Found a pair locally for a good price... they can fit on 15x10's but my question is would they fit on an f-body?

I do not mind severe clearancing.. I just want to roll on a big tire and actually hook the car. With the car as light as it is, there isn't much that really pushes the rear tires to the pavement.

Man, that sure is a big *** tire.

It's pretty tight in my wheel wells with 30x9x15 Goodyears.

Madman had to cut, reroll fenders and rub hard on the inside of my wheel wells to make the 30x9x15 to fit.

I think your going to need mini tubs.

I have an honest question Magnus.

How is it that your car being very light(which in theory makes a smaller tire easier to hook) and stock internals needs a tire that big?

For example Rich(silver98Z) local guy who I'm sure you know of that is running 10.70's all day long with 1.4X sixties, uses 26" slicks?? His converter is just as big and he's making something like 430 RWHP.

Do you really have any suspension? I'm only putting this out there as food for thought because in all reality your car should not need a big *** tire, and it would suck to go hacking the hell out of it to fit them only to get working on suspension or something and then start bogging it and have to change back.

I just don't know the details of your suspension stuff which is really the basis of my questions about why you can't hook on a somewhat normal sized tire..

that's alot of tire to push, and totally unnecessary.

You would have to cut the front and rear, and they would still stick out 1-2" past
the top of the quarter panel, I would think.
Just borrow them and test fit them to see.

Tell Chris I said Hi.

BIGBOS

I can't see you needing a tire that big either....

I got a 28x12.5x15 ET street, that I will most likely have to ditch for a 28x10 full out slick if I want traction......

I plan on having somewhere around 650-700rwhp.....

XFiveLiter

Why the hell would you need such a ridiculously large tire for a light SI car? Just get a 10.5 tire.

SilverGhost, its mainly for street traction. I want to be able to punch it at speeds less than 70 and actually grip the street. For the track I want to run a 26" tall slick on a 15x10.

The street just doesn't hook as good as US 41 does.

I have V6 shocks in back with V6 springs. Front I have HAL R's with V6 springs, k-member, a-arms, drag brakes..

Cage should be going in on monday and then I will have a drag anti-roll bar installed as well.

I did dead hook a 26" QTP before, just not very consistantly.

Just note, this is not my racing tire. And yea, I'm sure my car will go through many changes.

I set aside some time tonight to work on the car so I'll probably pull my old wheels off and start clearancing the fenders.

Chances are I would have to test fit these though before I actually install them. Seems like it will take a bit of work (which is ok).. just not to the point where I am welding new sheet metal on the car.

we are using a tire of the size 29.5x13x15 and had to tub the car, but we also did a 4 link and a custom rear axle (this is on the Demon SS project)

on Brad's car(this is Demon SS just logged in as Brad) we are running a 28x12.5x15 and had to do some clearencing with that. any bigger and it will be a squeeze for sure.

Demon SS, thanks a lot for the info.

I started to clearance the car. I took out my die grinder and attached a nice cutting wheel. I cut the front of the fender so it drops straigiht down and will be doign the same for the rear. I will also be cutting the inner fender near the LCA's.

Resale value? ... I thought we bought these cars for life.

I got a 10.5W to fit, so I can't see why a 29x13.5 can't be squeezed in. Just make sure to do plenty of test fits.

Sweet. Keep us updated.

getting the die grinder out tonight for the 325/50/15's DR's so I don't have to run that spacer anymore Life? Pssshh, there is always a racer who wants a built car Lightweight adds resale right?

Chris, pleas let me know where you are cutting/grinding. Right now I'm just clearancing everything but I assume the big problem area will be the front inner part of the well.

I need a bigger hammer.

Magness, the spot you said you might cut off is where folks box the wheelwell ie. do a minitub.

mongse

iTrader: (2)

Here's what I did for my Ws...

-cut off bumpstop & flanges
-beat down along the seam weld towards the front (it'll push in about 1" to 1.5")
-trimmed front of rear urethane bumper flat
-beat in upper indent right above the wheel (this is where the latch is for the rear seats)
-got adjustable tubular control arms and offset them 1.25" towards the center of the car and moved the rear back about 1"

I think they fit OK.

[QUOTE=Magnus]SilverGhost, its mainly for street traction. I want to be able to punch it at speeds less than 70 and actually grip the street.

If your only running about 117 in the quarter on full slicks, how in the hell do you loose traction at 70 mph on the street?? I can't see that even on bone stock radials!!!!!

I am confused...and yes I have a fast street car too,,,runs mid 11's on radials...got M&H's on it now.

get a 26 X 11.5 X 16 tire, should be pleanty.

I've driven his car, it's not hooking on 28x9x15 et drags right now. Breaks them loose from a 40 roll.

Keith...

i did like mongse said. beat that front lower area in alot. it fits, but with a 7/16" spacer on the rear, YUCK. Luckily i'm not even going to try and race it till everything is done. With the cutoff wheel, i'm gonna make it look like Madman's inner area. Basically void of everything that is the inner fender. I have adjustable lca's so i positioned it perfectly center in the wheelwell, and i have room to fit a 29" tire, not counting what it expands at speeds though. I don't need that large of tire so I guess that's a moot point. but just like mongse, i had them built like the Billingsley LCA's and offset inwards since they are a rod end LCA. Check out his site in case you don't know what i'm talking about.

also, look back to this thread...

https://ls1tech.com/forums/showthrea...ghlight=madman

got some pics posted up from NRC Motorsports and how they fit a large tire in there. Madman's pic was up but maybe they were taken down. I have it saved on my laptop to view when starting this project. I talked to the guy who built my sfc's, lca's and panhard rod(local guy) and he said it looked fine to cut all that area out. Just maybe need a bit of "rebracing" if you take too much out.
