Fist timer here, want to sign up this summer.

I have a suspension/chassis modified challenger R/T stock motor 6 speed. What would be the best class for me?

CAM-C. Just make sure you have 200TW (or higher) tires.

Hi I have a stock 2019 VW GTI rabbit edition with DSG transmission. I looked at the rules pdf and it says "GS"?

I have a 2019 fiesta st. The only mods I have on it are lowering springs and camber bolts. What class would I be in? Also this would be my first autocross

Ben, your car would be in HS is you ditched the springs and camber bolts (and it'd be very competitive to boot!). Otherwise you'll slot into the STH street touring class or you can run in CST, our open catch all class.

For future reference, here are the SCCA provided stock car classing guidelines, to use these first identify the street (or otherwise stock) class your car resides in.

If you have any mods, check them against this handy spreadsheet that shows the allowances for the other prepared/modified classes.

https://www.scca.com/downloads/44544-20 ... s/download

If you have mods that bump you into an alternate class (say lowered suspension which would move you into at a minimum Street Touring or ST) then you'll need to check the full SCCA rulebook to verify which class your car falls into.

(This file is a .pdf so ctrl+f and search for your make/model to easily find what classes its eligible for!)

Hi guys, i have a 2013 370z Nismo, which i know is in the STU class, but i do have Cold Air Intakes, ArT Test Pipes and a Catback Exhaust System. I am also upgrading rear diff bushing to stiffer ones, and may tune my car soon. Will that kick me into a different category?

The tune and the bushings are all Street Touring legal, however your test pipe will automatically bump you up to Street Prepared (SP). I would just run STU for now, you can ask your competitors if they are ok with it as the test pipe will only give you a slight power advantage, running in SP will be brutal unless you have Hoosiers :D

Hello all! I have a 1995 BMW 318ti that is stock except for a welded replacement muffler past the rear axle. I checked the rulebook and my search only showed F Street prepared. Can I possibly get more clarification on what class I can be in? Thanks! Your assistance is greatly appreciated.

Pg 195 in the 2019 rule book shows a stock 318 would go in H-Street
