No way I'd autocross on OEM steel wheels!
What I was getting at in my other post was, if the intent is to have some type of logical progression from Stock/Personalized/Modified, leaving tire compound wide open doesn't make sense to me. And I also was suggesting that suspension modifications could be clarified to make it easier to know exactly at what point you've made the jump to another class. I've been on rules making committees for SCCA autocross and have spent time on these types of discussions in the past...not that that makes me any kind of expert on what works best for the Tiger clubs!
If the goal is to have fun and be Stock (given LAT options and using my tire limitations), I'd max out front camber/smidge of toe out, add a set of adjustable shocks, LAT70s with good street tires, LAT6 traction bars, LAT50 diff with 3.31s. That would be enough to have fun...of course, adding the Holley/F4B/cam/tri-y's might be even more fun

Rick,
I thought Stock meant stock, not just kinda, sorta, stock. So why have a Stock category in the autocross if we aren't going to require cars to be STOCK? There is nothing wrong with people who want to wring the most out of their cars by making changes, but please don't call them stock. And some folks strive to keep their cars as stock as possible - don't penalize them for doing so while autocrossing in the Stock class and competing against cars that are MODIFIED. Note that I advocated for stock size wheels in stock, not necessarily stock wheels which are know to have weakness issues.
Back in the early 70s, autocrosses in SoCal were usually held under the rules of California Council of Sports Car Cubs (SCCSCC). They only had two classes - stock and modified. But then SCCSCC did not oversee concours contests.

Mike, you made great points.
The "reason" tire compound has not been recently mentioned is simple: many were "cheating" and slipping them in and the organizers did not want to throw people out. As one Chair said, "This should be a fun vacation. I don't want to be the bad guy." "We'll just p____ some body off and they'll never come back. Like R_____."
When we realized the reluctance to enforcing the rules we backed off and got rid of the tire restrictions on the theory that leaving them in place would just benefit the cheaters if we didn't enforce them. Maybe it's time to revisit the issue.
On a different subject, where do you think quick racks should fit?

Limit the stock class auto x cars to have 165x80/13 tyres... If they want to run sticky compounds in that size... Let them, but keep stock size...
Interesting history on tire compounds...and speaks to the issues of trying to regulate what are typically smallish total entries within "marque"
There's so much noise associated with "LAT option" that I just don't know if it is a good thing or bad thing to include in "Stock". You have some options that were commonly installed at the dealer, a few that maybe/might have been installed at the regional level, a few that were just line items to be exploited by Doane and none of them installed at the factory. But, the Tiger community feels that the filed FIA papers are enough to make them legit for our autocross use, so that's what we do and why I included them in my hypothetical "stock build". Ultimately, many sanctioning bodies (cough, SCCA, cough) chose to take the clearest path and disallow all LAT options, because of all that noise, as you know.
Quick racks, far as I know, were built by an individual (Bill Miller) with not even indirect factory involvement. I can't see any rationale to allow in "stock". I might be missing something, though. And, yes, I know some have run them in "stock"...along with hipo motors, shorter/stiffer front springs, de-arced rear springs etc.
That's one way to look at it, but I'm not sure that a 165/80-13 on a 4.5" rim would be either "fun" or well supported? Also, you'd have to source 13X4.5" rims with adequate strength, as well.
Given the current allowance for LAT options opens up 5.5" rim width, you could just mandate a minimum tread wear standard to limit "tire". Section width will be self policing, as there's a point of diminishing returns in trying to pinch more width onto a given rim size...plus clearance issues. The most widely supported standard (Lemons, SCCA, Chumpcar, Optima etc) for street tires is 200TW.

I have a Rootes Motors (Canada) Sunbeam Special Accessories brochure. There are a number of LAT options shown so they were available in Canada. I always found it interesting that the brochure shows the LAT 1 " Super Tiger Induction Kit " with a Stellings and Hellings Air Cleaner as part of the package - just like the only Super Tiger was equipped. I put my original Air cleaner away and put on a Stelling and Hellings when I restored mine because that's what it shows.
