Sorry to post such a dumb question, but im ready to buy aftermarket rims and was wondering if i go 17inch up front and 18inch in the rear, what are the benefits of having larger rims in the rear? Does it add more grip, better cornering speed? Will i feel a big difference with the bigger rims in the rear ( like im being tipped). Sorry again, couldnt really find any info on this subject. Just need to change tires and wanted to get a completly new setup

Thanks

 

No benefit. You wouldn't feel "tipped" if you use the the same overall diameter tire, you would just have less sidewall in the rear. Some people like the look, it's more common on cars that come with staggered diameter stock like the Corvette. IMO, get a full set of either 17's or 18's, whichever you prefer.

 

Other than looks there would be no benefit. 1nate7 is correct that some cars do run the different size wheels like the Vette and the NSX. It would not hurt the car to go with the staggered diameter wheels.
If I can help with the package let me knw.

 

^ thanks guys! yeah i think im gunna maybe go the staggered route ill look around for some rims i like

 

You can do it, but only if you *like* the idea of spending ~$100 more for rear tires for zero performance benefit.

The look might not be exactly what you expect, either. When the NSX came on staggered diameter wheels, the tire diameter was also staggered, such that the front/rear tire sidewall heights were close to the same: 215/45-16 F, 245/40-17. Ditto for the C6 Corvette: 245/40-18 F, 285/35-19. (rear sidewall heights actually slightly taller).

If you run staggered wheel diameters with NON-staggered tire diameters (which you should do on the S2000), the rear sidewalls will be significantly (1/2") shorter than the front sidewalls, which can give a "big front tires/small rear tires" look.

Something to consider, anyway...

 

ooo thnaks, hmmm yeah there is a price difference, i think im gunna stick with 17" thanks Zdan

 

Stick with 17s.

 

Actually there might be some performance benefit to having the bigger rear. If you select a package on tire rack, you will see that the tires on the 18's in the rear also have half or an inch more width to the 17's in the front. That is very beneficial especially since s2k are rear wheel driven. That extra half inch or so of rubber will give you less slippage off the line and more traction in maintaining straight line acceleration through the gears. Not to mention more rubber to maintain acceleration out of corners .

 

Wat?

You can easily run a 275 tire on the rear with a 17" wheel provided you have the right width and offset. Diameter has nothing to do with it.

 

I did it so my Brembo's would fit. I needed 18's to fit the disk and caliper.
