Don't get your hopes up. Judging by the design of the wheel, I'd bet they don't clear the brake calipers.

Its all in the backspacing/offset.

mchat, when I talked to Bogart they mentioned you. What exact offset did you go with and how much clearance is left between the wheel and caliper?

Either way that offset is not ideal as its better that we find a correct fitting wheel without having to modify fenders.


As I stated before, my tires rub because my suspension is so low. You can prevent this from happening (If you have coilovers) by raising the suspension a bit. It's really no big deal to roll the fenders. The metal is thin and bend very easily. The tire only sticks out about a 1/2 past the fender. I will take some snap photos later today.

The fit very well and will clear the stock strut lower perch. These are awesome and for the price they can't be beat

Like I said Steve, I'd rather list wheels that are appropriately sized meaning no modifications. You may think its "no big deal" but I sure as heck don't want to be messing with fenders when I can find a wheel that fits right.

In any case, thanks for bringing up the K1 wheels because Tirerack can also do the 15x8 K1's in a 32mm offset which is a much better offset.

K1 added. Much heavier than the others but its another alternative.

At the time when I bought my wheels, they didn't offer 32mm offset. That's great. They will fit much better. Also, just so you know, a heavier wheel works wonders on front wheel drive cars. It's bad enough that the front end lifts through power transfer and it's even worse when you lighten the unsrung weight to make matters worse. Just a thought

They have a 15X8 really? I didn't know that.

Yes. I forgot that they offer blanks of the Kosei K1 in numerous offsets. They'll drill any bolt pattern. This includes the special 15x8 size.

There is more to it than that. Our brake calipers overhang the wheel mounting surface (by about an inch), this is where we have problems finding wheels that fit.

When talking about these kind of wheels, instead of trying to figure out the offset, find out the backspacing. The backspacing will remain the same whether you are running a 7" wide wheel, an 8" wide wheel or a 10" wide wheel, whereas the "offset" for each of those will be different. IIRC, the backspacing was 5.25" I'd have to check to be sure tho.

That is not correct. Backspacing will vary from width to width and they will even vary in the same width depending on offset. The backspacing is measured from the inboard flange of the wheel to the hub mounting surface. If we take an offset of 38mm say, a 7" wheel will have a backspacing of 5.5" where as a 8" wheel will have a 6" backspacing.

IIRC, the Bogarts will run close to $400 ea for the front. For rears, the non-billet centered wheels are doable for close to $200 ea. They won't match the fronts perfectly (since the fronts will use a billet center, and the rears will not) but will be close. If you want an exact match, then the rears will need to be billet centered as well and that'll run you again close to $400 per wheel.

The nice thing is the wheels can be made in just about any wheel width you want in, IIRC, 0.25" increments.

Here's a picture of mine mounted w/ 8x26 Hoosier slicks:




So who at Bogart do we have to contact to get the same wheels you are running? And what size skinnies do you run?

No, what I mean is the backspace remains the same for our application, no matter what the width is. If you run a 7" wide wheel you'll want 5.25" backspace. If you run an 8" wide wheel you'll want 5.25" backspace. If you run a 10" wheel, you'll want 5.25" backspace. This keeps the distance between the inside of the wheel and the suspension components the same no matter the width of the wheel.

Obviously if you keep the Backspace the same, the offset changes; and if you keep the offset the same, then the backspace changes.

Rich is the guy I've talked to. Or if you want, I'm local so I can get in touch with him. The rear wheels are 3.5x15's.
