You need some drag radials.

I cannot see your sig on my droid however with your 60' and ET i would say your DA(current track altitude) is crappy.......
Keep working on the launch radials can be a challenge witb these cars. Practice makes habit

That 60' isn't too bad considering you have street tires and 3.90s. I would be more concerned about that mph, that's pretty low especially with your mods. That's a close to stock mph. Is your car running right, any misfires or breaking up throughout the rev range? With an m6 and those mods your mph should be in the 105 range at least.

MPH looks low to me also, considering the mods listed. Best trap I had with shorties, CAI, chokebastard and 3.42 gears was 103 mph.

My went 13.8-9s @ 103mph 2.2 60ft with lts, 4.10s, suspension, and drs. I cant launch a m6 for **** but the mph is up there so i knew it had some low 13s in it.

The track in the only track we have over here in Curacao.(www.curacaodrag.com) I have passes with higher mph but lower ET, as far as i know the car is running fine. I still have the stock exhaust pipe with a crap flowmaster muffler. We had to lower the tire pressure(13 psi on that pass) a lot and i were still spinning. what more can i check out before the next trackday. I want to get into 13.9 with those tires.

I wouldn't lower tire pressure at all with a street tire, if anything do a burnout with 40 psi, then lower tire pressure until you get the most even rubber pattern on the ground. All you're doing at 13psi is increasing rolling resistance ALOT.

You are going to spin on street tires regardless. As stated 13psi is too low for a street radial. With pressures that low all you are doing is distorting the footprint of the tire causing less contact to the track once torque is applied.
You need to either step up to a drag radial and better diff, or stick with the 10-bolt and risk blowing it out or learn find a good RPM to launch on any given track day.
