a friend of mine want to put Weld star on his 2001 Z28 15*10" rear and 15*6 up front we need to know whats the back space for front and rear wheels to look the same as the car in the photo's







are those 7.5" B.S on the pictures? do we need to grind anything else besides the calipers? what about the front wheels what B.S to make the wheel straight with the fender?

7.5bs for 15x10s with grinding of calipers. and the widest you can go in the front would be 15x4 with 1.75bs i think

the 15x4 comes with 2 1/4" only but 3.5" wheel has 1 3/4" back space why cant a 6" wide wheel fit up front?

Actully the 15x4 comes in a back space of 1.875. The 15x6 only comes in a back space of 3.5 inches. On the rear a 15x8 with a 5.5 back space fits correctly as well as a 15x10 with a 7.5 back space. There will be some modifications required, but they give you the true race look without supporting the Chinese.

so does 15x6 with 3.5 B.S will fit correctly?

wheelczar

Yes it will look great, but each car is slightly different when ot comes to brakes and how much mods you have to make.

I meant 15×6 up front not for rear and the car wont see autocross or any hard turn ever its more like weekend warrior but we dont want to put 15×4 up front its not safety

to answer ur question u might have to use a 5/16 spacer to make them look even ..... plus if u use a spacer it will cut down on grinding if there is any needed

this might also help u

I've never heard of anyone putting a 6" wide Prostar on the front. I'm interested.

My 3.5" wide Draglites have a 1.75" backspace and they fit great, so I would think that you would want a 4.25" backspace on the 6" front wheels (if possible).

Wouldn't that make it stick out 2.5" further than the 3.5 you have?

F-Body Lover

for those who has skinnies up front is it safe on corners or some hard turns?

That's an opinion, I know plenty of people who have 3.5's on their street cars. I personally have 4's on the front of my car. I drove it daily for several months w/o an issue, and wouldn't hesitate to do so again. I had to use a 1/2" billet spacer and do some masaging to the calipers on my car. I hear the 3.5's can get away with a smaller spacer and less grinding. I installed ARP wheel studs at the same time.

15x5s would look better and still handle good.

No, not really. They're designed for the dragstrip where you just need to slowly turn into the staging lanes and onto the return road. You also get a long time to brake. The street is a whole different situation.

i have 15x3.5 up front without grinding or spacer. it doesnt come close to hitting anything.

F-Body Lover

These are 8" wide rear, 3.5" wide front.



I sold them though.

Now I've got these



15"x10" 7.5"bs

Going with these tires


325/50/15

I haven't decided on fronts yet. I'll probably go 15"x4" unless I see some pictures of 15"x5"s on an 98-02 f body that make me change my mind.

These will be my primary wheels. It is mostly a street car, occasional strip.

Pay no attention to the bumper. I backed one of my cars into another of my cars! DAMN IT!
