Interested in this diffuser, but do you have tested data for the speed rating and drag/stability/downforce claims?

thanks

Love your avatar, haha!


No CFD analysis, only testimonials from customers (professionals to amateurs) noting an improvement at high speed. We tested the full diffuser 12+ times at the Texas Mile, reaching 218 MPH and the diffuser kept the car stable and was a solid factor in helping achive the 2nd fastest time in the world that year for SouthSide Performance. The diffuser fins (which you are interested in) were tested at 175 MPH and held strong with all of the wind resistance.

Is the rear jack point on the diffuser still usable with the fins since there's a slight flex when propping the car up?
Yes you can use the jacking point with the fins attached. It might be more difficult to reach the jacking point, so you'll simply need to jack the car up on the left/right side and then that will give more clearance for the jack to reach the lifting point on the diffuser.
