Oh wow, so I forgot to keep the EM community in the loop in this project. I just got her running and driving on the new engine, bodywork is painted except the roof, still getting used to the new feeling of the car, so much has changed it feels way different than before.

To recap:
Spare tire well and rear crash bar deleted, trunk floor remade with coroplast…
New diffuser made which is now free standing
Lead acid battery replaced with 6.6lb LiFeMnPO4 pack from batteryspace, eliminating 8+feet of 2ga cable

Engine has aluminum flywheel and balance shaft delete and solid transmission mounts to reduce wheel hop on launch

Estimated 50lb gone, maybe more? Hopefully lower drag (hard to quantify since so much has changed and I’m still on the 225 width 16 inch track tires), perhaps an additional 10-15hp (needs tune)
