Track Aero mods finished and off to Tune
Here are the new mods painted up and installed. The VRT custom built front splitter and underbody diffuser made of aluminum (thick for the inevitable OTE), and the painted APR wing. Going to Buttonwillow this weekend to tune it for the track and tire combinations we will run. (Nitto NT-01 for Modified class and Yoko Advan Sports for the Street class). Both come in 315/18 for the rears, which is nifty to get the power down.

Not going to Laguna this weekend. Just to Buttonwillow to test and adjust the aero settings, then Redline Time Attack there at the end of the month.
I also have to get the down pipes for the exhaust because I cannot make sound at Laguna Seca now. Mike A is fabricating up a pair for me right now.
Hmmm,, now i see why Mr Alvarez (VRT) never showed up for a scheduled meeting at my shop a few weeks ago about making a G35 splitter setup for him. It was for your car as it turns out from these pics. 
Those gussets look extremely hardcore Ed. Even dangerous. As an fyi, anything that goes in front of the car like that should be safe enough to drive over without causing tire damage. You also have way too much leading edge and in the wrong areas at that. In the future, i am happy to help when people can actually show up for a meeting when they say that they will.
The gussets will also cause you much unwanted turbulence up front. But again, i would be more concerned about digging the front end into the ground or it coming off entirely and ripping up the tires and underside. It looks like a giant Ginsu knife.
It is very unfortunate to see a company making a part that they do not fully understand its functionality.
The splitter should be designed to disengage from the car on its own without taking anything else with it.
Just showing some honesty here.
See you at the track.

It will work to a degree Ed, it's just not aerodynamically sound with the gussets.
There is a reason why bonded honeycomb core splitters work. And they aren't dangerous to the underside of the car. And they weigh half as much as alluminum. That splitter on your car weighs at least 12 lb's compared to our 6 lb. splitters. And we do dry carbon, silver carbon or regular glass. Don't get me wrong, we have torn off splitters as you might know, but they do not create a potential danger to your car or other cars on the track. Also, any leading edge over 4" is useless on a splitter. Def some great looking welding though.

Optimal splitter lengths on large frontal area enclosed wheel cars can be as much as 150mm (such as NASCAR vehicles), though the resulting loss of effectiveness on rear downforces typically suggests backing off to leading edge depths of about 100mm for them. That is still pretty deep, and we are less than that. Without question I am in the zone of a little knowledge is a dangerous thing, so now that I know you are involved in this, I will come knocking if this gets goofy on us. So far the only reading I have done is Competition Car Aerodynamics by McBeath and Race Car Aerodynamics by Katz.....and those really are for beginners. But the fun of this is the learning process, and I am all ears. Give me a PM with your number and we can talk. The purpose of these threads is to explore, to learn, and to share what we learn with others so that the content is helpful to the community.
See you out there soon!

Maybe we will have a chance to talk at B.W. in a few weeks. Ed,

if you put a washer in the tow hook yo can torque it perfectly perpendicular to the ground and looks better. also you can powder coat it red or black and looks better also. here's a few pics.

Right now my experience is limited to PIR up here in Portland but I am definitely looking to gain experience at other events. It might be next year before I venture out of Oregon though...
And i think i forgot to mention that one of our splitters was being run on Mike Bonanni's Z at Cal Spdwy last Feb when he won the Redline Time Attack Street Class. And VRT placed 2nd behind Mike. I tuned the wing and the splitter that weekend.
