Most people have a terrible time hooking up radial slicks on a stick car.

We ran Hoosier bias ply tires on the G/S Camaro we had.

What front springs and shocks are you using?

What bushings and ball joints?

What clutch system are you using?

I strongly suggest that you talk to Mcleod tomorrow about a complete Soft-Lok setup for your car.

You can spend more money, and you might be a little quicker. But most are best off with the Mcleod Soft-Lok.

Before going too crazy put some stick tires on there and try it. I use Mickey Thompson 3056st's with great success, but the most important part is to make sure the tires are bias ply for a stickshift car, not an automatic.

You said ram 3 finger pp. What size and compound or type disc? Any counterweight on? How much base pressure?

Most stick racers are running the same tire Jim stated, it is a stick tire. I don't think anyone in Stock has had success making a Radial work. Is this a new clutch? Did it come from Tim Hyatt? Or did you buy it from Jegs or Summit? Base pressure should be less than 300.

With your setup, leave at an idle, or around 2500. You might have a chance then. Need to go to a bias stick tire when you wear yourself out with the radial. Then you will find it easier to make the car work. Good luck

Your running a 5.38 rear gear with a 325 hp BB Camaro stocker? To even try to get radials to work on a stick car you would need low clutch press. I would run a M/T bias stick tire with that combo. gsa612
