Please forgive my ignorance but I'm trying to understand what is allowed when setting my car up for autocross. According to what I have written below, copied direct from the 2012 SCCA Solo Rules pdf, can I run non R3 18 inch 2010 rx8 wheels on my R3?
13. STOCK CATEGORY
Option package conversions may be performed between specific vehicles
of a particular make and model, but only between configurations
from within a particular model year.
13.4 WHEELS
Any type wheel may be used provided it complies with the following: it
is the same width and diameter as standard, and as installed (including
wheel spacers if applicable) it does not have an offset more than
+/- 0.25 inch from a standard wheel for the car. The resultant change in
track dimensions is allowed.
Wheel spacers are permitted, provided

Ok so I looked into the classes for the club that I plan to run with this year. They do have the "ST" class. But they classify it as "STA" ( street touring all) They group STX, STR, STU and all those into one scoring bracket. That's why I assumed they didn't have a "STX" classification. because I didn't see it listed
Is that normal?. Im sorry to be such a noob but I'm really excited about racing this year since I got a taste of it last fall. And I just don't know much about it. Trying to build up a knowledge base now for the spring so I don't make a fool out of myself. I hate the idea of being that guy with a nice car but don't know **** about whats going on...
I'm not apposed to running in stx but I'm not sure how much of a contender I'd be. My car is mostly stock. Its just that I work in a tire shop go I get tires at wholesale price. Therefore I don't mind wearing them down too often but even at wholesale price the 19 inchers are pretty expensive.
the regions are free to change a number of things different from the National rules to suit their local situation such as the STA classing
they could even allow you to swap to the 18" diameter if they saw fit to do so, however you have to run the National rules at National events
The SEB just did something similar for the Camaro for the Stock, they are allowing it to use 19" wheels rather than the OE 20" wheels since there are no 20" race tires.

You might want to double check that one... My understanding is that did not pass. Something, something, big can of worms.
I thought it went out as a fact, not a proposal but I was surprised that it was even considered given the historical can of worms philosophy that has proceeded it. It seemed like just another one of the new trend ideas that are bucking historical trends so I didn't really give it much thought at the time. Kind of like the street tire Stock class nonsense that is now part of the National Series, which makes the rule change we are discussing above moot since they can run their two ton goliathes there instead.

We did put out a proposal for member comment allowing substitution of 20" wheels with 19"...it didn't get traction
We'll see how the tire manufacturers respond to the growing number of performance cars rolling on 20's, but up to this point, the usual suspects have not indicated any interest in producing tires for the application. If they do, we could see the breaking of the $2000/set barrier.

back somewhat on topic - are there any off-the-shelf 19s that would work for the R3 and be CS legal or CS legal with minimal spacer use?
People want way way way too much for OEM R3 wheels, but still less than custom stuff afaik.

The r3 wheels are 19x8 + 47. The rules state you can use up to .25 offset deference. .25 inches equals 6.35 mm. so in theory you can get a 19x8 + 42 and be legal.
I just did a real quick search for you but its hard to find them. most are 8.5
So the only good choice is the RPF1.
