I can't be more happy with my purchase of wheels. These things fit better than any wheel I've ever used on ANY car.

First let's go over the suspension set up. I'm running the B body spindle with Camaro 1LE rotors up front and LS1 F body brakes out back. The front brakes required NO modification to run these wheels but there was a back spacing issue to be understood. With the larger rotors and spindles, the front wheels tend to push out more toward the fender causing them to rub if your car is lowered like mine is. This being said, I opted for the 15x7 Billet Specialties Street Lite's with a 4.5" backspacing.

The rear brakes required a TON of grinding for the 15's to fit. These wheels were the most taxing to figure out since I planned on lowering the car in the rear as well. I originally had a 17x8 wheel on this car with a 4" backspacing but saw at least 2" of room towards the frame. I knew, going with a 275 60 15 tire, there would be some tire bulge as well. I guessed it to be better to have more back spacing than less. This way I could run a spacer if the tire got too close to the frame. The wheel I ordered was a 15x8 with a 4.5" backspace. Turns out this was a PERFECT fit. I had to roll the fender lip up but that was it. This wheel and tire combo doesn't rub on ANYTHING and I didn't have to use a spacer. :D

Here's the before of the rear caliper.

And here's the aftermath.

Totally digging the new look of the car with the "old school" style wheel tire combo. Enjoy.

In summation:

15x7 with 4.5 backspace 205 60 15
15x8 with 4.5 backspace 275 60 15

It looks great, Alex! I'm glad you got it all figured out & you're happy with the results.

First off that looks killer and really surprised that you have that 275 rear tire tucked so well. I didn't see it mentioned in the post so I have to ask is your car frame notched and mini tubbed? Again, looks killer!

Thank you very much. No...there is no frame or body notch done....yet. :twisted: I do plan on cutting as much as I can out of it in the future to run a 295 on a 10" wheel but for now, I like the look I have going here.

That makes me feel better,lol! I had 15x8 w/ 4" bs and with 275 drag radial was all into the fender lip . I sold those and bought a set of the summit wheels 15x8 a/ 4.5" but haven't had time to bolt them on yet. I have a similar set up with a GN 8.5 rear but have Gbody calipers and S10 rotors that clear the 15" wheels better! Would love to see a straight on side pic of your car with the new wheels!

Will that back spacing still work if I'm still running drum brakes in the rear?

That's hard to say. The disc brake set up may push the wheel more towards the body than a drum will. You may have to use a 4" backspace and use a 3/8" spacer. Don't quote me on this. I know this is hard to figure out without buying a wheel but if you have someone close to you that has the same set up you want to run maybe they will let you try a wheel on or something.

When using std drum brakes, the 4.5" bs 8" wide wheel usually is ok with up to a 255/60 street tire, but a 275/60 will usually rub the frame. If you are using a stock length rear with iron brake drums then an 8" wide wheel 4" bs should be great. Keep in mind if using the factory aluminum brake drums or a disc brake set that they are a bit thicker than the factory iron brake drum.

I really wish I could tell you an exact inch drop on the car but I really don't know. I have the stock springs up front with 3/4 coil cut off on B body spindles and some F body springs out back that have been previously trimmed but no clue how much.

On another note, I finally got the tire set up I've wanted up front. The difference between the tires was too much for me so I went with a taller side wall tire. Originally I had 205 60 15's and now they are 215 65 15's. They went from a 24.69" height to a 26". I LOVE this look SOOOOOO much more.

nice looks good. so you are on a 15x7 215/65 up front and 15x8 275/60 in the back no rubbing... can you get a photo of the tire to fender clearance in the back... also do you have any issues turning to full lock? I was hoping to run at least 225 or 235s up front...

The rear tires will rub VERY slightly when I go over a good bump at speeds or when banked in a turn on a certain angle at a certain speed. It doesn't happen everytime either, it may happen once or twice a week. When it does rub, it is touching the quarter skin inner structure. It isn't tearing up the paint, tires, or anything else since its just a small rub for a second or two.

As far as the front goes, I don't know how much more tire I could run without rubbing the fender itself in turns. My suspension is dialed in as far as alignment specs go but my drivers wheel sits further forward in the wheel well than the passenger. This causes the tire to contact the inner fender when the wheel is turned and I'm going up a small bump like my driveway. Other than that, the fronts don't rub.

215's are pretty wide if you get a chance to look at them. I wouldn't really want to go with more than them for a car this size unless you wanted to go for a pro touring feel. In that case, I would use a lower sidewall for better handling.


I'll go see about getting a pic for you, the sun is finally out. lol
