I run a 2019 1320 and love it. Definitely ditch the stock Nexen and get some 18 inch MT SS drag radials for the rear and skinnies for the front if you can. Until you can get some, run the stock rears at 22 PSI. Ran consistent 11.92-96 at 1300 ft DA. With the 18s, I ran 11.8 range. With the skinnies, it is hard to believe, but I am running in the 11.7s; with a best of 11.65. I attribute that to weight of the stock tires and rims on the front as well as the drag they create being a pretty sticky tire. Most of my bracket stuff is on an 1/8 mile track here in Bremerton and run consistent 7.54-56, with a best of 7.501 at 1130 ft DA. Transbrake is has been a hard one to get a grip on with how the car is set up. I haven't found an RPM or accurate staging position to be able to consistently leave on third bulb. If I barely stage on footbrake at 1500, I can consistently hit sub .020 lights. On transbrake at 1800, third bulb is at .090-.105. I am going to try to bring the RPM up to about 2500, roll in as deep as possible without actually deep staging and see what happens. I will likely just continue foot braking at races though until I can get the timing right with the transbrake though. Consistency is key after all, right?
