So I've had my RCF for a little over two years and have a bunch of mods so I wanted to see what it could do. Took it to Auto Club Speedway in Fontana, CA on Sunday 11/5/17. Ran three times and was in the 14s each time. Horrible traction off the line. Could not launch for the life of me and spun for 3-4 seconds all through first and second until it finally took off. Had the car in expert mode using manual mode. Ran MPSS tires 295/30 20. Had the PSI @ 25lbs. Although the 1/4 mile ET was bad my mph was still solid @ 112.56mph. If I had a Drag radial or figured out how to launch without lighting up the tires im sure it would do alot better. Once it caught traction the car accelerated very well with less track to use with the bad launch. Ill try again once I get some Mickey Thompson Drag Radials. Im a rookie and the cars that beat me definitely weren't faster, just better at launching and were a quarter down the track before I left the tree haha. Here is the slip and a little video of my learning experience. You can here the tires squealing all the way through the O'reilly poster.
Now about your traction problems...not sure since I don't have your mods and have never 1/4 mile run my F but I think maybe you might launch better in sport with traction control on and let the car shift itself. When I ran 1/2 mile from a dig that setup work best for me and I seemed to get a very good launch every time with very little spin (1st & 2nd).
Your car is solid! Just look at your MPH. You seem to have the tree down with a great RT of .012....Your right your 60ft is killing you (like most of us). Are your MPSS worn? My experience with them is once I'm to the 1/2 way point on tread forget it. Your definitely going to get the car in the high 12's with a set of Mickey Thompson tires.
Get the tires and head back on 11/19 for another round of street legal drags..(Auto Club Speedway Fontana)
I would say, calculate your circumference using online calculator of the 20 inch wheel/tire combo and factor in the weight of the wheels. Bigger circumference and weight must be hurting your off the line acceleration response. The fact that you are having a slow off the line acceleration also is a tell tale sign since bigger wheel/tire combo means taller gear ratio, which manifests itself in slower rev-up off the line to redline in 1st gear. Then, if your wheels are heavier than stock, that has impact on acceleration. Maybe, try going back to stock 19 inch wheels with a sticky set of tires and see how it goes.

I have a 2017 GSF and too took my car to the track for the first time last weekend. My time is on the right. Ignore RT, I could've sat there for a minute and it wouldn't affect time.
Burnouts do not do anything with the Michelin tires. Not sure why anyone would suggest that.
Sport + Mode, traction control off, TVD normal mode, manual mode. NO BURNOUT, unless you are using drag radials. I didn't do too bad for my one and only run and just purchasing my car a week and half ago...
Also suggest brake torque launching at 1.5 - 2k RPM

“burnout do not do anything”- coming from a guy that did 2.2 60’ and 13.3 1/4 mile...hahaha

Not bad for purchasing my car on halloween and only putting 100 miles on my GSF and running it once right?
I’ve ran my Viper at the drag strip and even had a 600 rwhp Cobra and ran it at the strip dozens of times!
Burnouts on super sports heat the tires up but do not make them stickier, they are not made of the same compound as drag radials. All you’re really doing is wasting tread.
Infact, you’ll make them greasy by doing a burnout because when you heat super sports it breaks down the compound and releases oil.
