So I should be looking for an 18X8.5 size and not 18x8? Sorry I don't fully understand what each of the numbers mean and how they correlate to each other. I have 17's on there right now and I'm just trying to upgrade them to 18's and not exactly sure what numbers I should be looking for with the larger wheel.

Evo 9 stock wheel size is 17x8jj et38 with tire 235/45/17.

So 18x8 et40 is not recommended because the offset 40mm (et40) is too much, you should be looking at et30-35, maximum et38. That Enkei is also heavy type, designed for SUV.

As for the width, 8jj is ok coz stock size is also 8jj. Evos can fit from 8- 9.5jj, some up to 10jj with modification. Easy fitment would be 18x8-9jj with et30-35.

Tire size for 18, easy fitment would be 235/40/18 as it would maintain the same rolling diameter like stock.

Hope this helps.

Ok thanks, that makes it a little bit more clear. I was thinking the 40mm offset would fit better since its closer to the OEM 38mm, but I should be looking for a smaller offset. I understand its all about spacing but not how each numbers affect the others lol. Thanks again.

6UE5T

Offset determine how much inward/outward the wheels and tires in relation the other parts of the car. If too much offset meaning too inward, then risk of the spokes hitting the front calipers and inside tires hit the suspension parts. If too little offset/outward then will risk the tires scrubbing the fenders.

Note also on the spoke designs, some wheels eventhough already seem to have good offsets but still cannot clear the front calipers because the spoke design is too flat or too much inside.

So I'm looking at the Enkei TD5. They come in sizes 18x8 35MM offset and 18X8.5 38MM offset. What would be the difference between the two? Would I go with the 38mm since that matches the OEM offset? Or would I go with the 35mm since it's a larger wheel? Are there pros or cons to either one?

6UE5T

Regarding the wheels, the bigger 8.5jj et38 will be both 6mm more inward and outward compared to stock simply due to the 0.5jj extra width. However the tires though will be exactly same position and clearances like stock (assuming you use 235/40/18).

The 8jj et35 will be 3mm outward only due to 3mm less offset. This applies to both wheels and tires position.

So in summary, the 8.5jj et38 will look slightly fatter cuz wider wheels but still inward orientation same inside the fenders. The 8jj et35 will look a bit more outward where the tires get closer to the fenders.

Hey guys I kinda looked around but the site keeps crashing on my phone but, I have an 8 prob gonna pick up some 57drs for and I'm unsure what size will fit properly with no rub, I'm not trying to run spacers or adapters. Any input would be appreciated, thanks!

We have a few 57DR posts. Heres one for you to check out:https://www.evolutionm.net/forums/ev...o9-anyone.html

In that post they were running the 18x9.5+22 which is very aggressive & will require some serious rear fender work. If you want something that will fit w/out too much rear fender work look at: 18x9 +35 / 17x9+35

If you have other questions, let me know

I recently ordered a brand new set of Rays Gram Lights 57DR's in 18x9.5 +22 for my 2004 Evo 8 MR from Japan. Anybody has any tips/tricks with regards to fitment of these wheels? I've read up on them a little but there's not a lot of info out there with regards to fitment on an Evo 8 (there is some ofcourse).

I don't mind having to roll the fenders, but I prefer not to pull them. I'm thinking about doing a 255/35/18 tire or a little less aggressive and go with a 245 if that makes a difference in having to pull fenders or not.

Thanks in advance!

Will surely rub at the rear if got passenger or go thru a dip even with fender lips rolled. Previously I used 18x9 et21 with Potenza 255/35/18 and that's what happened. I think using 245/40/18 might also still rub especially if you use more square/broad tread tires like those extreme category ones (AD08R, R1R, RS4, RT615 etc2.). For clear fitment with 9.5jj and 255 tires, you better stay around et30-35. Otherwise you may need much more negative camber like over -2°. (Mine was around -1.5 to -1.7).

Yes, the 9.5" width coupled w/the +22 will surely require the full rear fender treatment (roll, pull, bumper bolt relocation). But there are many who have installed that wheel & have chosen not to fully clear the rear fenders, meaning that there will be rear rub on certain suspension movements.
My advice is for full clearance w/no rub potential.

The fronts will be OK w/some liner rub at lock positions as long as youre not adding a front spacer. (assuming those Rays will fit w/out a front spacer?)
The +22 is a very sought after offset as it gives that right amount of poke that is desired

Heres your idea vs what i run. Even w/the 245/35 tyre your overlay is very close to what i run (FYI. My rears needed all the rear fender tricks)

Let me know if you have other questions

@everkain

Only way to know is if someone else has used that wheel or you do a test fit. I searched our forum & could not any info regarding caliper clearance on either the DR's or the CS's.

There is no simple math or other technique that I know of. Its all in the spoke & hub design that dictates caliper clearance

Is there any way of doing a test fit?

The wheel size you noted as 18x9.5 +35 is certainly a good offset for the EvO rear. The 9.5" width is aggressive & will make whatever tire size you run look as wide as possible. A nice 265/35 would be great!

Sorry cant help w/the front spacer question
Any other questions, feel free to ask

hey all came across a set of 18x10 +35 ZE40's that i wanted to use for autox. prob 265/35 A052.

im currently on Titan 7 R-10 18x9 +28 255/35. front and rears are rolled, and the rear has slight pull. I do have spacers on now but its just for looks, they run fine without them.

my question is what size spacer do i need for front and rear? and would i need longer studs? i dont want to find out the hard way lol. sorry noob to wider than normal wheels lol.

thank you for your time.

@kawshon

Many AX guys are running the super wide wheel (over 9.5"). It can be done & has been done many times. But the offset mostly used is approx +38 & certainly no rear spacers are used or needed. The fronts certainly can run a spacer but only if needed to clear the caliper.

And yes, the full rear fender treatment is needed. (roll, pull, bumper bolt & at times the lower trailing arm must be changed to avoid tire contact (reference SSB arms)

Heres a thread you should review in detail. It contains posts / tips from our most experienced AX guys on fitting the wide rubber / wheels
https://www.evolutionm.net/forums/mo...ody-evo-3.html

Regarding your question on studs. Any spacer 5mm or larger will require the longer stud. Regarding spacer requirement: There is no simple math or other technique that I know of to determine if a wheel will fit over the caliper. Its all in the spoke & hub design that dictates caliper clearance

If you have other questions, feel free to ask

I am looking at purchasing a set of Rota Grid in 18 x 9.5, ET 38
I already have tyres Pzero tyres in 255/35/18.

Currently have Enkei RC T4 in 18 x 9J, ET35.

Will there be any issues in changing to the Rota Grid with the width being wider ? Rear fenders are rolled already but not sure about the space and clearance on the inside to the shock.
