Here's how to find your Vertical Center Gravity:

You need a scale set, and to have your race car set up as if you were about to go out on the track (radiator, tire pressure, oil, fuel, helmet; all in race condition).  You also need a set of blocks six to eight inches tall.

First, weigh the race car normally, then record the total weight (T) and the total number of pounds on the front tires-nose weight (N).  Then carefully place the blocks under the rear scales (you may find it useful to lock your rear axle). Now record your new nose weight (NI).  Next, subtract your original nose weight (N) from your new, lifted nose weight (NI) and you will have the difference (Nd).

Figure it out using your calculator…

a. Multiply the nose difference (Nd) x 1660= (A)

b. Multiply the total weight (T) x 8 (the height of the blocks)=(B)

c. Divide your previous numbers, A by B, and this equals (C)

d. Add this number, C, to your axle centerline height or spindle center, and the number you obtain is your vertical center of gravity.
