narrowing rearend and 315 tire? i am getting ready to send my rearend off to get it narrowed and i am wanting to have to be able to run upto a 315 drag radial. the car has a wolfe mini tubs in it. the tires will be on 15x10 5" backspacing wheels and i am going to narrow the lower control arm bracket down to the size of a heim joint for more clearence. now for the questions
i want to be able to tuck the tire up under the car and with taking 4" off each side it looks like the tire will be tucked about 1.5" does this sound about right?
what do i need to do to get the control arms to clear the tire? cause after looking at it i dont think that just the offset lower control arms will be enough clearence
and does anyone have the measurements to the rearend like from flange to flange and the end to end of axle houseing where the bearing go in? mine were already cut off and i dont have a stock houseing to measure from
sorry for the long post just want to do it right the first time and i am all ears to any suggestions thanks for the info

The easier thing to do would be get the wheels and tires you are gonna run under the car with the rearend out and take the measurements. That will be the only way to make sure it will work before spending the money to have it narrowed and all.
I just don't see it turning out rite without doing it like this. That way you can put the wheel and tire where you are wanting it and make sure it will clear the LCA and tuck the way you want it to tuck.
Just my .02.
And you will for sure have to narrow the LCA bracket to run them.

The tires and wheels are under the car but I did not have a good rearend measurement to start with to figure out how much to narrow it. I know I will have to narrow the brackets on the rearend and from the looks of it I will have to do something with where they mount to the car also. I have the offset control arms but I believe that the tire will still hit the tire from where I want the tire to sit.

If you are narrowing it, it don't matter what the length is to start with.
All you need to do is get the wheels with the tires mounted setting under the car where you want them. Measure from the back of the wheel to the back of the other wheel and give that measurement to the shop narrowing the rearend. Measure from where the wheel mounts on the back of the wheel to the other wheel. Also put the LCA on the car side and see if they will clear with the wheel/tire setup where you want them. Should be able to tell if they will fit with the brackets narrowed this way also.
They may want to know how thick the rotors are. Should be 1/4. They already know how far the axle will stick out of the rearend on each side.

well i did some measuring and with 1" of clearence on the inside from the tub to the tire. it looks like from the back of the wheel flange to the back of the wheel flange is 57"
i may have to move the tire out a bit to get the control arm to clear the tire but i would really want to keep the tire tucked as much as i can
chevelledave are you still running the stock style shock cause i would like to keep the qa1's that i already have.

Need to get the control arms on and mock them up with the wheels setting where you want them. That will cut out any guess work on narrowing it and it not working. You don't want to end up buying another set of wheels or even trying to get the axle housing fixed.
Do it once and know that it will fit once you get it all back. Measure/Mock it up 100 times and only cut once.

i know what you are talking about doing it 100 times lol. this project started out to be a simple wheel and tire swap put has started turning into alot more so far it has been a off and on 6 month project.
how many people have took and drilled threw the frame and welded a bushing in it so you can move the contol arms more under the car? and run the bolt threw the frame with the bushing in it then hemi then threw the factory mounting point. i hope you understand what i am talking about.
i would like to see under some of the radial cars like fireball's cause i know his is setup like i want mine. and there is a purple ta that i remember see on here that was slammed on 315's.
