Anyone out there know what fits for a stock class 2006+ Civic Si? Also interested in recommendations for stock size autocross only wheels. Finally any setup advice will be appreciated.

 

Sell it and get a Cooper S?

 

I've seen an Si do good with 215/45/17 (I think, maybe it was 225) hankook Z211 on 17x8. It was on a low to medium speed track, but not solo2.

Civic Si is a stop gap until the Boxster project is ready to go. I know we will get clobbered by the Coopers.

 

how about..

What's the stock wheel size?

Stock tire size and outer diameter?

 

Alan, SSR's or Enkei RPF-1's. I'm assuming the stock wheels are 17x7?

Hoosier 245/40/17's up front, 225/45/17's out back. w3rd!

According to the Tire Rack website, Honda used two wheel and tire sizes on the 2006 Civic Si. The sizes and calculated OD are:

215/45-17 - 24.62"
215/40-18 - 24.77"

Summer tires were an option from the factory; like most Honda factory options, they actually consider the summer tires as a separate model. I would assume that the 18" wheels and tires are the summer tire option, and the 17" are on the ones that came with all-seasons.

 

Thanks Nate (I think)
