I hope so as well. Maybe whomever gets it would be kind enough to post a picture and their experience with it (:

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...

This is a tire rack supplied replacement for the OEM wheel. 8.5x19, 5x112, 32 mm offset F: 9.5x19 5x112 35 mm offset-R; 71.1 mm center bore. Original cost about 2400 with centering rings and mounting bolts. You would have to purchase the rings and mounting bolts from Tire Rack. I think 1000$ and...

Posted earlier on this subject but recently sold the Supra, Still have the JB4 if someone needs/wants one. It really does work, is easy to install and easy to use. If you want a little more umph in your A90/91 and still keep your warranty, this is the way to go. I never did get the flex fuel...

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 have the stock Michelin PS - noticed a little understeer on the track, went to the PS 4S and this went away. Tires are quiet and have good street wear. Are very close to a track tire on the track but I’m going to go with the cup 2’s on 2nd set of wheels as I need more grip after engine mods...

Do have a question while on the subject of JB4. The sensor read 25% on it’s app and 22% on the JB4. After driving for awhile the JB4 read 4% and sensor was still reading 20-22%. Anyone know why the discrepancy? Also, with the sensor wired into the JB4, do I need to do anything else other than...

I have the JB4 with EWG and flex fuel sensor. I have run Maps 1-3 on the street without problem. You won’t even know it’s there until you step on it. It was incredibly easy to install although did have to lengthen the wire back to JB4 (to short) for flex fuel sensor. I haven’t had a chance to...

I kept up on the track with a supercharged 2010 Z51 with cup 2’s. Shorter wheel base, slightly lighter car, gave me the advantage until we hit the straights. The car rewards good braking and smooth entry, exit from corners. Tracks are different (many or few straights, lots of turns, or not)...

Yes to tracking it: 5 or 6 times. Great in the straights , slow in the corners and rough on the tires. I wanted to go faster in corners and not so fast in straights (more than 150 a little to fast for me on a track)

You brake hard in a straight line, accelerate in a straight line if you want to keep going in a straight line in any high performance car.

despite the early bashers, I think this car is awesome on the track, a little hard to get in and out of for every day driving, but comfortable once you're in. Price isn't bad for all the tech you get. With a little more hp, I think it can be a real contender in this part of the market. Also...

Have a 2020 GR, DOM November 2019. Haven't had most of the problems a few people have reported. No loose caboose or handling problems. Tiny bit of oversteer went away with a set of PS 4S tires, and brake fade went with some Hawk pads up front. Car handles exceptionally well. On the track I do...

Winter storage I have 2020 supra in storage for winter. I have tried two different trickle chargers. They show green to start then give yellow error light after running for awhile. I know the car turns off “nonessential devices” after a period of time (5 min with car locked and key not near...

Thanks, the splice and dice was my thought as well. I’m considering getting it on a dynamometer sometime in May depending on cost and availability. If I do, i’ll Post them.

2020 bone stock supra except for brake pads. No real access to tuner near me so went with the JB4 with the Bluetooth option. Had one on a 2016 Golf with good results. Bought the flex fuel kit as well. Install instructions seem to indicate that for the JB4 to see the ethanol percentage I need...

I can’t say I have seen this at all, not sure why. I run the car at BIR and once at VIR. I tend to brake late and hard. VIR has lots of high speed track leading into some pretty impressive corners and BIR has a long, banked to flat turn from 1 to 2 and then a modest slow into 3 followed by a...

Thanks, that helps a lot. so where is the bang for the buck, if there is one: down pipe or exhast pipes?
