It has to help. No question, but I'm like others I don't want nasty holes in my bumper...I do like the 2 seperate carbon/kevlar setup but 150 bucks for 2 pieces is a little steep imo. Good product I am sure, but to rich for me.

I'd like to know if making a "mini" diffuser for the underside of the bumper similair to the VX models would be the same as a bumper mounted hole setup.

Prevent the air from going in the bumper to begin with. Sheet metal an air dam from the frame to the bumper..however would this "lift" the car @ speed?

I'd hate to be cruising 75-80mph on the freeway and a gust of wind blow me away...or @ 130mph loosing traction...?

I won't link to it here but we have had a special going for HT members at $115 shipped for the carbon only diffs. The Kevlar diffs are $150 though. Just wanted to clear that up.

i thought about doing this but i already have the vx diffuser so i dont really think adding holes in my bumper is going to make hardly any improvement.. what do you think.

Do you guys remove your rear bumper supports when you do this?
