What do I need to make rpf 1 18 x 10.5 +15 work?
 

I just got those sized rims didnt want to have to do anything but later reading people have been having to do modifications. I will be on swift racing springs and bilstein struts. Im on 18 w/ 255 tires and i scrape the liner on hard turns.

To make them fit and still have a useful suspension you need aftermarket body panels. The offset is too low for the rear of the car.

Yeah, +15 on a 10.5" is way too proud of the rear fender. Even those running the very popular Voltex over-fender dont run a +15 in the 10.5" IIRC

Steer clear of that spec :cool:

Heres the layout vs what i run (note: my rears are fully worked!). This +15 would poke 1.09" further

Looks like im gonna have to swap em out for the 18 x 9.5 +15 .

The +15 is really not a great offset specifically in the rear of our cars. Must it be an RPF1? And are you opposed to running a spacer in the front? Im pretty sure they have a 18x9.5 +38 that would would pretty good but would most likely require around a 20mm spacer possibly a little less, I dont honestly remember bc I dont run RPF1s but I do know the info is posted here somewhere so please take a look or perhaps someone else in the fitment crew can chime in.

My main point was that I would recommend you pursue something with a higher offset.

Eric, Pretty sure your notes the RPF1's are correct. If you dont run the +38, up front, you would have to run the +18 RPF1 & the +38 in the rear, but then you cant rotate

And, for sure, the +15 is not, in any width, good for the EvO rear. Some guys have certainly done it, but they rub & all the troubles that go w/it :crap:

But, on the other side, if your going for the Stance fit-up, the +15 is OK.

Not sure if youre a function > fit type or the other way around

So stick with the stock fitment if i dont want any rubbing issues w/ also having springs

Not necessarily

You have to be willing to modify the rear fenders (rolling 3/4 or a full flat roll, fender pulling, bumper bolt relocation & a few other tricks may be needed)

Which size requires the least mods?

No definite answer, but generally speaking IMO

17x9 to 17x9.5 +28 to +35
18x9 to 18x9.5 +28 to +35

Tire size certainly plays a factor

You have to be willing to modify the rear fenders. No way around it!

Mod rear fender in what way? Roll and Camber, just roll?

Not sure if Ive ever shared my ride w/you. Visually it looks very tame, in regards to wheel / tire fit but this set-up below required the following rear fender work

• 3/4 rear fender roll
• A noticeable rear fender pull just above the rear bumper cover
• Bumper bolt relocation
• -1.9 degrees of camber
• Lower rear bumper cover has been pushed out 1"

W/T spec: 17x9.5 +30 running a wide federal 265/40 tire

Now, imagine running that +15 which pokes 1" further than this. There is no amount of work that could be done to fit those +15's properly

Hmm, very well. I guess i'll return these and get a smaller size.

Sending them back tomorrow. Does anyone else have any size inputs before I decide to task on a different size.
