Wheels are Enkei RPF1's, 18x9.5 +15 on all four corners. No mods to suspension. Stock camber. 265-40's on these wheels do not rub. Planning on getting a set of Goodrich g-Force Rivals for HPDE. The closest size they make in this tire is a 275-35.

The 275-35 will have a smaller diameter so they shouldn't be a problem in the rear. Not sure about the front. It looks like they would clear the steering knuckle but hard to say about under compression while turning.

Anyone know if these will rub? Would prefer not to roll fenders, make suspension mods etc. Spacers would be okay if necessary I guess.

Stock height or lowered? Most likely , will rub slightly up front. 265/35 up front will slightly run under full compression.

N80

No mods to suspension, stock height. Do you know if spacers will help?

There is a shop in Charlotte that will roll the fronts but I'd prefer not to spend the money or risk a crappy job.

I say get those fenders rolled now. Then you won't have to factor in the "will it rub" question when you decide to lower your car or get wider wheels and tires... because it's gonna happen.

I have a 18x9.5 +15mm RPF1 in the front on my car with Hankook RS3 265/35/18 and it is not rubbing, I'm lowered on Tein S-techs. I think its sitting at about 1.7 negative camber.

At stock height, I *think* the 275/35/18 should fit without rubbing. But hey, what do I know?

In the rear, those 275's shouldn't come close to rubbing anything.

N80

Thanks guys.

Not planning on lowering the car. It is a DD and my track car. Don't care about looks and no plans to modify suspension for track purposes.

If 265/35s are not rubbing on a lowered car I'd think the 275s would be okay on stock height.

The problem is that I'll probably be getting these tires just before my next track day and might not have time to sort out fitment issues. I guess I better try to allow enough time to get the fenders rolled or to buy spacers. Although I'm not sure that spacers would be of any benefit.

WetdreamsZZZ, his car rubbed with 265/35-18 , i ended up pulling his front fender for him while we were at the track. Put front camber arms on his car a few weeks later and never had a problem again. I highly suggest a set of camber arms, the Z really needs more front camber, your tires will also last longer.

Spacers, well if you rub on the outer fender lip what would spacers do for you? Do you want it to rub more?

This is interesting, how does more camber allow tires to last longer.

Not doubting you, just an opportunity to learn.

N80

I did not know where it would rub.

Local shop charges $60 per fender to roll them. I think I'll bite the bullet and get the tires now sooner than I had planned, drive it around town a bit and get them rolled if they rub.

N80

This is primarily an on track issue. My street tires wear just fine with oem camber.

Spend some time in the Enkei thread, there are several examples of this setup for you to follow

+1 for why you wanted spacers? that would just make your setup even more aggressive?

CptWiggles

I run 18x10 +15 on 265/40 all around. Lowered I rubbed on the tab at the top outer part of the wheel well, once I removed that screw and plastic tab I was fine. On the inside of the tire I can't even fit the tip of my finger between the tire and the knuckle, I'd
venture a guess and say I have about 2mm of clearance. So I'd be inclined to believe that you will rub on the inside, but can't be sure.

N80

As mentioned above, I did not know where any rubbing might take place, inside or outside. My 265s do not rub at all. And as CptWiggles mentioned the space between the inside edge of the tire and the steering knuckle is tight. On my car I feel like there is at least 1 cm between my 265/40's and the steering knuckle. The 275s will decrease that clearance by 5mm so I think there well be room there. If not, that is where a spacer would help but that would create more problems elsewhere.

And I'm not into mods for looks or for fun and I really don't want to go down the road of making mods to accomodate mods.

So I figure my options are this:

1. Get the 275/35s and make mods as needed. Not really what I want to do.

2. I think the BFG Rivals come in a 255. I'd be giving up some contact patch over the 265s I've been running on the track but to me that's better than spending money and time on the wider tire mods.

3. Settle for Hankook RS3s which come in a 265/35. I've heard good things about them but I've heard great things about these new BFGs. RS3s and BFG Rivals about the same price.

4. New camber arms to accomodate 275s. On the wish list but don't have the cash yet.

5. Go back to a staggered set up. I prefer square from easier rotation and better wear.

CptWiggles

I've found a few people that say 9.5x18 275/35 +15 will fit. My only concern would be the inside, if that fits then you may have to remove the plastic tab at the top of the outter edge of the wheel well, but that's nothing to worry about.

You should also consider that each tire has a different fitment profile even in the exact same spec depending on the brand and model

I would just go with the camber arms or run the 275-35's and call it a day

Forget about the inside 18x9.5 +35 with a 275/35 and does not rub, that combo has 20mm less clearance. I have run a 275/35-18 on my own car, yes it did rub on the outside without extra camber , hell a 255/40-18 slightly rubbed on my car with that offset. Then as mentioned , WetdreamsZZ car rubbed with 265/35 on 9.5 +15 RPF1's , it just rubbed a hair on track under full compression.

I would just do 275/35 all around , and get some front camber arms as you get the cash. I ran Megan front arms for almost 5 years , now they are still going strong on WetdreamsZZ car. The added camber will make your tires last a lot longer on the track.

You can look into rolling it yourself, probably can find someone to rent a fender roller from or go with the bat method as long as you are taking it slow and being careful, along with using proper heating techniques.

No need to roll the rears with this wheel and tire combo. Up front to tool is needed, just hands for a simple pull if it is needed.

N80

Don't know anything about pulling. If it is simple and fool proof I'll consider it. If it takes skill and finesse I might as well use a hammer.

This is the wrong place to ask but I can solve this problem by just by buying the RS3s instead. Any opinions about the RS3 vs the BFG Rival? (I'm at the DE2/3 level.)

I pull front by hand , just grab with both hand and pull. Very easy.

Tires, it's a crapshoot to what is actually better, both are great tires.
