Son took his car out with the new trans and suspension. Not a high power car. Mid to High 12's w/auto. 18 psi, 4200 on Two Step. It starts to plant the tire than it spins. A forward move but turning the tire. It has Calverts 90/10's on the front. Not sure on the rears. If the rears are adjustable do you want more extension? thx matt

There is several things to check out... Looser on the extension will help. Make sure the rear shocks aren't topping out on the extension. That will cause the spin. It could also be the front is rising too fast and upsetting the chassis when it tops out. A slow motion camera is invaluable when chassis tuning!!

If you were to call the tire company they would likely not recommend a drag radial for a stick shift car.

Yeah, Drag Radials & sticks do not go together all that well. Radials like to stay planted & are not forgiving like a slick. You can tune it eventually to get it to some what work.

Your only hope is full tight on those shocks and then lower rpm till it hooks. What drag radial you go with?

Having run, and still run a stick shift car, I can tell you that radials won't work too well. If the car hooks, then breaks the tires loose, the shocks are extending too fast. You must slow this down by adjusting them to a higher number. When I race, mine are either on 8 or 9. With that being said, don't expect good short times with the radials. Go to a slick or street slick and you'll be much happier with performance.

He has adjustable shocks and forget about that option. He said they're set on 3 to soften the ride on the street. Brad, They're the MT Street Radial. I'll try to post the video later.

He's leaving about 3 tenths on the table with his short times. So the Bias ET Street would work better?

I think a stiff wall slick would work best. If you want a dot approved tire then a bias Mickey Thompson et street or a Hoosier quick time pro. I how ever feel with a good d/a shock and the Mickey Thompson pro radial you could get a stick car to work. I think you will have a really tough time on the old Mickey radial, I think it will be hit or miss at best.

Hit or miss is right. Raced dad's car with both the original radial and the pro in the same weekend, pro was much better

Didn't read through the whole thread, but has he tried just adjusting the 2 step down to about 3k? Obviously there's all kinds of changes you could make to the car to make it stick, but sometimes the most obvious answer can work just fine. Ultimately, Bias Ply slicks are gonna help a lot, but a small adjustment could make the current combo work. Damn nice looking Dart by the way.
