Hi. I'm about to purchase a set of Kosei wheels (17x7 all around) and was wondering if 215/40/17 would fit. The car is currently stock but i will probably be doing suspension modifications in the future. Thanks!

 

What do you want to do with the car?

Many with Gen 1 like to with with 215/40 17 series to get better gearing and to make better use of the torque curve from the supercharger.

Many with Gen 2 will go with the 215/45 17 as it has better torque.

Your call.

Just an aside, the dunlops z101 is not a great tire choice.

 

Sorry i actually meant the Dunlop Star Specs. I ran them on my old E46 and loved them. Don't think you can find a better bang for the buck tire than them. But anyways my car is a Gen2 so i'm assuming the fitment may be different or not by much? Also I'll be using the car for my daily and a few de's throughout the year.

 

I do about 15-20 DEs on my DD a year on my R56 and prefer the 215/45 17 size.

I like Dunlop Z1 star specs but you should not run them on the track at full thread because they will chunk. I use them now mostly as a wet tire.

 

Thanks for the advice. Guess i'll order them when my tax return comes.

 

Not sure where you are located but if you are in the NE USA, please join us when we run out to the track.

 

Unfortunately i'm in Norcal.

 

A little too far. Have a great time at the track.

 

I really like the 215/40-17 size. It looks perfect

Btw: there is an all MINI track day at Thunderhill Raceway at Willows, CA
