Any idea as to when we'll get to see the end result?

Also, would you be able to integrate vents (seamlessly) on the rear side of the flares that would aid in evacuation of built up air from within the wheel wells?
IMO a properly designed undertray should eliminate air cavitation in the front wheel wells. :yup:

----------

The rear diffuser is something we have looked at, but we are going to wait untill we see what it does on the track. We did have one version of the rear bumper lower than it is now but it made the car look like a spaceship.
zzilla, I would like to volunteer as the chase car with camera mounts. This project is sweeeeet!:)

I built a DIY front undertray for a Miata I used to own. It incorporated a 1"-1.5" splitter as well, as the nose of the car easily allowed for the addition. I extended it rearward to the cross beam of the engine cradle, as wide as possible from wheel well to wheel well without the tires touching at full lock, and as close to the control arms but with room for them to move without interference. Driving without it and with it demonstrated it had an enormous improvement on front stability at highway speeds. Can't say I noticed an improvement in engine cooling, but one must be cognizant of not making the tray so long that it blocks airflow through the engine bay. A heat extractor hood was eventually added, and the front stability and coolant temps were again significantly improved. So much so that I had to add a rear spoiler to compensate. I used 1/8" black ABS plastic, and it held up quite well, even in parking lot dings. If I had gone more than an inch or two longer on the splitter, I would have added supports, but I think less than 2" of splitter won't require additional supports. I think the V would require 2 pieces; one behind the front air dam and a second piece in front for the splitter. I think if tabs were left on the ABS, they could slide into the existing slots for the air dam, and once secured with fasteners, provide additional front aero. Again, I wouldn't go overboard on the splitter length, or supports would have to be added.

If one built a tray behind the front air dam, either the existing factory tray would have to remain intact, or the DIY tray would have to be secured to the existing panels so that at least the current level of sealing in front of the radiator were maintained. Airflow leakage around the front of the radiator is a significant factor to consider.

One good thing about 1/8" ABS is that a heat gun on a low setting is good enough to mold it to tighter shapes without much effort. Too much heat will bow or melt it, and weaken it.

Hi All, UPDATE.......

I have been swamped but we are finally making the production hood this week. The rest of the panels are done, after the hood is finished everything gets block sanded then it is off for the motor and all the other goodies (In boxes) that have been taking up my garage space for way too long.

UPDATE...........

Rear bumper, side rocker panels, right fender are done. Glassing left fender today. Front bumper next week, then the hood.

Production panels are very light (have not weighed yet for true numbers)The Fiberglass that we have used is for aircraft so it has an amazing amount of flexibility for fiberglass. Things are moving along.

Anymore photos will not be released untill the car is finished that way you will be able to get the whole picture instead of production bits.
How's the drivetrain coming?:stirpot:

zz, Angelo says hello...

Few questions: looking to do some aero, where are you at with the rear wing? and regarding the hood, any status on carbon fiber? otherwise whats the weight on the glass one?

PM me if you want...

Did anything ever come of this or did the economy kill his dreams too? There were lots of updates then......nothing. Must be a lot of sanding.

Any New updates X2?

BTW, Anyone ever thought of taking the rear qrtr panels off of a regular CTS and grafting them onto the sides with glass and bondo? Just curious. Would maintain the lines, metal sides and possibly look pretty friggin good!
Hoping for pics

Update

The car has been put on hold due to we have been swamped with work. Clients come first.

We have sprayed the final pimer coat about 2 weeks ago .And as soon as it slows down a little we will jump back on it.
