[QUOTE="rw95gt, post: 10041380, member: 53649"] Hey Dwight, thanks for the advice. I feel the same way. The main reason I ran at 19psi was because of sway on the big end. It's a little on easy to be moving around going 100 plus. I had 28" et streets on the rear my first 2 times at the track. They had way too much sway for my comfort. The 28" et streets also took away from gearing way too much. I was going through the traps in 4th at around 5000 to 5200rpms. I was leaving a lot on the table with the 28" so I went down to a 26" tire. My mph jumped from 116mph to 120mph and I dropped .24 off my et slips(11.94 at 116 to 11.70 at 120). The 26" tires also don't sway nearly as much on the big end compared to the 28" tires. Next time out I will work my way down in tire pressure and my rpms up on my launch. The track last night was a mess and I felt rushed so I didn't mess with tire pressure much. Hopefully next time out I will cut a very nice high 1.5x 60ft. That would make my day if I did.
