Default M/T DR didn`t work!!!

Went to the track saturday night happy with my new M/Ts hopping for low 12s. I ran a couple of 12.8 ,12.7 , 12.6 with a 2.1-2.2 crappy 60`, my best was:

R/T .260
60 2.006
330 5.464
1/8 8.212
Mph 88.98
1000 10.640
1/4 12.598
Mph 112.43

I am pleased with the times since my mods are only LTs, tsp true duals, spec3 + steel flywheel and a lid, adjustable Tq arm.

spare tire and Jack + rearseat where taken out.



I was very dissapointed with M/Ts ,they didn`t hook as I thought , the best I could do was 2.006 60`, I did almost 8 passes with a tire pressure between 22-15 .

does anybody had any difficulties getting those MTs on a M6 under the 2.000 60`? any comments?

MT doesn't recommend those for manual trannied cars, but I know several guys have still cut 1.6x short times with an M6. The problem isn't the tires, its something else.

2.xxx 60 is bad even for street tires.

Work on the launches.
If you were spinning then you werent doing a long enough burnout.

15 psi with a GOOD burnout should get you some 1.8 or quicker short times. the tires love to be heated.

i cut many 1.6x 60' with my stalled automatic on these tires. i have next to no susp. mods...only sfcs, lcas, and !frontswaybar.

i totally disagree with the above post. 21 psi and a small burnout. for the radials to work, you cant shock the tire. you will have to slip the clutch adn that tire WILL hold. if you are dumping the clutch or the track is trashed, you will spin.

many many many of us have gone 1.4 60' (myself included) and under on this tire.

Yeah, I cut a 1.60 on M/T drag radials w/ an M6, stock shocks, and lowered suspension. These tires are good. Something else is definitely wrong. Could be a loose nut behind the wheel Sorry, I couldn't resist...

Impressive but certainly not the norm. MT does not recommend these for stick cars. If you're making decent power and dumping the clutch they won't hold, at least not consistenly.

Well, I got away with it because my clutch was close to being gone and slipping alittle. Now I have a stalled a3 so they don't hold very well. Thats why I'm going w/ Hoosier QTPs.

I've had good luck with these, best of 1.52 60 foot on 275/60/15 size. 8" rim, 17-18 psi, 2-3 burnout and they hook! As mentioned above by a few, stick cars need more finesse likely as opposed to an auto.

well the way i did it is setting the tire pressure at 15 psi( thats for the best run) and did a reasonable smokey burnout , steped on the line and holded the clutch at 2600 rpm and slipped it .( I tried dumping , but 60` was worser) .

stock springs and shocks too.

I agree I run 22psi small burnout and cut 1.32s on spray the best of a 1.44 on motor.

Even when I had stock suspension they hooked very well for me. Thats when I got my best 60 ft of a 1.32

If I can find one of my burnout videos I will post it for you. Not much of a burnout is needed with MT DRs

I have to agree with everyone else, you have something wrong with your setup, or doing something seriously wrong.

I don't agree with lowering the tire pressure. I've seen 1.4x 60ft's out of mine at 20-22psi. IMO, they got worst with less air.
