now as far as slicks go what will be a good size slick m y thoughts were 26×8.5 ×15 would that be 2 wide?i have weld drag wheels 15 by 8 with 5" back space ,i jus wanna make sure i dont rub these ?'s r more for 7 owners with or close 2 my setup and 2 anyone that truly nows or has experienced a setup like mine remember stock length 8.8 rear , thanks in advance for any help

Here's a good place to get all the knowledge you would want with a 8.8 swap.

http://grannysspeedshop.com/ is pretty much the authority on LRA swaps/convertions for all generations so you might find something there about the width.

As well according to GSS the biggest tire you could possibly fit without atleast a mini-tub would be a 275/60/15 on 15x8 wheels with a 5.5" backspace. This is just how snug that fits:




edit: doh. bad83 beat me to it

Hey, I have an 8.8 on the back of my 79. I made my own 4 link suspension with a bunch of pipe and some weld in heims and then made a panhard bar and the neccessary attachments. As far as tires i am running a 10.5 inch wide tire in the back and man it is a squeeze. I don't think i would recomend running more than a 10. I have 300lb springs and when the car drives again I am hoping not to have to much travel because there is maybe an 1/8 inch clearence on either side of the tire.

hey abtosway i appreciate ur info ,can u show some pics of the 8.8 and is that with stock length 8.8 or narrowed thanks again

You were asking if a 26 inch diameter tire by 8.5 inches wide would be too wide. Bad83 stated that he is running 275/60/15 tires which are much bigger than what you have asked about. 27.99 diameter by 10.8 wide.

yea, what is your email? I can send them to you that way because I don't know how to get them online! haha

I got a raw shortened rear end from grannysspeedshop because he was selling it in his clearance section dirt cheap. Through the use of 2 inch wheel spacers, I have effectively brought the rear end back to stock length.

The springs I have used lower the car two inches and as such the control arm lengths have been adjusted slightly (still playing with them..it will be tough to tell until the car drives). Also, my panhard bar mount goes exactly where the exhaust goes over the axel in these grannyspeed shop photos, so I have run a dual 2.5 inch side exhaust.

Like I said, I still havn't got the car driving but right now with the 10.5 inch tires everything looks like it will clear and work, but no real world testing yet! we will see
