launching on DR's
 

im going to the track tonight for the first time wiht the new gears and DR's and wonder what kinda rpm i should be looking to launch at??

they are 275/40/17 Nitto 555r extreme drags. right now they are at 30psi but ill be letting air out also

any helps would be great i dont wanna waste a run or to trying to figure out a good spot

i dont have an M6, but i think you are going to have to "waste" some runs to get it down. im sure someone can give you an idea though.

im sure im going to have some not go so planned, but id rather not burn through the tires in one night figureing out how to launch it, i used to launch it at 3500 on the KDW's so im sure its 4K or so

I wouldn't run them much below 25 pounds but I'm no expert on stick cars pressure settings.

I thought you run the Nittos at 20psi at the track?

I had the best results with my Nittos around 20 psi. It didnt help any lower. I got my best launches riding the clutch out from about 4k rpms.

I have to say, the Nittos suck though. They really didnt hook for shit in my M6 car. I wouldn't expect all of your traction problems to disappear with these tires

Oh and btw, don't be worried about burning through them in one track outing. they last awhile. I street drove them everywhere (still do on my SS) and they last about 10k miles, even with plenty of burnouts and track runs, in my experience

My best 60' times with the exact same tire was at 19-20 psi cold. Too much belkow that and the tires will cup in the middleand make the center crown almost useless. I started my burnout by nailing it in 1st and holding it for 7-8 second at about 5500 rpm. Then, I'd let off the brake and take the rpm's up to about 6500 rpm for 2-3 seconds. Next, I would stage and stall up to 1800-2000 rpm and roll somewhat aggressively into the pedal as soon a sthe third yellow came up. Usually cut .02-.05 reacton times. My best reaction time is in my sig ... .001. You really gotta' heat the Nitto's to get them to stick. Some folks say the get 'greasy' when you heat them TOO long, but, i have never had that issue. Hope this helps you.
