I want to share a way for P3D+ owners to increase the car's efficiency. We all know that the stock 18" wheel cannot clear the rear caliper without grinding the caliper. So my solution is to use the aero wheel up front and try to find a light 18" wheel in the rear that won't clash with the front. I've found most of the Konig flow form wheel will clear the rear caliper so I decided on the Ultraform 18x8.5 +35. This result in a 50 wh/mi improvement! Before: 20x9 +35 offset with Pilot Sports 4S (stock 20" tire inflated to 42 psi) Averages 285 ~ 290 wh/mi on my mostly highway commute at 60 ~ 65 mph After: Front: Stock aero wheels with 5mm spacer to match +35 offset in the rear. Stock tire at 45 psi Rear: Konig Ultraform 18x8.5 +35 with stock tire at 45 psi. Wheel weights around 19lb. Same commute route averages 235 ~ 240 wh/mi I'll update once I get more miles on this setup.
