Yes flat bottom and rear defuser too.

Its all a work in progress.

 

the boxes behind the rear wheel is to allow for air extraction from the rear wheel such that the swirl it produces does not rush forward, causing disruption of the underbody flow.

you coulda added a slight slope to that middle piece.. but overall pretty neat.

can't wait to see your underbody picts.

if i was you i'd probably cut half that rear bumper away and just have a huge venturi channel down the center of it starting from like rear axel back, and do a blown diffuser with your exhaust exits.

 

Yeah still working that as I will have diff cooler back there. You might not see it in pics but both center and lower have slope.

 

were you going to retain the Nismo rear wing, or go toward a dedicated adjustable wing?

 

For short term Nismo wing. Later this year Aero Motions wing will be installed. Cash for this build is coming in Septemeber. Doing all cheap stuff now.

Doing sphericals now

 

earlier shot as we started to cut. Give good view of JRZ's and the big ole Brembo race calipers.

 

Those make one hell of a difference. Between them and the SPL arms , most of the rear suspension Stiction is removed. To really complete it , install whiteline rear UCA or custom delrin bushings

 

Pure awesome!

 

And my new sexy puke can

 

Here is the car in its stockish form at 3150 lbs. well it had a little helper pushing some air into the motor. now it's at 2700 lbs with a lot more tire and downforce but minus the blower. Will be interesting to see if I lose much speed.

 

 

Looking very nice! Keep it up!

 

 

 

Simply amazing!

 

 

Wow...this work is crazy! Looks great!

 

 

 

Looks and sounds incredible!

Where does that Hill climb race take place in CA?
