The Weld Pro-Start/Draglite "problem" can not be cured with a different backspace. The caliper fin hits the "knuckle" where the hub disc rolls over to become the rim. That area is exactly the same, no matter what backspace you make the wheel. I had to grind quite a bit off the calipers on my 94, and the contact point was always on the knuckle, not on the rim. You could conceivably eliminate grinding with a spacer, but I don't like spacers in the back.

The Bogart is "made" for the 4th Gen to the extent that they weld a small spacer directly to the back of the wheel. That eliminates the potential problems of using a loose spacer.

I'd be interested in seeing a pic of where the wheel/tire sits with 15x10 Welds and a 5.5" BS. I've got the 7.5" BACKSPACE , and the tires are pretty close to being outside the wheel wells.

10" rims with 5.5" BS look terrible, IMHO. Kind of ricey, they stick out too far. I have 9" rims with 6.5" BS and they look right to me.

I just got my set of Centerline Convo Pro's from jegs. Im running 15x 6's on the front with 3.5'' back spacing and 15x8.5's on the rear with 5'' back spacing. These wheels went on with no problems at all. I didnt even have to do any grinding on the callipers. I will have pics up soon!

Also look at the Centerline Warriors. 15x10 w/6.5" backspacing and very little fin grinding. These will let you run the 26x11.5x15 ET Streets with no problem.

Let's get some pictures up so folks know what they are talking about.

Here is my car, last year...

98 Formula
15x10 Pro Stars in back, NO SPACERS, 28x10.5x15 Hoosiers
15x3.5 in front, with 5/16 spacers and ET Fronts

I would never run a 15x10 6.5 backspace wheel on my car.

Here are the 15x10 w/6.5 BS Warriors on a friend's car. They are the same as mine. I don't have any pics of mine yet. His car is what helped me make the decision...

I am running a 15X10 Weld Pro Star XP with 5.5 BS.
You guys make it sound like the tire sticks out 3 or 4 inches.
I have 275 50 15 Nitto drags, the whole thing sticks out about as much as a 17X11 Grand Sport rim and tire would, about an inch past the body. Now I like the way it looks, I think the cars look slab sided enough and a little tire stickin out makes it look mean.
Of course this is just my opinion.

I happen to think a 7.5" backspacking tucks in soooooo much beter. Personally, I think it's a cleaner more agressive look.

You get a little sidewall bulge sticking out with the wide meats, but the top of the tire and the rim are well inside the body line. If you prefer more of the tire hanging outside the body line, then 6.5 or 5.5 backspacing may work fine for you.

I agree. Looks very nice!

There are two problems with tire'n rim combos that protrude from the wheelwells...

1) If the body come down hard it can cut the tire up.

2) There ain't no way a 15x10/5.5 setup looks tough unless you are trapped in the 70's.

I don't think anyone suggested that the 15x10 5.5" BS would stick out "3 to 4 inches".... In fact, I asked if anyone had a pic so I could see what it looks like.

Don't some classes require that the tire tread be fully within the fender line, when you look straight down from above?

I also have the 17x11 GS wheels for my street tires - 315/35 DR's - and they sit just about the same place as the 7.5" BS Welds. Compare this photo to the one for the Weld/ET Drags in my post above..... almost identical.

It,s not 1973?

I have done several things to my car that others have not approved of, so what It,s my car.

As for the tires hitting the wheelwells, have not had a problem yet.
I am putting on a Drag Launch kit from Eibach so we will see if I have any clearance issues.
I think on a back halved car that the wheels jammed up in the wheelwells looks great but on a non tubbed car you need a little meat stickin out.

Ok first off, I am not trying to be a jerk. Sorry if I come off that way.
Second, we are talkin an inch here. 6.5 vs 5.5.
In my opinion those 17X11,s do stick out, but it looks damn cool doin it.
If I was goin for a certain race class and needed to be legal that would be different. I just go to the dragstrip for fun.
In my neighborhood there is a guy with a supercharged 3rd gen and his tires stick out. I will break out my digicam and take some pics, I have to upload em somewhere so it might be a day or two but then you guys can have a wild roast revtime for his wheels stickin out party.

Just a matter of taste, but I prefer the "tucked in" look. Heck, I prefer the stealth approach to the whole car. If I could get a set of stock 5-star style rims in a 15" diameter with the right width, I'd use those just for that reason.

Ok then, I'll suggest it

TonyJ's 6.5 spacing looked dead even with the bodyline. If he were running 5.5 backspacing and wider tire, like the Hoosier QTP 14.5 or the MT ET street 13.5 then, yep we'd be lookn at sticking out about 3 inches. Just depends on tire choice, as to how far it's sticking out.

Not that that's neccessarily bad... to each is own.
