I have a JB4 I took out of my 2020 Supra GR just before I sold it 2 years ago. It is pinned for an E85 sensor. All I’m asking is for buyer to pay for shipping. Tried to sell one of these before (for a 2016 VW Golf), was more effort than it was worth. I bought a 2022 C6 Camaro ZL1/1LE I track...

I have a set of PS 4S tires with about 5K on them mounted on Bremmer rims. Rims are spotless. Tires have most of their tread left. Got Both as tire/wheel pkg from Tire Rack. Put original tires/wheels back on my 2020 GR premium and sold car in November. Can provide pictures if needed. Taking up...

I am moding my 2020 GR with JB4 with ewg controller, E85 kit with flash for JB4. Friend who is an accomplished DIY mechanic/is an instructor at a local track (owns 2016 Z06/C7) recommends putting a new exhaust on it. Many on this site and others have suggested a new downpipe. In looking at...

What type of EWG does the A90 supra have, electronic or pneumatic?
