Agreed!  It's looking great....can't wait to see what kind of wild bodywork you have planned for it.

Its already fixed. I have these unusual gnose wide body panels i think are fairly aero efficient. So really the only decisions are if I want to run a cowl induction hood vs. standard no vents. And tall rear 7" spoiler vs whale tail. 

 

Input is welcome. Leaning standard hood and big spoiler. Working on mounting these NOW.

It is just insane how many hours I have put into mounting the hatch. The simple things always take the longest. And I already had brackets fasteners from previous install. Had to fab up my own support strut setup. And I am still fine adjusting the entire thing so someone can remove and install quickly.

Hi everybody, long time for updates.  Been quite busy with kids and a very nasty divorce going on.   The good news is my garage and cars are still intact and I am still making progress, although very slowly.

 

Car is very close to track testing.  I decided to have a new pair of steering arms machined to match the front geometry.  I will post more when they are finished.

 

In the interim, I took the time to catch up on some side projects I wanted to do.  With the advancement of AI, some of the projects I considered impossible a couple years ago have turned out to be quite easy now and very inexpensive.  Based on Arduino technology, I have integrated a motion sensor into my data acquisition system.  I use a Race Technology DL1 Club box which is limited to 8 analog sensor inputs, but can decode an almost unlimited amount of CAN signals.  So I built a circuit that decodes the motion sensor and outputs a CAN signal.  I now have 3-axis roll, pitch, and yaw angles along with speeds and acceleration live data.  It will all be packaged in a small box that mounts in the car.  

 

Next is a infrared tire temperature monitor.  A 16x4 temperature array sensor once again combined with Arduino and CAN output board.  I am trying to package this as small as possible so it can be mounted on brackets roughly 4" above the tire. Again real time data of inner, middle, and outer tire temps while driving. Hopefully saves a lot of time when dialing in the camber and pressures. 

 

More to come...........
