I put multi-leaf springs on my '67 and it raised the back end up way too much, so I had the springs de-arched. Now the stance is perfect but if you hit a bump driving down freeway it rubs the tires. What's the best way to prevent this? I really would rather not raise it up. Do they make like a coil "helper" spring for the shock or something? Any suggestions? Thanks in advance! This is the best site!

where do the tires rub? if they rub on the inside, then maybe some thin spacers might do the trick.

i agree with derrik.
where do they rub?
what size tire?
what rim width?
what backspace?

does de-arcing affect the spring rate adversely? i have never done it.

you can probably find some coilovers if you know the shock dimensions. but they might affect the height if they are real stiff ones.

What backspacing and tire/rim width are you running?

You might consider adding an "overload" leaf to the spring packs. It should keep the car from bottoming out on hwy bumps.

Hey Randy and Scott, thanks for the reply! It rubs on the outer lip of the wheelwell. Someone has replaced the quarterpanel on that side with less than perfect results. Anyway the body is coming down on the outside edge of the tire. I'm not really sure of the backspacing but would like to make the combo that's on there work. It won't take a whole lot to remedy the problem. Just looking for the quick and easy way. Any other ideas? Thanks guys.

If the quarter panel has been replaced, you're probably right about that being the culprit. Double check your spring hanger bushings and body bushings. Check that the rear end is centered up properly with a tape measure. A previous owner could have welded the spring perches a little off.

Have you rolled the fender lip? I've seen it done with a wooden ball bat on a '69 inserted between the tire and inner fender and rolling the car back and forth. It worked on the '69 but they have a much different wheel opening profile.

I used a set of old junkyard coil-overs to raise my car so I could fit the great big old-style L-60/14's on the back.. Rims were Fenton Slotted Mags, 14" x 9" w/3.5" B/S..

Please note that a modern 17" rim could go back like 1.5" more b/c it would clear the lower stock located shock mount!!!

They were right at a modern 298/53-14 tire, (a measured 11.5" section width x 26.5" tall), so were by NO stretch of the imagination 60's!!

My car was up about 1.5" to 2"s or so AND to me they stuck out just right with the chrome AND LOOKED FINE, imho...

Hmmm... that's a pretty ingenious idea with the baseball bat Randy! Might try it as a last resort, the reason being I just got it out of the paint shop and I would hate to chip the paint. Back in 1976 I had a '68 Z/28 with N/50/15's on it with some Monroe coilovers and never had a problem. Thanks again!
