I'm working on a K24 engine, and am thinking that traction may be an issue with the stock 15" wheels. In looking at affordable forged wheels, I've come across JDM BBS s2000 wheels.

They are the same size and offset as ap1 s2000 wheels, except forged and six-spoke.

Would running the 7.5" on the front and the 6.5" wide on the rear be a good idea? Anyone ever run these wheels this way before?

I already have extended lugs all around, so running the proper spacers won't be a problem.

Or I've also found a set of 4 rears from a guy who autocrossed his s2000 for sale, would it be a better idea to run the 7.5" wide wheels all around?

I have a set of 4 piston RL calipers I'll also be putting on, so brake clearance will be a concern and another reason I want to go to 16" wheels (should be able to fit 12" rotors under them).

 

IDK but the width and stuff, but I love those wheels. I was going to buy them but couldn't find 4 fronts.

 

When running S2K rims on an ITR, Only the fronts fit. The rears will rub and cannot be used.

OP, you will find more suitable options elsewhere.

 

Supposedly this car has S2000 fitment on it: http://www.integratyper.org/usdm/rid...2/01xxxx-2.htm

I don't know her login name on here, but I'll send her a link to the thread in case she has a sec to comment.

 

you can only use the fronts, the rears have different center hub sizes and dont fit the itr correctly

 

OP: If you don't care about being extremely low you shouldn't have any issues fitting a 7.5" wide wheel up front.

I do have S2000 fitment Regamaster MP wheels on my ITR. They WILL fit, although the center hub size has been drilled out on rear wheels.

F:17x7 and R:17x8 with +45 offset Tire size: 205/40/17

The car is not low by any means and I am running 3 degrees of camber in the rear. The car is not daily driven.

Hopefully that is a little helpful!

 

Thanks for the info, I guess I should clarify, I'm not asking if these are a 'bolt on and go' affair. I know they're not.

My plan is to run a ~25mm spacer in front and run the rear s2k wheels. 16x7.5"+65 is the standard wheel spec, so with the spacer it should be closer to a +40mm offset.

I can either get a set of 2 fronts, 2 rears, or a set of 4 rears.

For the rear, if I use the front s2k wheels (16x6.5+45) I'd add a 5mm spacer, and if I end up getting the set of 4 s2k rears would use a 25mm spacer.

Also, my front fenders are rolled slightly and my rears are notched out for wheel clearance, as I previously ran 16x7 +32 wheels all around with little camber correction.

I'm thinking this should work, it doesn't sound like many have tried it though. I think I'll end up buying the four rears, I run a pretty stiff rear sway and I don't think I'll need help rotating.

 

buddy read, the rears wont work, you need to have the center hubs bored out, the rear s2k wheels have different center hub bore's then the fronts

 

Buddy read: "I'm not asking if these are a 'bolt on and go' affair. I know they're not."

I have no problem with reboring the wheels' hubs, also, a spacer with the proper hub bore would work fine without needing to touch the wheels.

Eff it, I'm buying them. I'll post pics when they're on the car.

 

hub bore shouldnt matter of youre running a thick enough spacer right??

 

Right on.

 

This doesn't make sense to me. The only reason to drill out the centerbore (that's the proper name of the big hole in the center of the wheel) is if it's SMALLER than the size of the hub. That's not the case with any S2000 fitment. S2000 wheels have a 70 mm center bore in front, 64 mm center bore in the rear. The ITR wheels have a 64 mm center bore. So there should be no need to drill them to make them larger. However, you ought to consider getting some hubcentric rings (or a hub adapter which replaces the studs and provides a lip like on the hub) if you decide to use the S2000 front wheels with their too-large center bore.

Also note that if you want to use the 16x6.5 front wheels from the S2000, you will be limiting yourself to 205/45-16 tires; the 215/45-16 size also used on the ITR shouldn't be mounted on wheels that narrow.

Buddy read, there's no need to have the centerbores on any of the S2000 wheels bored out; even though the rears have different center bores than the fronts, neither one is smaller than those on the ITR. See above.

This is a serious concern. If you are using one of those flat metal plate type spacers, one that is thick enough that it pushes the wheels out beyond the hub, then you lose all hubcentricity, and only the lug nuts are centering the wheel. There is then a serious risk of vibrations without any hub centering. Some people luck out and don't encounter any problems with vibrations, but many others experience serious vibration problems, even if they do all the right things when mounting the wheels. I have quite a few friends who tried using those spacers and never could get a vibration-free fitment. Some of them sold the wheels off. Others ditched the flat spacers and instead bought hub adapters, the kind that come with a lip over which the wheels fit for hubcentering (such as these).

All of these concerns and issues are why, as Shawn noted, it's just a whole lot easier to get wheels that are already designed and sized to work on the ITR without any problems or need for workarounds.

 

Thanks for all the info NSXtasy.

I thought that the centerbore was oversized, but couldn't remember.

I will be running H&R spacers, I also don't trust the flat plate style.

I realize there are easier options, but I'm getting these wheels at a price that makes them seriously worth a look. Much cheaper than any other forged lightweight wheel would cost, and I have to admit that I like the design to boot.

I'll update in this thread with issues/solutions/progress. I will also be machining a bracket to utilize 4 piston RL calipers (another reason for the wheel change), which I'll hopefully create a thread on in the brakes section.

 

Right nowI am running a set of the 16X6.5 s2000 wheels. They fit fine with a 5mm spacer in the rears. The problem is that I painted a set of wheels (16x6.5 and the 7.5's) but I can't use the rears unless I have the correct spacers. so as of right now, there are 2 different sets of wheels on the car. I'm not sure which spacers to use in the rear.
I just dont want it to rub the rear quarters. I saw you guys were using 25mm spacers, is there any rubbing? I am using 205/50/16 tires (i know theyre stretched a bit). I would like to get 20mm spacers but I'm not completely sure if that would be thick enough.
Any help is appreciated.

 

I had 4 front S2000 rims on my R and the only thing about it is when u are around 70 or more mph the steering in loose. might want to keep that in mind.

 

they dont look right at all.

 

the problem isn't the wheels, s2000 don't feel loose a 70 mph+

 

There were no cons in installing these wheels, the car is more responsive and the ride is smooth at any speed.

 

Wow, wrong tire size and problems with the wheels.

 

i meant performance wise

 

There are no performance benefits to using too-tall tires.

 

Alright, I F'd up and I'm sorry. Can we get back to the spacer suggestions please?

 

I don't understand the benefits of using the S2K wheels when so many items need to be addressed to get them to work properly.

It's not like they are all that light nor are they all that good looking. Plus, the fronts are only 6.5" wide. Heck, OEM RSX wheels are a better choice as they are 16x6.5" +45 and only weigh 16lbs.

If you must have OEM, why not just buy a set of JDM DC2R wheels that are 16x7 and bolt right on? No offset issues, no hub issues, etc.

Sometimes people go to far to make something work and just end up with an inferior product in the end.

 

for all the trouble I would just get four nsx front 16's, they look amazing on itrs
