SCCA A/X rules questions about class and OE stock vs mods, main question is about tire and wheel size changes Options

[DRPHIL914]

I was online looking a local events and trying to find some A/x events in the
South Carolina or North Carolina region,(i live in SC near Savannah Ga, but my son lives in Charlotte and we frequent the area)
Anyway i found out on i thing the event list on Motorsportreg.com that there is a regular A/X events up in Charlotte region, and took a look at the rules and classes etc, and was wondering if anyone here was doing that up there or even somewhere else could guide me in the registration process , and, answer some questions about if i can run the tires/rims i have or do i have to purchase other wheels to run the proper class.
In the rules and class descriptions i notice they say you have to run rim size and width that would have come on that model for the year?? but what about diameter etc too?

My 75 914 has the stock 2.0 L motor all original and stock, except i did the PMB Performance 5-lug upgrade with stock rotors and calipers etc, i currently have 16" fuchs rims with 205/55-16 tires(that are same diameter as a stock set up but much wider) i have 6" on front and 7" on rear. So my question is , to run in the stock un modified street class would i have to source a set of 15" x 5.5" rims for the A/X? I could do that they would then be same size and width as the stock rims that came on the car, just would use 5 lug rims not 4, but that should not matter as long as i have same specs.
I just dont think i want to be bumped into a modified street class just because of slighly wider tires, so please advise.

thanks for any infor and direction you can provide.

Phil.

Hi Phil
A lot will have to do with the sanctioning body....SCCA, PCA,etc...
Some groups will be happy to have you regardless and others will be sticklers on the "letter of the law".
Either way you should go and have fun. I spent many years doing it and had a blast.

Play ignorant.. sign up for the "stock class".. and wait to get yelled at later (IMG:style_emoticons/default/wink.gif)

Unless you are running for an SCCA national championship, or you go up and beat everyone, no one will really care. Miata's will rule the roost in any class it seems. A 914 will do best to simply not be last (IMG:style_emoticons/default/wink.gif)

Does the registration link have an email you can ask questions to? like the event host?

thanks for the responses! yes, i think i should be able to email them but , i like the
better to ask forgiveness than permission approach too (IMG:style_emoticons/default/rolleyes.gif) (IMG:style_emoticons/default/happy11.gif)
but i may still scout out some 5 lug 15"x5.5" rims just in case too. Hard to find, either are the difficult to find fuchs that size or Mahle that are god-awefull expensive. I know there are steelies that were that size, and maybe some minilites or other aftermarket brand as well.

I have an extra pair of 16''x6'' fuchs i can offer up as partial trade too. then my next question will be best tires. I have some Firestone Firehawk indy 500 summer ultra-performance that are z-rated and are @280 on the hardness, so pretty sticky, those are on my current 16" x 6" and 7" Fuchs
