17x9 40 offset 18.7 lbs and about $200 each. They dont make it in a 45 offset. Just wanted to make sure the 40 offset will fit, i have tein ss coil overs.
I might get it in the hyperblack. I really didnt want to buy wheels but i need to inorder to put on my 99spec brakes. I will be running the 17x9 front and back with 255/40/17 kumho mx tires.

You'll have problems in the front, unless you raise the height of the car in the front and/or roll the fenders. You'll probably have to go with 235 in the front with that offset. You might be able to do 245's in the front with rolled fenders but I think you'll have some issues at 255 +40 in the front.



That is 255's 17x9 at +43, not a lot of room for error. Fenders definitely rolled.

I run about 1.2 neg camber in the front and my ride height is not that low, somewhere between 25" from the top of the fender to the floor. So i have about 1.5" between the stock tire and the fender. The rpm2s are the best rim in the price range that i could find. Anyone have a pic of a fd with the rpm2 wheels.

How about 17x8.5 +35? Will that fit?

Looks like they have a 17x8 +45. Sounds like a no hassle front fitment, 17x9 +40 in the rear?

you could run tires 235/255 front/rear like the later editions of the rx7?

Yes, for the RPM2's, the most popular setup is 8" in the front and 9" in the rear.

Even if you aren't that low, taking turns at higher rates of speed or taking speed bumps or curbs going into driveways will cause the tire to come into contact with the fender. Unless you set your car up like a 4x4, you'll need to get the proper offset as well as tire sizes.

Here's a good example (18x8 front, 18x9 rear):

I think a 17x9 +40 would be ok if you ran a more conservative ride height -- more like 25.5" to top of fender arch. Your coilover springs are much stiffer than normal lowering springs, so this should be ok. I would run 255/40, raise the ride height back up a bit, and then give it a try. At worst, you'll have to roll your front fenders.

It should be said that normally I would agree with Mahjik that a 9" +40 is too aggressive for a front fitment, but many people run 285/30 up front 10" +50 without issue -- with rolled fenders and reasonable ride height.

I wouldn't say too many. Spank did chew through his wiring harness with those big tires up front.

+45 on a 17x9 is definitely safer if you want to run 255s. that is what i'm running with 255/40/17 MXs and H&R springs and no fender rolling. i've met a fair amount of people with 17x9 +40s that rub up front. especially when running 255s.

Thanks for all the advice, i might just order two 17x9s and two 255 tires and mount it to see how it would fit in the front. For some reason i feel that if i have to get 17inch wheels to fit my brakes, i should at least get something wider than stock. Its either the rpm2s or the gram lights 8.5 in the front and 9.5 in the back.

I decided on some 5zigen fno1r-c, in 17x9 43 offset front and back.

Hi reviving this thread I'm getting a deal for some Gramlight 57Xtreme with these size, 17x9 offset 40 and wanted to know if it will fit and how well it would look front and rear (how flush) I'm not into stance and stretched tyres, I like more the meaty look but don't like my car to look like if the wheels are too small... If they can fit and with what tyres size would be recommended without looking stretched? sorry for my bad english btw... Also I have Hipermax4 coilover (not slammed) almost stock right height ( preset ride height that came in the HKS coilovers)

17x9 +40 should work fine with front fenders rolled and maybe a bit of negative camber if you wanted to run 255/40-17s. Shouldn't be a problem with 245/40-17.


On 17x9 +40 you could run 235/40-17, 235/45-17, 245/40-17, or 255/40-17. You could stagger the tires if desired.

For reference on flushness, here's my car on 17x8.5 +40 fronts and 17x9.5 +40 rears with 255/40-17 front and 275/40-17 rear tires. So mentally move the front outer wheel lip out 1/4" and the rear outer wheel lip in 1/4"...

I ran the 17x9 +35 RPF1s from my old FC for about 3 years on my FD. Never had a problem at all. My fenders are rolled but not pulled and my tires were BFG KDW, sized 235/40F and 255/40R.
Worst case scenario, you may need some 5mm or less spacers, which are fine to run. Just don't put on 1/2 inch spacers or something crazy and you'll be cool with your stock wheel studs. I dont think you'll need spacers at all though.

Heres a pic or 3:

Car looks sweet! Your fronts look like 17x8.5 or narrower, though. 17x8.5 have convex spokes like your fronts. 17x9 have flatter spokes like your rears.


Spacers would move the tire in the wrong direction, decreasing clearance to the wheel lip and increasing clearance to suspension (which is not an issue for this width/offset).

what wheels were you running for that offset .

You are 100% right on both accounts. *puts down the weed* lol
The fronts were actually only 17x8 with the convex spokes for more clearance for bigger brakes...which I never bothered buying anyway. And the offset thing...*facepalm*

Apologies!! I'm blaming it on Christmas and eggnog and...um...yeah.
And thanks for the compliment, ZDan! Likewise on the '94 CW. That's my favorite year/color.
