How Do You Determine Correct Rake?

The fender method can be used in a pinch under 2 conditions
- you first check and calibrate it to measuring from the floor to the frame rail ie. check and see if there is any difference in the fender lip method first
- you are measuring from a perfectly flat surface (perferably a set up platform). If measuring when no platform is available you should slip a thin metal plate under the tire (this removes surface errors).

Assuming your fender measurements are correct and accurate then you have a 1 1/2" rake which is almost double what is minimally desired. This will degrade handling and increase rear body roll

You should try to reduce it into the 1/2 - 3/4" rake. If you are not able to do that due to static clearance problems than you will have to live with it. If you experience dynamic clearance problems such as rubbing on cornering you can consider using VB&P Extreme Springs which have a better curve and higher spring rate. These will allow a lower ride height and less body roll.

An alternative would be to resize the tires and or rear tires and wheels
and this is your only solution if you have static clearance problems.

I would not recommend trying to put on just a larger rear sway bar to reduce the body roll and solve clearance problems.

You may have to play with front (raising) & rear (lowering) ride heights to strike a comprimise. Always be concerned & check cross corner Wt. %.
