Fronts 245's on 8.5" wheels; rear 285's on 10" wheels. Wheels are CCW's. Have run with this combo since '06.

Our friend Pablo is currently racing on 285's all around (like Mike's set-up). I may try Mike's suggestion of putting the rears up front just to see if 285's will fit without flairing, etc.

The car is dramatically different with 285's all the way around!!!

Hi Mike,

Did you have to flare the front fenders?

pmcrespo

As Richard stated, +1 for square setup. And credit to Mike Ward and Scott Good who convinced me to take the plunge! Best thing I ever did from every angle...

I run the Enkei Nt03 Wheels 18x10 which have a 60 offset and 285 Hoosier R6s. I do run a 5-7 mm spacer in the rear to prevent the tire barely rubbing the inner fender-well under heavy loading and 2.4 camber which I had been running (2.3 seems to be my sweet spot for me now).

I never had issues with the front rubbing the fender lip. On full lock, the tire does rub the wheel well cover and barely rubs the one brake line .... Nonetheless, I try to keep the full-lock drifts to a minimum! LOL

My 968 has standard non M030 brakes/spindles.
I am in process of installing Moton Clubsport coilovers/new coil springs/minimal torsion bars/M030 stabilizers.

Will there be any clearance issues with the above with either of these wheel selections ?
- 17in x 7.5/9.0 Cup2
- 18in x 8.0/10.0 MY02 (50/65 offset).

I would think you would be fine in either case

So, back in the game on this after deciding it was too complicated to create a set of custom wheels. Found a set I am very interested in. These will not be track wheels as I will save my Cup II's for that, granted I like mikew968's square set up

These should be about perfect, with the rears filling out the fenders well...right?
18x8.5" 46 offset fronts
18x10" 54 offset rears

I bet these will be just fine - just as long as there's no spacer in front. I needed a front 7mm spacer for my 18x8 et50 in order to clear dust cap. Everything fits barely with 225-40-18 tires.

I also have the 18x10 et65 (with 295-30-18 tire) setup in the rear. I still have room for a ~10mm spacer.

Still looking to put coilovers in front so I get wider wheels in front.

Good Luck!

So, I guess I will see if they fit. My expectations are they are going to be perfect. Stay tuned, and I will let you know. No space planned for the front at this time. I suspect these will have a very flush fitment to the fenders. Now, I just wonder if moving from 17's to 18's will really change my camber adjustments made last year. My expectation is with the same tire diameter, it shouldn't affect the set up?

RH 3.6's

8.5x18 - 46 front tires 235-40-18
10x18 - 54 rear tires 285-30-18

Sumitomo HTZII's (they were free)

Couple of things to consider. The difference in profile is REALLY obvious. Looks like I am driving a "Big Wheel" from my childhood as the front are noticeable larger. They clear at full lock by mere hairs... The rears look stretched. The tire's rim saver doesn't even come close to saving the tire.

So, I am wondering if I moved to a 235-35-18 in the front and a 295-30-18 in the rear if that would work well. Thoughts? I am not even sure if I can find matched tires at these sizes, as the 295 is not a common size. All I know now...it simply doesn't look right. I assume it could be the tires as well.

Thoughts from the team of experts? I will have photo's up soon.

mtnspeed

I have these size wheels on and my 285's look a little stretched in the rear. The 8.5 with a 45 offset does fit in the front, but the 235-40's look silly compared to the rear 285-30's. One looks stretched and the other one looks fat...

Assuming you have rolled fenders front and rear you can run some pretty wide rubbers. I am currently running 245/40/18 fronts and 305/30/18 rears on a 951S. Looks a little bit ridiculous but in a good way. A good/flush fitment I can recommend on stock MO30 set up would be 225/40 with 7mm spacer to clear front bearing caps with 50 ET, and 295/30 in the rears with parking brake cable zip tie to the trailing arm- no spacer needed in the rear.

mtnspeed

No rubbing or any issues, but it is tight in front. Think I am going to move down to a 224-40 vs. the 235. Rears with a 54 offset and 285-40's could actually come out a bit more if I wanted. Pretty sure 295 would fit, but don't see the need.

james6speed

mtnspeed, I also have RH's on a late offset 951, with the same offsets as your 3.6's. My car is not lowered. You need to get 225/40's on the front. The 245/40's are too tall for a 285/30 rear combo. If you move down to a 225/40 and a 295/30 rear, they will be almost identical height... now the $64k question is will a 295/30/18 fit on a 10" ET54? That is where I am at right now, as I am contemplating putting on 295's, but I am afraid I will rub under boost, even at stock height. I am undecided on if I should pull the trigger on them or just replace them with the current 265/35's although I can get the 295/30's much cheaper right now.

Thanks Mike!
