Cannot speak for JPC of course, but my ex-car is 400+ lbs lighter with new build, so closer to 3200 lbs. We did it my deleting most everything on the car, that does not contribute to a 1/4 run, while maintaining sufficient structural integrity. So car is no longer streetable.
A ton of wiring & wiring-harnesses were removed. A/C, heater, audio, windshield wipers, interior panels, and such gone. Kirky racing seats saved quite a bit. Also moved stuff from nose to mid or rear section of vehicle. Like the 5 gallon fuel cell in trunk and one large transcooler located where stock fuel tank used to be, rather than behind radiator.
I can only imagine that JPC's budget allowed for some very sophisticated weight reduction...maybe lighweight brakes (expennnsssive)? Also helps some that the JPC car does not bear the weight of FI. Regardless, Justin's builds are always innovative and super impressive
