If you have a stock MCS then you can run in G class.
You can use 16x6.5" or 17x7" wheels (as long as it does not have an offset more than +/- 0.25 inch from a standard wheel for the car.)
What is legal?
Any stock size drop in air filter-no cold intakes
Any front swaybar- no aftermarket rear swaybar
Any Cat-back exhaust (edited)
Schroth harnesses.

From the cat back. Ya can't touch the cat or forward from there. In other words, no new headers to the new exhaust.

Yes, no exhaust header.
Sorry I corrected my earlier post.

 

Word. I was pretty sure that's what you ment, just wanted to clarify for the masses.

Also, you may run any DOT-approved tire that fits the stock size wheels. That includes Hoosier and Kumho "R" compound (read way more sticky that street rubber) formulated tires.

Other allowed modifications include Ignition Wires and Coils, spark plugs of your choosing and a harness so you can use the steering wheel for its intended purpose and not additionally as a "Jesus Bar".

You can also add aftermarket shocks, which I strongly recommend. I don't usually Auto X my MCS but I have a lot of experience Auto Crossing, I've Auto X corvettes for years.

Good Luck,

baronius,
Thanks-that sums up all the requirements and rules.

 

Just bear in mind that some clubs restrict tire choice, especially if you are just starting out and running in a novice class.

With Gulf Coast Autocrossers in Ft. Myers, for the regular stock classes you can use any SCCA approved, D.O.T. approved tire that will fit on a stock sized wheel, including R-compounds. But to run in the Novice category, they specify 200 treadwear or better and no R-compounds. This effectively eliminates the Hoosiers and Kumho race tires. Their thinking is to keep the costs down for people just starting out and to help new autocrossers learn car control.

Thus, for Christmas I got lightweight Lucca Nikko (SSR copies at 14.3 lbs but 1/3rd the price.) 16"x6.5" wheels and I bought 215-40-16" 200 treadwear Falken Azenis to put on them. This allowed me to remain in the novice class for this season. I have the factory 17" S-lite wheels and Dunlop 9000 sport run-flat tires for driving on the street. When I weighed them, the 17" S-lite/Dunlop combo was about 46.5lbs, while the 16" Nikko/Falken combo was 38lbs a corner. I figure I saved around 32 pounds of unsprung weight. There was a much greater choice in tires going to the 16" wheels, and the wheels were much lighter. After participating in four events with the factory wheels and rubber, they are shot with only 12,000 miles on them. In my first event this season (yes, I'm in Florida where it's not too cold to autocross in January) I found a tremendous difference in the Azenis, and feel they really helped. Also, they didn't seem to wear nearly as fast as the stock rubber.

Where did you find the Lucca Nikko wheels? I have not heard of them before and am definately interested.

 

Go to http://www.aktiresusa.com for the Nicco's. They have them in both 15" and 16" sizes. They are located in Tampa, Florida. I haven't delt with them over the internet, I went directly to their shop.

Also, one of the sponsors of this forum, Webb Motorsports, offers these exact same wheels under the Monza name.

How much $ for the AK purchase?
Thank you.

 

They initially quoted me $449 for four of the Nicco wheels in silver finish. Some of the other finishes are slightly more. I paid just over $1,000 as a package for the wheels, Falken Azenis tires, mounting, balancing, and FL sales tax. Without the tax, it would have been under $1,000.
