Default Best wheel size for autocross

What is the best size? I just sold my 17's and I am getting ready to buy 14-16" wheels. I am not sure if I want to go with 16's because of tire price and I don't have plans to do bigger brakes anytime soon. <--Is that really necessary?

I am looking for a cheap, multi-functional wheel size choice.

Thanks!

It's for an Integra DC2.

I think this depends on how competitive you are. If you are doing autocross for competition (like you're going to nationals), and you are getting purpose-built autocross tires (like the Hoosier A6), then you probably want to get a wider size than you would if you were using these tires for the street as well, and didn't care about every last thousandth of a second. Given your note about "multi-functional", I assume the latter is the case (that you're not competing strongly). I would recommend getting 15x6 or 15x6.5 wheels, either of which can be used for street tires (195/55-15 or 205/50-15) as well as R compound tires (205/50-15) for your car. One common tire for street and autocross use is the Falken Azenis RT-615 in 205/50-15; because it's bigger than most other tires labeled that size, 15x7 might be a better choice for that particular tire, but 15x7 is a bit wide for most street tires, so I would suggest 15x6.5 if you plan on using the Azenis (or R compounds), and 15x6 (like the stock wheels for the GSR and Type R) for any other street tires.

If it's an Integra Type R, you don't need bigger brakes.

If it's a GS-R, it depends. I suggest just going out and using your stock brake calipers, with a higher-performance brake pad and high-temperature brake fluid. If you find that you are still overheating your brakes, THEN consider getting bigger brakes. (But I bet you don't need them.)

I guess it must be a GS-R, since you would never consider putting 14" wheels on a Type R (they won't fit).

Thank you nsxtasy

I think I will go with the 14's because (you've seen my road race thread) the tires are cheaper and the wheels will fit my car. I don't see myself upgrading brakes (bigger brake kit that is) anytime soon because I don't think it's necessary at this point. I am going to send you a PM if that's ok
