Are 5 lug and suspension arm swaps legal?

[Chip42]

Greg, wasn't that "clarification" since retracted about swaps between the 99-00 NB and 01-05 NB Miatas which the rest of the world considers to be the same cars with different engines and some minor updates to trim and lights?

I agree with tGA, though, a part is either stock (or stock equivalent) or not stock, and only stock is allowed unless permitted to be changed (I.e. brakes).

BUT given the lack of replacement hub availability on so many cars it might be nice to have some sort of allowance for better than stock or at least similar to stock matches, as long as you keep the stock knuckle and bearing OD, who really cares?

Yep, I think you're right. Which is why it was that much more confusing...

...might be nice to have some sort of allowance for better than stock or at least similar to stock matches, as long as you keep the stock knuckle and bearing OD, who really cares?

I suggest that idea is within the general philosophy of the class, as long as modifications to the car are not required to make it fit. If you (or anyone else) can come up with some non-intortuable verbiage, submit it for consideration. Make it snappy if you're looking for implementation for 2014...

I drive a Toyota, an old Toyota. STL is not in my immediate future. I do have some other ideas for STL options though

Ok this leads me to my next question.

2. Rotors -
Any 1- or 2-piece ferrous rotors that do not exceed 290mm
in diameter and 28mm in thickness are permitted.

3. Calipers - Any 4-piston or fewer calipers may be used.

So if we can run any 4 piston caliper and ferrous rotors up to 290x28 which is most certainly bigger than what most of the car in this class come stock with. And you can't go with OEM (not same model) knuckles/hubs to get the bigger brakes to fit OE.

Are we then allowed to run adapter brackets that come with every big brake kit on the market to get the caliper in the proper position.




I still think the EG and DC2 are the same, you can mix and match parts between them like legos.

Wait so the integra type R is legal as long as you don't use it's engine...

This is the coolest class in scca, but damn is it confusing.

Are we then allowed to run [brake] adapter brackets...

Sure, as long as you don't modify any parts on the car to install them. They're part of your alternate brake design.

Concur. We're doing what we can, when we can, to clarify it.

Cool thanks Greg!

I think your safest option for meeting GCR STL rules here to build yourself a 94 Civic EX/Si with ABS. It will still be 4 lug, but you will have a larger front knuckle (which BTW is the same as any non-Type R DC models), larger bearings, larger rotors/calipers (upgrade from 9.3" to 10.2") or get the Wilwood upgrade kit (11" or ~12.2") which needs the larger knuckle from the ABS model, larger brake booster and larger master cylinder. As tGA says, the Si/EX models came with disc rears, so that is an easier conversion.
