Hi all,

I've got a 2001 S2000 that I use for my daily drive. I'd like to put on Enkei RPF1's (which I know a lot of people here use), but it doesn't look like they make them in the correct size for my existing tires (they list several 16" options on their website, but nowhere my tire guys or I trust seem to carry them). With this in mind I thought about upgrading to 17" wheels, but after calling around in the local autocross scene people have mentioned that they're notorious for rubbing the rear fenders on S2000's at that size.

So my question is simply, what did you do to get yours to fit? Extremely thin tires? Modified suspension? Or do they make a 16" version in the right bolt pattern?

Any tips, advise, tire/wheel specs, fender or suspension modifications, etc. would be appreciated.

EDIT: I should clarify that my suspension is stock, and I'd prefer not to roll my fenders if I can help it. I'm running BFG Comp2's (P205/55ZR16 and P225/50ZR16) and would love to re-use those as they still have a ton of tread on them, but it looks like I won't be able to.

You will have to roll your fenders even with a standard 17x8/9 +45 setup. There are several members that have stated they run a slight stretch to avoid it, but unless you're staying stock height I'd advise against it.

A couple factors here:

1. Tire width
2. Stagger or non-staggered?
3. Alignment - negative camber is your friend
4. How much fender work do you want to do?
5. How low are you?

I ran 17x9 + 45 with 245/40/17 at all corners with significant negative camber and only a front fender roll. With a 17x8+ 45 up front, I would think it would be possible to run the setup without any fender work. Keep in mind the faces are different on the 8 vs. the 9 but I like the look as well.

There is an RPF-1 thread on here for inspiration, a lot of people posted their wheel specs.

Definitely staying stock height for now, but I think I'd rather not run stretched tires if I can help it.

1. I updated the original post to include my current tire specs (but I'll have to change those, of course).
2. I don't really know how this will affect handling; from an asthetic perspective I don't really care though.
3. I'm currently running -1.0 all around, but I think I'd like to increase (decrease? I hate saying "increase negative camber") this to about -1.5 or more.
4. I'd like to do none, but I'm starting to realize that this might not be an option.
5. Stock height; no plans to lower it any (looks good lowered, but I like being able to go over speed bumps, and my neighborhood is full of them).

I've been looking at the RPF-1 threads; seems most people leave out just enough info that I can't tell how they got it working though (or have something that will obviously rub over even small bumps, but don't mention it). Still digging through them though and hopefully will find something.

Thanks all

Problem is no one can guarantee you it is going to fit. Best bet to fit it with stock fenders would be to try running:

17x9+45 rear with 245 tires
17x8+45 front with 225 tires
at least -2 camber all around

At stock height, I don't think you will have issues.

Changing to a 17x9 front and rolling the front fenders will mean more grip up front. More grip up front means more oversteer - so be ready to look into larger front sway bars if you go this route.

Bellow is a size chart of what Enkei offers in the RPF1. If your goal is simply function with minimal to no hassle/no fender modifications then I would recommend you go with the 17" - 7.5" + 48 up front with a 215/45 an a 9+45 with a 245/40 in the rear. This would be the proper up size for your car/same as ap2. This tire width bias also maintains the traction F/R bias of your MY S2k. If you want to keep it simple stupid and simply slap them on, this is your best choice. I do recommend you get an alignment with additional negative camber in the rear, it will perform better anyway.
-1.8-2 would be great for the rear. -1 to -1.5 up front would be safe. Wile your at it. Run Zero toe up front and the least OEM toe in the rear. This will maintain great tire longevity.

So it looks like my options are:

17x9+45 rear with 245 tires
17x8+45 front with 225 tires
at least -2 camber all around

or

17x7.5+48 front with 215/45
17x9+45 rear with 245/40
~-1.5/-1.8 camber

A bit more negative camber is something I was planning on doing anyways, so this is good news. Thanks for all your help; I'll send these over to my tire guys and see what they think would be best. Thanks again.

EDIT: Actually, would the +45 on the rear not stick out past the fender and require some fender rolling? I'm not very experienced with wheels and tires; but this does seem like it would be too much offset. Maybe not though.

My rear fenders are 100% stock with 17x9 +45 and 245's. I have -2.5 rear camber and quite a bit lower than you are and it fits fine. 10mm more though (255) and it would rub for sure.

Yep, and OP keep in mind your going to get more camber naturally as the suspension compresses, since your at stock ride height you have a lot of suspension movement/tuck before you get to your fenders.

Also keep in mind that running a 225 paired with the 245 in back will change how your car handles and looks. The 225 is a taller tire then the 245. The 215/245 combo is the correct one if you care about the original bias. The other option is to run the 8 +45 up front and stick with the 215, it will be slightly more stretched but that will also help with fitment, you should still be ok with stock fenders with more camber as you were considering. The reason I offered to suggest the 8" wide up front as an alternative is because the 225/45 would better fit this and mate up to a 255/40 rear if you ever wanted to run this out back and roll your fenders. 225/45 will fit on the 7.5" but it will be a bit pinched which isn't as ideal for handling precision and feel.

im on stock height with 17x9 +45 all around with 255/40 rears and 225/45 fronts no rub anywhere
