Would going from 18x8 all around to, say... 17x8.5 / 17x9.5 be a loss of performance? Im dont give a damn about looks, I drive my car passionately, auto-x it and go to track days. The reason I dont go wider 18s is because of the price of the tires, I want a size were its not to expensive to replace tires 2 to 3 times a year. Has anyone done this, or seen this done? Please reply if you know what you are talking about, I dont want opinions I want facts.

thanks.

 

17x10 5 ziggen fno1 wheels all around with 275/40's and your set.

 

This combo is the "350Z Track Ho Standard" as they are cheap, strong, and fit over Brembo brakes

I have a set the 17x10 ET 25 and a set of 17x9 ET 35...great options for the track or street.

 

8.0 inches to 9.5 inches? I assume that would be 245 vs 275 mm tire? A superior 245 mm tire will outperform a poor 275 mm tire. So you get nothing with an addition 30 mm. That’s a fact!

 

Thanks for the replies, im going to look into the 5 ziggen....

 

5Zigen FN01R-C 17x9 +15 w/275/40 checking in...

 

Aren't the 5Zigens a little heavy for 17's - relative to RPF1's at least??????

 

FN01RC= good budget/decent weight
RPF1= more pricey/light weight

 

FN01R-C 17x9 is about 19-20 pounds.
