Tire rack has the Kosei K1 is 45 and 38 offset.

I am running 205/50/15...

If I ever wanted to go to a 225, which offset would be ideal? (I know Ill need 5mm spacers)

The 38 is $139 and the 45 is $119

 

I'd go w/ the +45 offset.

 

 

is it 15x7? then, go with +45mm offset.

 

THANKS ALL!

I just ordered them!

 

Erm.

Are you SURE you got 45mm?!?!

I think they will send you 43mm. I am pretty sure hat Kosei does not offer K1's in 45mm for our cars. 38mm will let you run 225.

Personally, I run 43mm all around, and use 5mm spacers in back, bringing me to an effective 38mm offset in back.

I just got the k1's on sale from tire rack a few weeks ago... offset is 45mm. I double checked both the paperwork and the sticker on the inside of the rim, just to be sure. and yes, this is for an ITR.

 

I plan to run the 225 later... but I guess Ill need the 5mm spacers.

I planned on getting them anyway.
