So I would love any and all input. After tons of research and pricing, I'm just about ready to pull the trigger on enkei RPF1's
17x9.5 +18 in the front and +38 in the rear. I'm not too worried about tire rotation as these will be used as track wheels (75% autocross 25% road course). I will be putting on hankook RS3's 255/40/17's on there. Again research tells me no rubbing issues and perfect fitment. I'm on FA 500 coils now with a practical drop and a roll in the rear without a pull from previous owner. I obviously trying to stay away from spacers and fender pulling and this seems to be the way to go. This seems like an awesome set up to me. Any comments/concerns/advice welcome. Curious if anyone is running this set up as well.

 

Tons of guys run these wheels in the same specs with minimal issues. You'll be fine. Correct me if im wrong but as long as you arent too low, you can run 17x9.5 +18 front and rear without having to pull the rears. I even have a buddy who runs 17x10 +18f and +38r

 

What I've read you would have to pull the rears. Agan only going off of a post. My rear panel is abeam the top of the tire now with -2 degrees of camber on 235/45/17 MR wheels. Hard to say right now if that's "too low". I'd someone is running +18 in the back without a pull and no issues I will gladly buy the +18's all around

 

You can fit wider tires on a 9.5" wheel if you wanted.

 

i've been running 18x9.5 +38 front and rear with 20 mm spacers and ARP studs for over 4 years. no issues with spacers at all.

 

Baby steps! Haha. I love the RS3's and the widest they go is 255. When these are done I'll move up to R comps and do a 265-275. I'm running in ASP

 

IMHO you should get the +38s and do spacers+studs in the front. There is value in rotating tires for autox/track stuff too. The front end of an Evo is not a happy place for a tire to be when pushed hard. And when you start putting on $300-apiece Hoosiers it will be even more important.

I flip front to rear for pretty much every event and the tires wear pretty well. I think the ARP studs are pretty well proven at this point...

 

Lol, gotcha.

 

Looks like RS3's might not be available for next event. I'm looking into NT01's now and I was wondering if anyone was having rubbing issues with the 275/40-17 size on these rims? Any fender mods? Anyone have a comparison of the two?

 

The front tires will stick out pass the front fenders. They won't rub as long as you have decent spring rate for track.

 

If you just want to run 255/40/17 RS3's, why all the crazy offsets.

IMO, you would be better off picking up a set of Volk wheels 17x9+35 or 18x9+35. Then you could run a 255, or even a 265, tire with just rolling the rear fenders. No spacers required.

You can usually find used sets of Volks for $1500-2200 depending on condition.

 

Couldn't agree with you more. I don't want to run 18's because of tire cost. I would love to run some volks with perfect offset but those are very hard to come by the the rpf1's are $1,042 shipped and available right now.

 

A few years back I was adamant on not running spacers because I didn't want to deal with them. I ended up picking up a set of 17x9.5 +38 NT03 which are a great size that dont require spacers or fender rolling unless you go really aggressive with tire size.

I have since realized that spacers arent a big deal if done properly with the use of extended studs and a well made slip on spacer. I installed ARP extended wheel studs on all 4 corners and this season I am picking up some 18x10.5 +30 NT03 and I had a set of custom spacers machined from here for the front: http://www.motorsport-tech.com/

Moral of my story is that you should try and find a matching set of wheels for ease of tire rotations and you have no reason to steer clear of spacers.

 

Good point guys. Doing more and more research it looks like the 7x9.5 +18 fits with just a roll. 3 confirmations but it would really suck if it rubbed. Don't care if they aren't flush just being track wheels

 

Ok let me add one more thing then. +18 is a terrible offset for a stock bodied CT9A. It works for the front but will not tuck in well behind the rear quarter panels. Can you get it to fit? sure...but it may limit tire size and you may need to dial in more negative camber than what is considered ideal.

If you really want RPF1's then go with the higher offset and a spacer.
