    C2 Ride Height

    1966 427......How far above the rear tire should the body be? My fender is actually about an inch below the top of my rear tire. I've seen others where you can fit about 4 fingers between the tire and the fender. what could be the problem if I sit to low?

    Dave, If you car sits one inch below the top of the tire I think it's fine. If you have a service or assembly manual there is a dimention for the suspension that's measured from the center of the top strut rod bolt to the center of the bottom strut bolt. This measurement will give a indication if suspension is at fault. Most people just look at the main leaf on the spring to see if it's flat or inverted.

      The measurement you want (the "D" height) is shown in your Assembly Manual in UPC 4, sheet B5. Measure from the centerline of the inboard and outboard camber strut rod bolts to ground, and the difference should be 3.69". That measurement indicates spring deflection, and is independent of tire size.

      Chevrolet never published any ride height dimensions from ground to the top of the wheel openings.

        If you look at the archives I had a hard time with some springs a long time ago and went through all the calculations (z, H, and everything else). What we came up with was that you should have a height from the ground to the center of the wheel of approxiamtely 26.5 inches. This is a good start point. I just measured my 65 396 and the back is 26.5 and the front is 25.5 inches. The 65 remember has small block springs 3851100 and they were changed in 66 to a strongrer spring. It does give a nice stance to the car!!!

          Keith,

          I assume you mean the center of the wheel WELL (FENDER) should be 26.5 inches. Center of the wheel should not change....

            Sorry. I did mean wheelwell. I have had two cars judged the first a 67 small block with new springs all around (Duntov) it sat at 27 at each wheelwell. Using the calculations in the assembly manual you would be at 26.5 to 27 all around (I looked and measured 25-30 topflight judged cars) most were in this range but some were lower in the front (25). My BB car is an original 19,000 mile car and you would think there could be some spring sag but I would guess that you would see that more in a car that has higher miles than in static wear of storage. Others on the board will be able to tell you the specifications of spring tension. I would bet that you would never get questioned if you can achieve 26-27 inch rear and a front the same or 1/4 to 1/2 inch lower. The driving up hill look with the front higher will not be looked upon favorable. Look at all the pictures in the books from the assebly line. They all had an even stance.

            Good Luck
