Rear Tire Rub - Lateral-g Forums

bulldog19 · #1 05-19-2011, 12:31 PM

I have a 68 Camaro not mini-tubbed. Wheels and tires were purchased from a supporting vendor here. On the back I have Rushforth Superspokes 18 x 9 w/275/40's and the fender lip is rubbing the outer edge of the tire. I have ground the edge of the fender lip to try and gain some room but still rubbing. I'm cautious of any further use of the grinder for fear of going through the weld between the outer and inner fender. What are my options here?
Rear suspension is Hotchkis TVSS.
Do i need to just go to a narrower tire? I hate to cause the stance is spot on with the 275 in the back.
Would a stiffer shock/spring help?
Can the rear be raised 1/4-1/2" easily?
I don't think i need much judging by the marks on the tire from where the fender lip has hit.
Thanks for any insight and suggestions.

Is only 1 side rubbing?

No both sides are. The driver side little more though.

Do you have rubber/ poly leaf pads? I HAD energy suspension leaf pads in the rear of my 68 camaro. My fender lips are rolled. With everything in the rear tightened properly my rear end could move around enough to rub on both sides from time to time. I went to a local truck shop that does lifts and builds leafs springs. They sold me metal spacers that were drilled in the middle with new leaf bolts. I took the bolts out of me DSE leafs and added the new spacers and bolts. I cut the bolts to length bolted everything back together and haven't had a problem since.

Thanks for the reply Jason, I will check into this. I think if i can get some more room between the tire and fender lip for when i hit a bump I'll be fine.

What its your backspacing? I might have missed it.

Jason I'll have to look it up but i'm thinking 5-1/2" or 5-3/4".
I have about 1/2"-5/8" between frame rail and inner sidewall of tire.

I know every car is different, but on my 68 with 5.5 bs on a 9" rim I only have about.25" from the inner edge of the tire to the inner wheel house. I'm sure I could get away with 5.25 bs. With the rolled fender lips I have 11.75" from my inner wheel house to the lip at 12 o'clock on the drivers side and 12" on the passenger side.

Find out what your BS is. If you are running a 5.5 or 5.75 your issues should be on the inside towards the frame. Normally a 5.25" BS on a 9" wheels is pretty close to spot on for a factory length rear on a 68 Camaro. Are you running a factory length rear?
