Wheels for 66-67 with C5 brakes.

Hi All,

I have been searching the archives for hours and haven't really come up with what to do for my 1966. I am looking for what people are running for 17-18" wheels with their 66-67 body style and C5 brakes (non-hybrid). I would love to know what wheels, tire and wheel sizes, back-spacing etc, for front and back on your 64-67. I really wish these cars had bigger wheel wells, I guess you have to work with what you have though.

Thanks in advance!

Re: Wheels for 66-67 with C5 brakes.

Tough one to research. I do think that Tom Farrington and Deb are running that setup on their wagon. You can talk to Tobin at Kore3 and he might be able to point you in the right direction as well.

Welcome to Team Chevelle!

I'm moving this to Wheels and Tires - maybe you'll get more action there.

On my '66 convertible back in 2006/2007, I ran Vintage Wheels Works V40's … 17X9.5 with Nitto 275/40/17 555r "drag radials" all around...

Front had the C5 brakes (from Tobin at Kore3). Tobin used my "drum hubs" and turned them down and installed new studs (not sure how the dimensions differ from the billet hubs). I ran 6.0" of Backspacing in the front and I also ran a thin (1/8"?) spacer, because the weld bead where the barrel and center of the wheel attach just rubbed the caliper (and not even all around)... While there was evidence of the tires rubbing the swaybar (paint was "polished" off), driveability was fine...

On the rear, I ran 5.5" BS with a stock '66 12-bolt and stock drum brakes... 6.0" BS worked in the rear, but IMO, the wheels/tires where too far inside the wheel lip...

stock, uncut/un-rolled wheel lips...

Here it is with Hotchkis 1" dropped front springs. Car had an aluminum-headed Big Block...

Re: Wheels for 66-67 with C5 brakes.

appreciate the V40 details (I do love 5 spokes) and thanks to the Mod for moving it to the correct forum. Eager for others to chime in.

Thanks!

Re: Wheels for 66-67 with C5 brakes.

Tony is right on with the wheel sizes and back space. Without mods front max is about a 9.5" wide wheel with a 6" BS. Rear max is 10" with a 5.5" BS. 275's are possible on all 4's. Caliper clearance will be dictated by the wheel, although I don't recall C5 calipers having issues.

Now. Disclaimer. Each car can be a little different, blah blah. LOL.

66 Malibu. STILL... Working toward participation in Optima events! Rebuild in progress.

Re: Wheels for 66-67 with C5 brakes.

Lots of popular wheels will have clearance issues with C5 calipers. Torq Thrust II's are especially a problem.

Re: Wheels for 66-67 with C5 brakes.

Yea, that's why I am trying to do my research before hand. Of course a lot of the sizes I am slowly coming up in the archives aren't available anymore

Appreciate the info all!

Re: Wheels for 66-67 with C5 brakes.

Though mines a 68; I did 4 corner C5 conversion using take off C5 parts (not kit or aftermarket). I run the MB Old School wheels in 17x8 with 4.5” backspace up front and 17x9.5 rear with 5.5” backspace. I have to run a 1/4” wheel spacer at all 4 corners to get the back of the spokes to clear the face of the caliper; I even smoothed off the “Corvette” script. I could have used even less spacer but barely and the tears didn’t touch but they were super close so I figured I’d run them all 4 corners. I used stacked washers originally to determine how much spacing was needed.
Another note with these wheels in 17”; you can’t run stick on wheel weights close to the spokes inside the wheel, they will hit the caliper.
And keep in mind exhaust clearance. I have pypes full 3” and it is super close at full compression in the rear.

No car yet; currently looking for 66-69 project/driver.

5.5" backspace is what you want, on a 15x10" rear wheel. With a 17" or larger wheel, I would go with a 5.75" backspacing (+6 offset), on a 10" width rear.
C5/C6 calipers have a lot of rotor overhang and can create issues on the front of these cars, depending on the wheel you choose.

Re: Wheels for 66-67 with C5 brakes.

I have a 66 with C6 brakes front, and F body rear. The front are the Kore3 calipers with the logo removed. The 17" wheels I used were American Racing 200S. 8.5" w/ 4 3/4" BS front, 9.5" w/ 5 1/2" BS rear. No spacers. I am now using a 18" Vision American of the shelf wheel. Lots of clearance.

The slightly smaller LS1 brakes will clear any 17" wheel.

If you haven't fully committed to the C5's.
