I have a set of 17x9 +54 CE28's. I know the fronts will rub but will i be ok with the rear if i run -3 camber and a 255 tire? Im lowered on Swift Spec R's and my fenders are stock. Im ok with running a 245 in the rear if it will work better. Just street driving, no track. I've been reading mixed things that people can get away with no rolling but i've also read that they needed a roll.

Thanks!

You probably won't need a roll in the rear but you'll likely need to relocate the tab.

I was running 18x9.5 +53 with -2.9 camber and that's what I had to do.

Honestly, you are gonna be best with a fender roll. then you could run 255 all around. or 245 front and possible a 275 rear if you wanna go staggered tire fitment

I think if you did -3.0 all around with a 235 slightly stretched in the front with a 245 in the rear you could probably get away with it on stock CR suspsension - you'd need to get a camber joint up front - i'd suggest the SPC or the offset bushing from GT Motoring (it will pull the top in for camber as opposed to pushing the bottom out - J's style S1/S2).

It would definitely be functional and I'd say faster around a track like streets (SOWS) versus a 225/255 setup.

Also, the CR has stiffer spring rates and dampers and almost looks like it rides slightly higher in front versus a stock AP2 - likely due to less compression from the higher rate springs (i believe spring length is retained).

You can even do a 225 on that front rim. Before anyone says it's too much stretch, i'd say that's the absolute limit to retain functionality. FWIW, the Singer Porsche has a 17x9 front rim and 17x11 rear rim. Street setup from Singer suggests a 225F/275R PS2s. For track they offer a 235/275 Sport Cup.

With 225 front tire and the GT offset control arm bushings, I think you can avoid the roll up front.

I'm guessing this is for the CR, which is why you don't want to roll the fenders, right?

Yes, i absolutely do not want to roll the fenders in my CR.

I've decided to run a 17x9 +54 in the rear and a 245 size tire. For the fronts i'll purchase a pair of 17x7.5 +50 and roll with a 215 or maybe a 225.

Would that work better?

That's exactly where I was rubbing with already rolled fenders when I was lowered more with my setup--17x9 +55 255/40/17 Z2 *.

I ended up raising the car another 1/2" instead of having the tabs relocated, but now I can make it up the driveway.

After doing a little research, extended studs then spacers could also help add clearance so that you hopefully wouldn't need any fender work. I believe some people run them to clear big break kits, some for aesthetic reasons, and some to be able to fit their wheels. If going that route, it sounds like the kind that lock in place to the studs would be the way to go as they'd be perhaps the safest option for spacers.
Sounds like more work to me than having the fenders rolled properly by the right person, but I understand where you are coming from. Also might /will need new lug nuts if doing extended lugs and spacers--not the expert, read it in a thread.

Alignment can have an impact and camber as others have mentioned certainly does. so there are tons of variables which is why someone else's 17x9+54 setup might work on their stock fenders with a 245 or even 255 tire, yet it doesn't work out for other people without a fender roll and or tab relocation.

Btw CE 28's are nice wheels so do what you gotta do to make them fit, but don't end up completely skimping on tires because of the fitment . Run something nice and grippy as that is what your car came with. The extreme performance RE-71R apparently runs narrower than most others in its category, and with fitment in your case I would think that is a good thing. The Hankook R-S3 definitely seems to run wider from my experience, so probably go 215/245 if going with that very tire unless you're willing to roll. If going 225/255 I'd recommend the RE-71R for sure, and even then it might still rub a little without a roll. Though with a 215 front, 245 rear setup of RE-71R's you have more than enough gripping power for the street, yet the tires are narrow enough that you may be able to fit them without as much likelihood of rubbing.
You probably won't know for sure until you try--should be close one way or the other.
If you do end up rubbing, don't keep driving like that without doing something about it or your fenders can/will get marred up.

Not willing to risk it. Gonna roll with the stockers.

Those Advan RSII by SOS are incredibly tempting...

EricJT7

RSII in 17x7.5+50, 17x9+63 would be a much safer fitment than 17x9+54 all around.
And the CR wheels are my favorite.

I have +62 TR C3s w/ 255s RS3s and all I had to do was bend up the top tab on the fronts as I was rubbing the tabs clean off...with a +54 though you may need to do a full relocate.

Fenders rolled. Im so relieved.
