My ZO6 has been lowered on stock bolts by the previous owner. I would like to measure the Rake and make sure I have at least 1/2 inch difference from front to rear. What is the best way to accurately measure this? I have seen on other posts people measure from bottom of lower pannel behind the front tire and the same in front of rear tire but this does not seem very accurate. Any advice? Thanks. :z: :usa:

1/2" - 3/4" of rake is correct but measuring from the ground, through the centerline of the wheels to the fender lips is not the ideal method as every car is different in this regard. The fenders are bolted on which can result in less than accurate measurements. Even on the same car you can obtain different measurements from one side to the other. Instead, measure from the ground to the framerail just behind the front wheel and again just forward of the rear wheel.
:cheers:

OK, here's something that hasn't been clarified in any of the ride height threads that I've found.

Measuring from ground to top of wheel well on my car:

Front: 26 1/2"
Rear: 27 5/8"

Measuring at the frame rails directly in front of and behind the holes for the jacking pucks:

Front: 4 1/4"
Rear: 4 3/16"

Fenders show 1 1/8" rake, frame rails show 1/16" rake the wrong way! Granted my new suspension isn't dialed in, but just want to illustrate the comparison.

Edit: its important to note that my measurements are with the same size tire all around, however that only accounts for .7 inches of the 1.125 inches of difference. With 1/16" of negative rake at the frame rails (which could be due to my floor) there is still almost 1/2" of rake when measured at the fenders.

I lowered mine the maximum on the stock bolts. Here's the method that I used personally. I know that body panels vary and they did put not by much. So when I lowered it I insured that the amount that I lowered it was the same. As far as the Rake is concerned. I have a pretty good eye and my wife's eye is even better. I know this is not very scientific, I eyeballed the factory look. Lowered it, drove it for a few days eyeballed it and I'm satisfied that I still have some rake in it. :blush:

I recommend measuring at the frame points mentioned by dmtnt above, not the fendor wells. The fendors are bolted on and they aren't designed to be the same height off the ground. It is the frame you really want to use as a reference. :cheers:

Found a thread on another board by C4C5specialist and here is what the specs say about ride height measured at the frame rails:

HI there,
J trim height is measured at the shipping hole below the front fender, behind the front tire. This spec is 5.98 in or 152mm
K trim height is measured at the rear shipping hole in front of the rear tire on the frame rail. The spec is 6.18mm or 157mm.
Allthebest, c4c5
So apparently there should be approximately a 5mm difference front to back measured at the frame rails.
