Well said!! I was there on Monday and couldn't agree more. In my first session, I was paired with two guys that turned out to have lots of track experience; they pulled away from me when I was in the rear. I also found myself making mistakes trying to catch up. The instructor was great at...

Thanks! I thought about that re: Tail of the Dragon, but couldn’t make the arrangements at home work to be gone longer on a weekday.

My date is next Monday, Sept 28. I'm also driving my GT350 down from southern Michigan. It's a once in a lifetime opportunity with my personal situation to take an extended trip like this with my GT350. That said, I made the personal arrangements needed and decided to leave a day early to hit...

Yep, Forscan.

Yeah, lost about 31 lbs overall moving to the Signature SV902. I haven't had a chance to push too hard on the back roads yet, but the car seems a bit more reactive. My speedometer was off as a result of the reduced wheel circumference on the 30 series v. the stock 35 series. I did...

I have a 2020 non-R and can confirm, as others have, that tires have a large impact on tramlining. My 2020 on the stock MPSC2 tramlined horribly on the rutted roads up here in Michigan. I replaced them with MPS4S when I put my new Signature wheels on in the spring and tramlining is pretty much...

35% 3M Color Stable window tint all around (except windshield). Cool view from the loft above the car at the tint shop.

They are different. When I working on this, I compared some 2019 as-built configurations to my 2020 and found the wheel circumference value at the "old" 726-12-01 location for 2019.

I don't think the 2020's have been mapped out thoroughly enough yet. The double honk disable on the 2020 is also in a different location and one of the guys in the GT500 section stated that the simple programming method on his 2020 GT500 modified the old location and therefore didn't do the...

Hi Jamie - I'd go with 08B4 split between those two locations. 726-15-01: xxxx xxxx 08yy 726-15-02: B4xx xxyy This takes into account your new wheel circumference and the 97.37% scaling factor Ford appears to be using on the GT500. The only thing I'm unsure of with the GT500 is the fact...

Yep, thanks for catching that! I edited my original post to correct.

Check out my post in the GT350 Forscan thread for more detail. Short story is that I have verified that the two bytes that represent wheel diameter are now stored in the above locations. My 2020 GT350 speedometer is now accurate after my Signature SV902 wheel installation. As I mentioned...

I installed my R-spec Signature SV902 last week on my 2020 GT350 (couldn't be happier :rockon:). I stayed with 19" wheels, but changed to 30 series MPS4S from the stock 35 series MPSC2. I stuck with 295 front and 305 rear widths as the MPS4S 295/30 and 305/30 are perfectly matched to the...

Yeah, 305 in the rear. In the PS4S, the 295/30 and 305/30 have perfectly matched tread to rim width for R-spec wheels and are actually the sizes (in PS4S) recommended by Billy Johnson. He says tread width should be equal to or up to 1/2” less than (stretched a bit) wheel width for optimum...

I bought R-spec SV902 over the winter and finally got them installed on my 2020 GT350. I went with modified R-spec offsets to keep the wheels a bit more flush compared to stock R-spec. Just the right amount of aggressiveness, in my opinion. I also went with 50 Deep's titanium lugs to complete...

They are a QuickJack accessory. https://www.quickjack.com/accessories/suv-truck-adapter-kit/ Take the PN from the link above and search on it and you’ll various sources to purchase online. Look for the best deal.

Hi Jaime - Just want to make the disclaimer that all of this is preliminary at this point until those of us with MY2020 start trying this out. The speedometer is based on the rear wheel circumference. The calculated circumference of your new rear wheel/tire combo is 2288.3 mm. I'd use the...

Hey all. As many of you may be finding out, memory mapping has changed significantly for MY2020. For those wanting to calibrate their speedometers for new wheel circumferences, such as when moving to 30 series from 35 series on a non-R, the wheel circumference is no longer stored at 726-12-01...

I would also like to calibrate my speedometer for my new GT350R spec wheels with 30 series tires. It is obvious that the two bytes for wheel circumference no longer reside at 726-12-01: xxxx ???? xxyy by inspection of current as-built data for my car and some other 2020s. Based on some 2019...

Hey all. I have a 2020 GT350 and looks like it shares the same modules as the GT500. My BCM has the same PN and software version as Epiphany's GT500. As we are all learning, many of the previously known memory maps have been changed for 2020. I also desperately wanted to disable the double...
