Tire Clearance question

I have a 67 Camaro with 2" drop spindles installed on it and I want to use 15" rally wheels with P235/70R15 1025 Firestone tires. The front end is not alined yet and the tires are rubbing the finder wells when turning the steering wheel from side to side. I don't know if they will clear after alinement or should I replace the spindles with stock spindles. Does anyone know if these tires and rims will clear or should I go back to stock spindles?

Re: Tire Clearance question

WELCOME to the TEAM! I took the GM rally 15 x 7 rims with BFG TA 225/70 x 15 off my '56 Chevy Coupe to see how they would fit my '68 Camaro with stock spindles and 1-1/2" CCP lowered coils. They fit the car standing still pointed straight. NO WAY on the street or backing out my driveway. Tires hit the front fenders. The TT "D"s with BFG 225/60 x 15's all the way around are a perfect fit on my '68 Camaro which has Hotchkis multi leaf rear 1" lowered springs. See USER CP for pix.

Those tires sound a little tall for the front. I think you'd be better off with a 60's series tire and losing the drop spindles. If you want to keep the stance lower, you might want to look into a set of lowering springs in place of the drop spindles.

Re: Tire Clearance question

Drop spindles and "most" 15" wheel don't play well together

Thanks Dave Pozzi
http://www.pozziracing.com/first_gen...geome.htm#Drop Spindles


DROP SPINDLES
Plan "D"
The drop spindle kits use second gen parts, on a cast iron spindle similar to a second gen spindle with caliper mount cast in. The steering arm is two inches lower than a stock Camaro and the caliper mounts two inches higher in relation to the upper A frame, which can cause caliper to A frame clearance problems.

Several problems develop when you use drop spindles.

You can't fit some wide tires, the tie rod end winds up two inches lower in relation to the wheel so forget wide front rims.

Geometry stays stock which is not good on a Camaro.

Just trimming the springs to lower the car will put the geometry in a slightly better position as far as camber gain.

You may have clearance problems with the upper ball joint to caliper.

You can't use any aftermarket disc upgrades, they won't fit.

Steering arms are cast in, so you can't bend them to fix bumpsteer. You would have to use a rod end and spacers on a stud.



I have to apologize for using this photo. I took it from a web page of someone I exchanged E-Mails a fiew years ago. I can't find the E-Mail or web page or I would just provide a link to his page. I think this is the only image on my page that I don't have the owners permission to use. I feel the photo shows the problem so well, that I'll leave it here for a while.

I have a matching photo with the same wheel and tire but on a stock spindle, the tie rod end is two inches higher with that combination.

Another point, this is a Stainless Steel Brakes drop spindle, I don't know if other drop spindles are better or worse than this one. I don't know if Superior spindles makes all the drop spindles or if they are all making their own. If your 17" wheels have 4.25" backspace or less, they should clear, with "drop" spindles, according to posts on Team Camaro forum.

Re: Tire Clearance question

Like Terry stated, I run 15x7 TT-D's with 225/60's up front and Hotchkis springs. They fit just fine and no rubbing.

Re: Tire Clearance question

The drop spindle can still work... may just need to try a 16" wheel ? Thats how a buddy got around it.
