I am going to autocross my wrx and I found a set of tires that is 245/45zr/16, I want to get light racing (only for autox) wheels will they fit under the wells? Also anyone know where to get good racing wheels?
ThankS

It depends how much you want to spend. 16" Volks are ~11lbs, but they're also $400 a piece.

Subydude was selling some 16" Rotas awhile back for cheap. Not 11 lbs., but lighter and wider than stock.

Those are the Rota Slipstreams in 16", I got a set from Subydude and they fit and look nice. Weight is 13.5 lbs.
I believe he may still have a few sets left, get in touch with him if you are interested.

the dude also came out with the rota grids..you might want to look into that

I found a site selling Rotas and the weight for 17" Battle wheels was about 16.5lbs. That seems a bit heavy (I have read people talking about ~11lbs). How do they compare to the stock 16"?

How much do the stock 16s wiegh?

Also, how do they compare to the BBS wheels? As far as I can tell, BBS makes 1 WRX wheel, the RK (http://www.bbs-ag.com/cgi-bin/nach_pkw_04_e.pl)

These cost about $230.

How do they compare?

Thanks,
