What size tires should i get for AutoCrossing?

IMWEZL

You might want to check what class you will be running in if you change your wheel size. I think you maybe able to stuff the biggest tire you can onto the stock rims but changing the wheel size usually throws you into a different class.

I think the Z is now in CS...used to be in BS. I know BSP in Hawaii was insanely competitive.

Since you're just starting off in Auto-x I would recommend staying stock for at least one whole season just to see where the limits of the car and your driving skills are at.

Other than that have fun!

Yep! i had a long talk with quite a few very helpful people and although im actually on hold due to a family issue needing the money i set aside for the wheels, Ill be waiting either way. For now i am going to upgrade suspension, sway-bars, and brakes but keep stock rims/tires for the first few months so i dont screw my learning curve. If anyone else is looking to do what im doing i can quite happily recommend having a chat with Scott from Relentless Autosports in CA.

Also! A big thanks to everyone who contributed to this thread and the others ive posted along the same lines

I am sorry, but you are doing it completely backwards. You should do tires before you touch any suspension pieces. Suspension won't do you much good if your tires are stock, there is a reason why BS and CS classes are faster than most ST classes.

My car has 1900 miles, my suspension is all stock and I bought my RE11 at 700 miles. It's working out pretty good so far as I can hold my points lead

Scott @ RA

What I understood after talking directly to Mozen is that he is looking to get more into REAL track days, HPDE's, and some sort of Time Attack and time trials, etc.
Autocross is one thing, but actual track events are completely different.
Brakes become MUCH, MUCH more important when tracking... not only from a performance and repeatability standpoint, but more importantly from a safety stand point as well.
Suspension (ie: sway bars, coilovers etc) also become increasingly important when tracking, compared to coned off parking lots. There is MUCH more speed and corner speed carried on tracks and the need for better brakes and suspension vs tires goes way up when dealing with the higher speeds.

Although in steps, I would put proper wheels and tires right up there as a very close third on the to-do list, right under brakes and suspension.

If he is talking about track, all he really needs to start is a set of brake pads (XP8 or XP10), brake fluid flush and some decent tires. Once again, there is no need for any major mods before the driver. I won a Redline Time Attack with a stock vehicle on Run Flat tires (street class) against many highly modified cars. I do highly recommend changing brake pads and fluids as a safety precaution. The OEM rotors are 14", please don't tell me you have to get Wilwood.....

R comps are probably one of the worst thing you can put on a novice driver. They usually release grip with no sudden warning, it's usually not recommended unless the driver could handle it.

315 or 335 might be nice for autox, but they are overkill on the track as they scrub way too much speed. Also that would mean going to a Hoosier.

Im not going with a crazy BBK. After talking to people who race for a living like Scott and then a few of the guys in my unit im only upgrading my Brakes to the sport package Akebonos, ill throw SS lines on there, Correct Pads for Track or AutoX depending what im doing and better fluid.

Since i want to, ill upgrade the Suspension, throw in the whiteline sway bars, Intake, Exhaust, oil cooler. Just about everything else im doing the the car is for safety. (4 Point Roll Cage, FIA Seat/Harness(HANS device compliant) HANS Device and helmet. For the SCCA events ill not change out my stock summer tires but when i go to the track ill throw on something different.

That all said i still have 8 months until this deployment is over and i can spend some serious time driving both at the local track and our airfield for army/scca events.

That gives me plenty of time to decide what i want to do, spend or save money and so on

Im still open to feedback and ideas although it does seem like the topic has changed :P perhaps i should nix the thread?
