What do you think is the best rim size for a 315 60 15 to drag race on.

The car has a wide enough tub to run either with ample clearance.

Well with a side wall that big I would think you would only need to use a 10in rim and anything bigger would just be adding weight.

the wider rim will give you a wider footprint and be more stable on the top end. drag radial wont be as unstable as a slick but im sure the wider rim will be more stable. makes sense to me.

Difference from a 10-12" rim is very little, I am mainly looking for what the fastest guy are running these 315 60 15's on.

I have sen cars go fast on both, but I was thinking a 15x12 will give me more options later if I run a 10.5w tire say 33x10.5w I wouldn't want to put that on a 10" rim.

chrismorales75

You run 15x12's don't you? What size back space and how much did you narrow your rear in your setup?

I have 15 x 14s on our drag radial Mustang.After the beadlocks they came out to be 13 1/4 wide. Works killer for us.

15x14 with a 315 60 15? or a 10.5w I thought a 15x12 with a 315 60 15 had a 14.25 section??

Call me stupid I am confused

Its a "drag RADIAL" car

chrismorales75

How's it end up being 13.25?

I thought a 15x10 was 13.5 section

15x12 is a 14.25 section

So how the heck does a 315 60 15 end up being 13" wide on a 14" rim?

Whose car, have a link or pics I have to see this?

The wheel ended up being 13.25 sorry.

Will Stevenson has been 7.51 @ 191 with 15x10s on his F-body. I think I remember him doing some testing with 12" rims and it did not show any improvements on his car, but did cause some clearance issues.

CutlassRacer

Cool ladder bar setup in the Mustang.

chrismorales75

I don't have clearance issues I have a full tub and 16.5" of clearance to play with

chrismorales75

That's a cool car

car_fixer

umm i dont think thats a ladder bar, looks like the top brackets are being used, i guess its a stock suspension type d/r class? still a nice lookin car, well down here atleast.

that is a "stock type" suspension. lots o controversy. it has a mini tq arm as well as LCA and UCA. hard to see the details. bitchin fast drag radial car for sure.

Wrong. See the uppers?

CutlassRacer

HA HA HA HA. That was more of an inside joke to the guys who run stock suspension. That piece was originated by Wolfe (as far as I know) and should not be legal in ANY "stock suspension" class. Since when to Mustangs come with torque arms (or a single ladder bar as they have been called)?? And dont even gimme that "well its there for safety" junk either. Its there to prevent tire shake and to keep the tires planted. To avoid controversy at Orlando this year, Wolfe did not have it on his car and went pretty freaking fast so obviously its not totally necessary.

Chris, put them on the biggest bead lock rims you can squeeze in there. That'll look cool

mine are on a 15x12 w/ 3.875" backspace. i built my rear starting with a bare housing and when finished i compared the width to the width of a stock rear and i believe it was 16" narrower so 8" per side. i have a 4-link though.
