I was curious about the holes made on the back bumper: Is it really effective for street race, or do u benefit only on drag? What is exactly the purpose of them holes.

do you really wonder?????????



That Home depot lip is NHRA illegal as it will signal the prestage/stage beams before car is fully set. 22x8x13 slicks will cure this.

Simple? yes,
FAST? Oh SHEOIT!!!!!!!!!

Simple and fast SOHC????????

Underbody trays and reaf diffusers accomplish this on race cars. If you can get hold of a rear diffuser or can make one, they work well at high speeds (over 160)

My hatch almost floated at thease speeds with the standard suspension and no diffuser, but then i lowered it and made a stainless steel tray for the bumper and now it sticks to the road all the way to 200, which is my max level road speed.
