Wheel Directory: Enkei RPF1 17x9.0 +35

[el-92]

Finally got my wheels 😊

[Meanderchap]

I'm in the market for 17 inch RPF1s on stock power and street/canyon driving, and I'm super conflicted. I've been told I should opt for 17x8 +45 (225/45) because 245 is too much rubber for stock power, and steering feel/playfulness *might* be diminished compared to 225. However, out of all possible configurations, 17x9 +35 (245/40/17) seems to be the most popular option for the twins, as evidenced by this 34 page thread.

I'm curious as to why. I'd imagine that a lot of people opt for this configuration for the meaty tire look, or to get the flat face RPF1s (and I hear 225 is a stretch on 17x9). I figure this set-up is also ideal for track or auto crossing, but what about street driving? For those with this configuration, how many of you are pushing stock HP and just DDing? I've been reading through all the forums on 225 vs 245 and I still can't arrive at a consensus as to whether I'd really notice or care if I go with 245 over 225 for my uses.

I'm interested in steering feel, nimbleness and grip, in addition to preserving stock acceleration. I also like the somewhat meaty tire/flat RPF1 concave look, hence my indecisiveness.

Why don't you read your thread you already started on this issue.

Before pulling the trigger on such a costly purchase I'm trying to narrow in a bit further, specifically in regards to the reasonings/advantages one has for running the specific set-up on this wheel directory, given its vast popularity.

But people choose this for lots of reasons, but don't you want 18s now.. According to your other thread running?

I posted that topic on 12/26. The answers provided in that thread helped me settle on 17 inch RPF1s.

Most go people go for the 17x9 RPF1 because:

1) It has the flat/concave-ish look
2) It's the widest you can go for the STX autocross class that this car is popular in

With 17x9, steering feel will be a little heavier since there's more resistance from the extra tire. I also noticed some loss in agility/nimbleness in low-speed corners, but there's lots of grip and high-speed stability.

For DD and canyon driving at stock power levels, I would suggest 17x8 with 225/45 as a compromise; extra grip while maintaining good agility. But of course, the 17x8 model doesn't look as nice as the 17x9 Depends on your priorities.

If you don't like the look of the 17x8 RPF1, some nice looking lightweight 17x8 you could also look at are:

- WedsSport TC105N
- Kosei K8R
- OZ Ultraleggera
- OZ Leggera HLT

I do prefer the look of the RPF1 over other lightweight wheels... Based off what you and others have said I think I'll opt for the 17x8 with +35 offset (I think +35 is the way to go?). Thanks for the informative post!

245 really isn't that much tire IMHO. That is what I daily, with stock power. I would opt for the 17x9s, personally. You can adjust your rear grip level (if you prefer a more oversteer-prone chassis) with tire pressure and sway bars. Plus the 17x9s look wayyy better than the 17x8s. -Chase

18x8 +45 are very close to stock suspension as shown in the picture.

[ClintimusPrime]

+35 for sure. It's not going to affect the handling as much as you think it will. Plus those 8 +45 looks horrid.

[BlaineWasHere]

8" wide RPF1s look stupid IMO.

17x9 et35 on 245/40/17 is prime

Just checking, you guys are talking about +35 for 17x8, not 17x9 right? I still haven't made a final decision regarding 17x8 vs. 17x9 RPF1s. Despite numerous opinions I've read, I wish I could just A/B them in person to decide first-hand if the handling characteristics for 17x9 (245/40/17) are a deal-breaker vs. the 17x8 (225/45/17) for street driving. As you can tell I'm really indecisive lol.

17x8 +45 and +35 have the same face profile. You have to step up to the 17x9 in order to have the flat/concave profile.
