Will work on going back through the build to post "build in-reverse". It sure has has been fun doing this for the past 18 months or so and way easier than doing the 78-308-GTS project!... especially in the last 3 months. The 124 has turned into a more likable project

Here are the basics regarding the suspension, brakes, & drive line:
Used the OEM driveline from face of manual trans all the way to the wheels. So far it handles the 2x of torque well and we have yet to "super" tune the controllers which should shave us down to 6 sec 0-60 to match the 2017 124 (2nd gear start). Mated the dual HPEVS AC-34 motor package with a billet aluminum adapter-plate, used the "off the shelf" VW aluminum billet flywheel so we did not have to reinvent (design/mill) a new one, customized the clutch - Mitsubishi spline pattern thrown into a 200mm VW size clutch disk (vs the 215mm stock), and a VW pressure plate. All gears in place per OEM. 1st gear is really to tall for any use and it hits speed/6000 RPM way too fast. But 2-5 are really functional and smooth. Checked and serviced trans & differential, new drive line kit (flex disc, u joints, trans mount, and center bearing), hubs, balljoint, steering, etc. All good and no major upgrades to OEM. New rotors, rebuilt OEM calipers and dropped on the 8x15 wheels. Re-sprung car with increased spring rate and rebalanced springs. Left the vacuum pump off the brake booster to see if we could avoid use of the electric vacuum pump. Easy to add but after testing with the programable regenerative braking... NO NEED. It would be overkill and the concept of improved braking via regen in combo with OEM equipment hit the nail on the head. The regen button allows pure foot off "motor" braking as opposed to downshifting and braking. It is kinda cool.. may have to wire brake light to that button as it gets more use than the pedal.
So many cool details yet to cover.. will keep addressing as time permits! Thanks for the feedback! Will stay on questions/discussion on this thread & website is Electricgt.com, or I can always be reached at
eric@electricgt.com. Thanks for the welcome Arik... signed up last year but neglected to track the build but always wanted to get it up to share.
project car (1980 124-2000) in 2015 in San Diego. 2nd owner, good shape, no rust, but still 35 years old! Drove it for a while then got after a full resto-mod-evconversion. Thought it worth posting & sharing some pics finally. It is nearly complete and just fine tuning details. It drives incredibly well and is a hair faster 
No more smog tests and the first 250 miles are run on pure charge from off-grid solar panels.
