I recently purchased a set of silver RPF1 Front - 18x9.5 et15, and Rear - 18x10.5 et15
I am sitting on Eibach Prokit springs, sway bars and Bilstein B8 Dampeners

I don't really like the really stretched look
I was thinking of running,
255/40R18 in the front
285/40R18 in the rear

This will give me a bit of stretch in the rear for clearance, but nothing major.

Just curious if I will have rubbing issues or not with this setup?

It's probably been asked before, but I must have over looked it when looking though the 300+ pages.

Thank you
Duro

Got the wheels mounted 255/40R18 on the front and 275/40R18 on the rear
Just finished with the alignment today, and had to run from pretty aggressive camber to get the tires not to rub
Was raining on the way home today, but will check with masking tape tomorrow for anymore rubbing

I am running
-2.1deg camber in the front with a +0.10" deg (camber bolts required)
-3.0deg camber in the rear with +0.10" deg

Hopefully the tires will last alright, they are a touring tire as I do more highway and country roads than anything else.
But they do sit perfectly for my taste and look great. Will post pictures later.

Thanks

Alright...read the 318 pages.....wow! Tires I am considering....frt...245/35/19, rear..275/35/19. My question is wheel offset. Fronts are 8.5" with 30mm offsets...rears are either 25 or 40mm options. I want no rubbing issues, but still aggressive looking. Stock 2012 Genesis Track version. Thank You!

This is 8.5f/10.0r with +20f/+25r, lowered on coils. No rubbing ever, including track days.

Before anyone gets their panties in a bunch, yes I tried using the search function but it was useless.

Anyone running a square setup with 275/40-18 with 18x9.5" +22 on all 4 corners? If so, any issues? I'll be running this on road courses, not just street.

Stock R-Spec suspension, and camber will be around -1.8 front, -2 rear.
I ran 18x9.5 +22 with 255/35/18 all the way around. The handling was….squirrelly. I dunno if I had **** tires(Dunlop Signature HP’s), or if the square setup had something to do with it. I sold that setup last week and I’m going back to a staggered setup.

Any rubbing issues in the front with that size? And are you lowered? How much camber are you running?

Thanks.

I am lowered 1.5” in front on ST Suspension coilovers. I was rubbing on the coilovers until I went to 0° camber. Then I was fine. I actually changed the wheels and tires out. I’m running 19x8.5 +35 with 5mm spacers in front and 19x10 +25 in the rear. It handles much different(better, to me) on a staggered set up.

I'll probably go 255/35 front, 275/35 rear. It's the same width ratio as OEM, just with a bigger contact patch.

Okay I plan on getting ESR SR07
19x9.5 +22 front with 245/35
19x10.5 +22 rear with 265/35
I’m gonna be dropping my car with BC racing coilovers and was wondering if this setup will rub without rolling or pulling my fenders. Also will take any input if you think I should change tire size etc. what do you guys think would work best. Here’s a pic of how I’m tryna get my car to sit

I just committed to buy some Rays Engineering Volk Progressiv Spoke 19" wheels. They are gunmetal with a polished lip. Front is 19x8 +43 and rear is 19x9.5 +38, tire size is 245/35/19 front and 275/30/19 rear.

Crossing my fingers that these will sit right on my GC! I got a good price so i could always re-sell if they don't fit. But i want it to work. I'll post pics if they look good.
Did these ever fit? I'm looking at a set of 19x8.5 +40 front and 19x10 +40 rear.

Is the common 19x9.5 / 19x10.5 (or 11) +22 good for cornering performance at the track on a BK2 Genesis Coupe 3.8 Track?

I've searched through countless posts and pages and it seems most are only concerned with fitment and straight-line grip, but not cornering performance. Interested in getting seat time at a local track so looking for a good compromise between looking decent while also not contributing to more understeer that this car already has as it is my daily driver.

Since most people running the above fitment are running -2+ degrees of camber in the rear to avoid rubbing, would that not induce more understeer?

I have just installed PBM or Parts Shop Max Pro coilovers on my BK2 and want to run the above sized wheels with the common 245/35 F - 275/35 R tire sizes. I was thinking of doing -2.5 camber in front and -1.0 to -1.5 in the rear to help dial out the understeer, or would that not be enough to mitigate the extra rear grip when trying to rotate the rear of the car around a corner?

Would going for a 19x9.5 +22 in front and 19x9.5 +15 in the rear be better for my use case as a good balance for performance on the track and looking decent?

What are your suggestions?

Hey guys I need some help. So I am planning on purchasing some esr wheels but I need the center bore hub rings. I do not know the size and was wondering if anyone could help me out. I am planning on ordering apex series AP6 19x9.5 +22 and 19x11 +22.
Really appreciate it.

The wheels will fit on stock suspension, but will look goofy since you're not lowered. I suggest getting coilovers/bags first instead of riding on aggressive wheels on stock height. I actually ordered from RavSpec myself. Did my research beforehand so I didn't have to ask them what fits and what doesn't. They're being on the safe side so you don't end up ordering wheels that you don't like the fitment on and end up complaining to them. I'm running 19x9.5 +12 and 19x11 +18 on BC coilovers just fine. I rubbed in the fronts since my camber wasn't negative enough so I rolled the fenders. If I had ran past -2.5 camber, I probably wouldn't have had to roll them. From what you said, you wanted the wheels and plan on getting coilovers down the road. Lots of people on the forums have ran 19x9.5 +22 and 19x10.5 +22 with 275/35 and 245/35 tires on stock height. Sits flush (maybe very little pokeage) with the fender. So if you ever planned on going lower later, it would still look nice. Guess it really depends on what kind of look you're going for. Stanced? Super aggressive/slammedenuff? Just flush? If you're wanting aggressive then get the coilovers first and then wheels. Here's a pic of the day I first put the wheels on. I have since lowered it to fill the gap but still fits nicely.
What size are your tires?
