Weight transfert problem on a dragstrip

[blazzin1]

Well if you're not willing to change your wheels, then I think the drag shocks and/or adj. coilovers are about all you've got left to try.

I try lauching slowly, and try faster but it still spin the tire, if i'm trying at around 2500rpm, it start to got wheel up, my tire psi is 32, is there any adjustement I can do on the differential angle like the old G-body ? And I have full adjustable trailing arm, can I adjust them for having better traction?

[JLE58]

Yeah i would go with the adj coilovers then. I think you can get that 60ft alot lower with what you got. 1.8's and 1.9's are rather easy once you learn to lauch with stock power.

i'm not stock, I have ARH headers, Vararam, custom tune, cat back exhaust and i'm running 116 mp/h. I've raced against two supercharger camaro yesterday and they were running slower than mine.

Do you have trailng arms? I didn't see you mention that. If not they are a must. I went from having a bit of wheel hop to none off the line. You can see in that video that I have just a slight hop from 2nd - 3rd but I just recently added cradle inserts so I hope that fixes that.

Serveral Mfgs that make good TAs. I went with Spohn Del-Sphere because I do a little AutoX. Once I watched the video on how the Del-Sphere works I was sold. I think LMP has them for about $200. I've had mine for over a year on my daily driver and they've been great.

BMR and Pfadt TAs are also real popular as well.

yes I have BMR Trailing arm with bearing and adjustable toe rod

Then what tire PSI are you running? Which Nitto tire? I'm assuming 555R. I've heard they really need some heat to hook good but I personally don't have any experience with them. What are your burn outs like?

Maybe you need to look at gettting a line lock and really heat those tires up.

[nuk2]

i'm running at 32psi and my tire are Nitto NT05. I try to heat it normally, extremely and not heating it and I got better result by not heating it. My 60ft was better.

i understand your not bone stock. forced induction, cam, stroker, Is what i mean by non stock. Imho i consider bolts on's a stock car. learn to ease into the gas on your launch dont just hammer it down. slip the clutch very fast dont ride the clutch like alot of ppl will tell you and ease into the gas. Doesnt matter where you lauch if you put the gas to the floor when you drop the clutch. It just takes time! There is not torque Arm to adjust Pinion angle if thats what you were meaning and bring that tire pressure down a good bit and heat the tires really really good.

[JLE58]

tire a nt05 or nt05R ?

[nuk2]

well like I said, I just have ARH headers, tune, cat back exhaust and a Vararam air intake. That's all. tire are NT05

[caverman]

32 psi seems high to me. You should try more in the mid -20 psi range.

True....that'll make a big difference.

Try running a true Drag Radial tire....(NT05 is not, NT05R is)....Or Mickey Thompson just released a new 20" drag radial. That should help your tire spin problems.
