To anybody that can give me advice:

I am planning on buying a set of wheels for autocross, and will be putting BFGoodrich gforce T/A R1 Tires.

My question is as follows what size wheel will be better suited for Autocross????

Thanks

AEC, I think you need to tell them what modification class you intend to run in.

If it's for stock, I think somebody mentioned that the lightest wheels available in a legal size were 16"-ers from the Mazda Millenia. What year, I'm uncertain. Eventually I'll look into what can be had from Japan.

If you're going to run in stock (Which for the IS will be DS for 2002), you are limited to the available factory sizes +/- .25" offset. This means you can run the factory 17x7 wheel or the 16x6.5 wheel or any aftermarket wheel of eithe size with an offset difference from stock of less than .25"...

I run the 16" wheels for two reasons. They were cheap and there were better tire sizes available in 16 for that wheel width. (I run 225/50/16) Also, all things being equal, the smaller wheel should be lighter and, of course, smaller.

I'm getting back into Solo II after a 4 year absence.

Tony, What brand wheels and tires are you running? Looks like BFGs are going to be the cheapest from TR. I really hadn't considered running the 16x6.5, but you points make a lot of sense.

Of couse looking at TR, I'm not seeing the BFGs in 16" sizes. Hoosiers and Kumhos are much more expensive. Last time I was in this game I ran BFG R1s and was very happy with them. Of course that was a 2500lbs FWD. I can see the Hoosiers and Kumhos being better on the IS300, but look at the price difference (price per tire):

BFG R1 - 205/50/17 = $70
BFG g-Force R1A - 205/50/17 = $49
Hoosier A3S03 - 225/50/16 = $173
Kumho V700 - 225/50/16 = $129
Yoko A032R - 225/50/16 = $139

I could see saving money on the wheels if I could get the BFGs in 225/50/16. I'll have to look into this more.

I'm running stock SC300 wheels, cost me $250 for the set of four - and Kuhmo V700's, though they're pretty much dead now.

The BFG's have been discontinued for over a year and that is why they are cheap. These tires were known for quick wear and tricky handling. These are the next generation after the original 230 compound R1's.

Hoosiers are probably the stickiest, but are past their prime after about 5 heat cycles.

The Kumho Victorracer V700's are a bit slower than the hoosiers, but wear better and last more heat cycles. They are usually good right until cord and most people get over 100 runs on them

The Kumho Ecsta V700's are the newest tires from Kumho and are not available in many sizes yet. These have better turn-in and are crisper feeling than the Victorracers. From the wear I'm getting from these tires, they should last atleast as long as the Victorracers. I'm not sure if these are as fast as the Hoosiers, but are atleast as fast as the Victorracers.

Hope this helps.
