On 3.69 gears I would heat the tires up until white smoke about 7-10 secs, and launch at 1800 rpm and catch a 60' @ 1.95 with consistency. I hope this helps. PS... Check your rear diff bushings

Yep; 60’ time is critical,as I was consistent 1.94-1.95’s w/heated street tires on stock suspension & 3600# car w/driver. I installed line-loc that really gives a good even heating of rear tires,,,never held against the brakes at launch-just flashed it.
I know with smaller tires & a little less weight would have gotten lower times w/3.69:1 diff....but everything came to a hault when I was crashed out otw home from track (1/21/18’),,,,i really think these cars are capable of bumping a high 11 under right conditions. Though high 12’s were my best with 345/30’s out back & my 275+ azz in leather Touring seats.
Keep at it,,,may want to try removing rear sway bar for some weight transfer & relocating battery to rear.
My run came with a full size spare in back,floor jack,over 1/2 tank fuel...but I was mostly checking launch & traction. I’ll be at it again after insurance gets straight with me.
Good luck fellas!
