My gut feeling is there is 'some' relationship to how far out the front edge is and how much space is 'allowed.'

Supercars can cheat,as they have active suspension,lowering the car only when it's out of harm's way.

5" over 39" is a 7.4 degree angle.

5/39 = 0.128
sin (7.4) = 0.129

And that is why i didn't lower my Camaro, and i'm not going to lower my truck

You just found out why I use ugly, expensive, hard-to-fabricate, indestructible conveyor belting for my air dam.

the cost of replacing the IMPUL front bumper is around $1800.
The IMPUL product is a Japan Domestic Market product(jdm) and has to be crated and shipped from Japan. There are probably only 10-15 full body kits installed in the USA. (i was the 4th in 2005).
I decided to repair it and live with the inperfections. Afterall, I have 255,000 miles on the car and will always keep it since the resale is nil. it still runs great and just last week got a compliment on the ride quality. (again)

Here is the current state of the body work:

Good recovery, got to be a jack of all trades in this game eh?

[mcrews]

I wish all bumpers were made out of foamed urethane. That stuff always bounces back.
