CaMaRo67RS355 · 11-04-2009, 06:47 PM

ok guys so what all is involved for me to fit 325/50/15 mt's under my 02 SS i remember seeing a thread about this awhile back but i unfortunately couldnt find it. so what methods and tools have you guys used. this isnt a drag car so it has to be clean and look professional im not wanting to "cut" on the car unless i have to.

thanks

Unless you mini-tub the car you're going to have the beat the living sh*t out of the fenderwells and cut off the bump stops. - Which is what I did. My car is also lowered a fair amount vs. stock so that might play into it some.

I used a 9" at the "stock" third gen width with 10" wide and 6" back spaced wheels.

Another in progress picture.

the wheels im using are the fbody specific billet specialties 15x10 rear with 7.5 spacing, car is stock height in rear

The math will work out the same. I'm using a rear end that is roughly 1.75" narrower on each side, and you're using a wheel that is 1.5" deeper.

Get out your 15lb sledge.

Here is a pic Chris @ The Southern Outlaw Shop sent me. This tire is a 325. I have a pic of the mini tub, but I'm having problems with the file. If you have any questions, please email me, call, or pm me on here. KY-Turbo is looking to become the first place you go for quality performance parts.

I'll have other pics available soon. Go to the KY-turbo sponsor gp thread to see cage pics. Thanks guys.

As stated above. Cut the Bump Stops off. Hammer the shit out of the inner fenders and you are good. Stock width 9" and 15x10 7.5BS Pro Star's here.

whats the price of the material for the mini tub? how do they install do you just cut out the bumpstops and all the metal in that area and weld them in? are there any downfalls to losing the bumpstops?

the tires will fit without mini tub we did it on a stock length 9" takes a little clearing but its not that bad we were running a 15x10 billet speciality wheel as well

Takes lots of beating the inner fender wells, especially the front by the control arms. You'll need adjustable control arms to center the tire in the well and adjustable panhard to center the rear end. Will also need to roll the outer fender lips. I didn't touch my bumpstops. My car has stock rear springs with the "hose mod". I'm also running .125" spacers, I couldn't grind my brakes any more w/out punching through to the slide pins.

This is with a stock width 9" btw.

CaMaRo67RS355 · 11-05-2009, 10:35 AM

yeah i have stock springs that are uncut and the wheels wont require caliper grinding im curious if i could get away with leaving the bumpstops on there... how did you roll the fenders?

jmm98LS1 · 11-05-2009, 12:40 PM

I rented an eastwood fender rolling tool & heat gun from a member on here.

I am doing 15x10 BS 7.5 wheels and 275-60's, They fit easily. If your car rarely will hit the track why bother running the 325.

well since its a 6 speed and they tend to be harder to get to work with drag radials i figured that the extra contact surface would be good.... whats your opinion?? its just bolt ons heads cam nitrous & 9"

I think you should have two sets of rear rims, and one set would have a set of 28x10.5x15 ET Drag stiff sidewall slicks. Hooking a really quick stick shift car on a DR is not easy.

problem is i drive it on the street alot but only have the 1 set of wheels for now later im wanting to get some others to be street wheels then change out the drag radials for slicks. i know its hard but thats kind of the reason behind me wanting to do this i like the challenge i guess

I wouldn't go through the trouble of 325's. They look killer, but not worth the trouble IMO. I'm going back to 275's as soon as these wear down. i've rolled the fenders and the tires keep rubbing the fenders around curves cause i dont have adj. control arms or an adj. panhard bar.

Agreed.....that's what I do.

SPEED#1 · 11-05-2009, 03:29 PM

1slowM6 · 11-05-2009, 03:47 PM

So you like a stiff sidewall slick for a stick car versus a soft sidewall?
