Enkei rpf1 17x9.5 +38 fitment question

[Acrdys]

Hey! Getting new wheels in for autox.

I got on the lsdmotorsport group buy and went with the 5x100 17x9.5 +38 rpf1 wheels.

Any idea how wide of a tire I can fit without any issues?

I'm on tokico d-specs + rce yellow and I have about -2.0 camber in front and about -1.7 camber in the rear.\

Also! can I fit 255/40/17 on 17x8s for now? do the pros outweigh the cons for autox?

year of car? any other mods?

[Acrdys]

2007 wrx oh I guess 27mm front sway bar and a 22mm rear if it matters.

you look like you rub in the back

[Acrdys]

I do rub in the back . I'm guessing going from 17x8 +48 to 17x9.5 +38 on the same tires will still rub?

[edit] rolling fenders this afternoon. Also got a new alignment

-3.9 up front with only camber bolts. Can't wait to take it out to the next auto-x event ^^

You will really rub, sorry to say

I'm rubbing with 255s I was hoping to fit more tire under there in the near future. Called my friends to help me roll the rears tonight. I'll post picks on update.

Pulled the fender... car should now be ready to accept the 17x9.5 +38 rpf1s

9.5 is a bit wide for the 02-07 cars.... but it has been done before... many times.

You will have to roll both front and rear fenders. The rears you might even have to stretch them a bit.

The issue isn't the fender though... it's the strut. I run a 17x9 with a 44 offset, and a 255/40 tire.... and I have about 2mm of clearance between the strut and the tire, with 2 degrees negative camber.

If you plan on running a more aggressive camber setup on the front for the track /autox... you may need to use a 5mm spacer to be able to clear the strut. But... that leaves more room for rubbing the fender too... so it's a give/take relationship.

Either way... picking up some 5mm spacers could save you a set of tires. I wouldn't go any wider than a 255 though.

Informative as always! I'll pick up 5mm spacers running -3.9 camber on my front now

Still havn't rolled the front yet... don't want to lose the wheeel well stuff ><

Can't wait for next season!

I ran neg 2 degrees of camber on the street (still do).... and when I would go to the track, I would bottom out the tophats on my coilovers to a neg 4.... thats a good angle for track setup.

If you don't have adjustable camber though.... neg 4 is a LOT of camber to run on the streets. Your car will float around quite a bit on the highway.

Contrary to popular belief.... Camber isn't what kills your tires.... it's Toe.

If you absolutely must run a neg 4 camber.... I would tell the alignment shop that they MUST be able to get the toe on your car as close to zero as possible. Even a .05 will chew your tires up in no time.

For a non-adjustable setup.... I would reach for a neg 2.2 to neg 2.5.... no more. If you are still understeering at the track..... pump up the front tires to as high as possible..... and think about a stiffer rear swaybar.... or an adjustable rear swaybar that you can adjust for the track. (Hotchkis, Cobb, etc)

Good luck.
