Correct, the lower the offset the further it will stick out from the fenders which can cause issue unless you are going for that look

 

While rays is a good brand there is plenty of other high quality wheel brands out there that allow for wider tires on a stick body S (well with rolled fenders).

For example

CCW, Work, SSR, Advan, Forgestar, etc etc. Rays are good but they aren't the only choice.

 

Its interesting to me and a little suspicious that most the out of the rather non conventional shit ive been saying about wheel widths/tire combos on this site for years before "urge" ever got involved, has been enforced by them now. I mean, if its true its true, the science is there, mine is reinforced by my own experience, but is just rather fascinating to see their attitudes and promotion about wheel/tire sizing evolve and then get mapped out on their website as hard fact since they arrived not long ago, like they pulled it right out of my Junky files. Makes me wonder if I’m dropping the ball on promoting some side business for myself. Instead I willfully give away everything I know for free as a time killer. If people/business is taking good knowledge from people/members on this website to help promote selling of their products, it is a little bit like stealing from the artist, and no one likes that when the artist isnt getting any benefit or recognition. Not saying that’s the case, just seems suspect at times

 

Tire choices in 17" sizes wider than 255 are extremely limited. A 255 tire can fit on the stock rear ap2 wheel.

 

Interesting read, thanks for this. I see 9.5 on the front and 10.5 on the back is the way to go but I still down understand what offset would be best?:

TE37SL 18X9.0, ET45
TE37SL 18X9.5, ET22, 35 or 40
TE37SL 18X10.0, ET20 or 40
TE37SL 18X10.5, ET15 or 22
TE37SL 18X11.0, ET18

 

None of these offsets will fit an S2000 in a 9.5/10.5 stagger.

You could do a 9 +45 all the way around, and or a 9.5 +40 in the rear but it will be very tight and you will have to make a compromise on running more then ideal aggressive camber for tire longevity. The other compromise/factor in either of these two sizes, is they can still only accommodate a 255 width tire, because of the rim width as well as how close to the fender these offsets run, so as we mentioned before, none of these wheels are serving your goal.

For a 9.5/10.5 width, and appropriate up size tire ie 255/285. You will want ideally a +55 up front and +65 in the rear. You can give or take 5-8mm on these offsets in these widths and still accommodate the tire sizes. If you up the rim width to another .5 front and rear, then your offset fitment gap closes and you need to be more exact - Especially if you decide to move to a 295 rear.

** Higher numerical offset IE +60 vs +40 the closer it is to the inside or vice versa (in MM)

**The width of the wheel gets split down the centerline based on the same offset. So 1" wider wheel at same offset gets .5 more inner and outer, shortening the clearances on both sides. Make sense?

I get it now, thank you! So apart from being 18" there is no real gain with the rays but .5 of an inch at the front. I will have a look around for other wheels with bigger offsets
