Question on Enkei Kojin Offsets et35

Narrowing down my wheel choices when I get my nsx. I am looking at the kojins and I want to run 17x8 fronts 215/40/17 and 17x9 rears 255/40/17. Looks like et35 on all 4 corners is a nice setup. See any issues?
TIA,
Kevin

17x8 +35 fronts will probably cause some rubbing issues on the fenderliners, but it'll be pretty flush.
Personally I would do the 17x8 +40 to give you a little extra room.

For the rear I would do a 18x9.5 +30. I think it'll look a lot more balanced than the 17x9.
 
They don't make 9.5 in the 17.

If you do go to the 17x9 35 setup, you should not do 35 front. It will stick out more than the rear and it may rub depending on your camber and how low you are. However it will give more big brake kit clearance. So take that into consideration. It will work, you just have to fiddle with ride height and alignment settings, it will sit very flush. The front should then be 40 or even 45 to balance it but both front and rear will sit in just a bit. Not as much as OEM but still inset.

The size you really need to be going with is an 18 rear. Your setup should be 17x8 ET 40 front and 18x9.5 ET 30 rear. That will really balance things out and look good. Take my word for this one.
 
Let me toss the qualifier in there that if you're going to track the car, plan to go through a lot of rears, and you have a budget of any type, the 17 rear, as long as it has a good concave shape, shouldn't look too bad. The premium for 18" tires is retarded.

I'm looking at the Kojin in 17/17 myself as a track wheel for that reason.
 
Not a bad idea R13. My real question is what will these clear for a BBK.

Great info! And words of advice for if you subsequently lower the car a bit via Bilsteins?
 
I'm running 17x8 +35, and 18x9 +30. Min rubbing up front and I'm pretty low. Check my build thread.

Thats a very conservative lowering I think you should be fine. But I would really consider jumping into a set of BC coilovers for a little more. You have so much more flexibility in terms of lowering, adjustment, rake, corner balancing, etc. I mean its like $400 more I think? its worth it.
 
I'm wheel shopping too, and appreciate all the good advice here. However, just to be clear, will the 17x8 +40 / 18x9.5 +30 combination (along with the recommended 215/40R17 and 265/35R18 tires) work with the stock suspension height without sticking out of the wheel wells? I ask because it seems many, if not most, of the cars seem to be lowered, which I understand pulls the wheel inward. The car is plenty low enough for my liking as is, and I don't want to lower it. Thanks!

I am QUITE concerned that a 9.5 +30 wheel with a 265/35/18 will stick out of the wheel well on a stock height NSX.
 
18x10 at et 35 clears no problem why are you concerned with a 9.5 et 30? 1/2" is almost 13mm, 50% of that width is roughly 5-6mm. The et difference is also 5mm why wouldn't they sit the same?

I'm not saying I'm going to impose my opinion on everyone and go 9.5. If people want 10 we get 10. But I don't see the issue with the et30 9.5" wheel. I think synth19 is using 18x10 et35 and added a 5 spacer.

What you are missing is the huge difference between lowered and stock height (which is what the OP is wanting to run)

Also, the difference between a 9.5 and 10" wheel is that the tire will still sit in the exact same position regardless of the rim width - i.e. the 9.5" et30 wheel will put the tire 5mm more outwards than the 10" et35.

And Yes, synth may be using a 18x10 et35 with a 5mm spacer but his car is very low which allows for the aggressive offset.

Remember I am also using a 19x10.5 et29 but my car is very low too.

Wow... I am running an ET25 wheel and I am clearing. Might have a problem with a wider tire though not sure... I am using a 255 now.
 
Soooo....I'm still confused and don't want to screw this up. Let me ask it this way: What would be the specific offset (I assume whether it's an 18" or 19" rim diameter wouldn't matter) that would enable me to run he widest tire (I'm open to suggestions) on the rear of my '95, assuming I run a 215/40R17 or 215/35R18 front (depending on whether it ends up being a 17/18 or 18/19 combination), on stock height suspension? Thanks!

19x11.25 +48 with a 315/25/19 :eek:

Now is 315 practical? No. I wouldn't go larger than a 275/30/19.
265/30/19 is another suggestion.
 
Here is a data point for you.

In preparation for the NSXPO track days, I just put on Enkei Kojin with Yokohama Advan AD08 R in the following sizes:


17x8 et40 with 215/40R17
17x9 et35 with 255/40R17

This is on an otherwise stock '97. This is the result:

Ok so what sizes would you run in a 17/17 and you wanted to run NT01's in 235/275 do NT01's come in 17's in this size for the rear? or would you stay 18 in the rear
i currently have this similar setup below with Dunlop Z11's but want a track dedicated rim with rubber to match but maybe with the 17 rear not the 18 as i have now.
this is my current config with OZ rims
17x8 et40 / 18x9 et35
Tire size f/r: 215/40/17-265/35/18

I went with 17" rear because it seems like there are more tires available for that as compared with 18". That's particularly true if I wanted to stay with 255 width in back.

I understand that the 235/275 combo will rub if you still have fender liners. But if you like that size, the NT01's do come in 235/40R17 and 275/40R17. Your current tires seem to be smaller in diameter than stock as you're running one aspect ratio lower.
 
I know i am sort of jumping this thread but my current sizes and offsets are what the op is after i have run that combo for years with no issue.

jwmelvin nice car too by the way, would you keep the same size wheel and offsets with running the 275 NT01's or would you need to go to 10 in the rear since they dont make a 9.5 to take the larger tire? (do they make a 17x10 et35)
I have the wider from factory front fenders and no BBK just a 97+ brake system the car is lowered and this setup would only be for at the track i would revert back to my other rims and the Dunlops for daily use so rubbing would not be as big a issue and i am working on some more neg camber up front.

Only up to 9" width in the 17" diameter.

The nitto NT01 you want is specified for wheels between 9" and 11" wide. I'm no tire expert but if it's specified then it should be okay, right?

Scammy I am running 18x9 rear with 275 NT01 with no issues and no rubbing. For a combination wheel street and track, the 9" has some advantages. Lighter and better fit on a 255/265 tire. If it is for track only and you are running 275's get the 10.
 
This is good info for anyone really, whats the best size for street setup and then whats the best size setup for track.
So thanks for the replies and R13 i was thinking the same i thought the 17/18 setup looked the best, but for track work the (17/17) dont look that bad at all jwmelvins car looks great on stock height but they dont do a 10 in the 17 do they do it in a 18, best i check that link

OK after checking those sizes on the chart obviously the fronts are ok but what would be the best rears for NT01's? there is no 10" on the chart
Front; Enkei Kojin Wheel - 17x8 / 5x114.3 / Offset +40 or even this size, Enkei Kojin Wheel - 17x8 / 5x114.3 / Offset +35
Rears; Enkei Kojin Wheel - 17x9 / 5x114.3 / Offset + 35 which is shown above or with this offset +45
to go to a 9.5 rear you have to go 18, Enkei Kojin Wheel - 18x9.5 / 5x114.3 / Offset +30 or +15 offset
