figuring out the right line is one of the fundamentals required to achieve your best results. Thanks Anthony for doing this. PS Adding this: did anyone else *not* kn...

Nice!

How often do you drive courses that don't require shifting after the start? I haven't watched any CM videos before, but I guess I imagined a lot of shifting involved...

I noticed that at our most recent event - on a Cayman.

Which model(s) were you hearing that sound? I'm wondering if it's a unique sound they developed for the "new" turbo cars. It's not quite as unique and pleasing as the air-cooled 911 engines, but it's definitely different.

We're also hosting another event on Oct 5/6 at Santa Anita. If you join us for that, I believe I'll be the safety steward. Feel free to join me for a course walk or two before we start running.

Hi Patrick - welcome to the forums and to autocross! It's entirely up to you, but I'll put out some suggestions: Do you have a lot of spare time on the weekend and you're less concerned about budget? Do them both. Lots of spare time, but want to be a little careful with your budget? Sign up for Sund...

That course is my favorite of 2019 so far. I had *so* much fun!

Thank you Christine for penning it, Michael Bradley for leading the setup on it, and Marshall and Tom Frecentese for the Saturday evening modifications.

Man, that venue looks great for us. The palm trees, the mountains in the background. Does it get any better?

Thanks Ed. Really nice of you to take those.

Mike

David, Even in Street Prepared, you're not allowed to move the spring location. If the car wasn't a coilover configuration from the factory, you have to go up to Street Modified before that's a legal conversion. I am not familiar with the pre-E30 configuration. Are the rear springs around the damper...

I'll add that the storage facility is at the intersection of the 210 and 15 freeways. It's called Victoria RV and Boat Storage.

Just in case anyone wants to look up the location...

Regarding sound, the official test procedure (for car manufacturers, which is also referenced in California law) specifies the meter be located at a 45 degree angle from the exhaust tip, at the same height, 0.5 meters / 20 inches away. The throttle is applied slowly over a period of several seconds ...
