Very cool. Thanks.

Lower gas prices now.....

Is anyone using tire screws in their radial slicks? I know that many of the street drag radial guys are staking their tires, but what about stock/superstock cars? I had one guy tell me that his 30x9 radial slicks actually slip about 1/4" of an inch each pass. Is anyone else experiencing this? Thanks!

When I ran the radials on mine with the auto they would not slip but when I converted mine to a stick with the bias ply they would turn about a 1/4 inch per run. It killed me to drill the Bogart wheels but I had no choice.

That's a really nice product for $65+/- !

Jeff,
thank you for the nice comment. We constantly question and scutinize our manufacturing process to be able to offer products at an affordable price. Products are no good if people have to spot a loan just to get their hands on them.

Bob,
thanks for the feedback. I now have to ask this. Why won't a radial slick work on a stick car? Can't clutches be adjusted to work with this type of a tire? This has been a source of confusion to me for quite some time. I'm ready to be educated. [:-veryhappy-:]

A stick car hits the tire harder as a torque convertor offers some amount of "cushion" to the hit. The design of a radial with it's wrapped plies offer a spring motion when compressed excessively. So when you hit the radial, it recoils, bounces and then the slick never recovers. A bias slick gets hit and doesn't coil back, it stays planted.
Or so the theory goes....
Possible cures for this problem are stiffer shock settings, softer clutch settings and lower launch RPM's. The problem here is lower launch RPM's typically require stiffer clutch settings (base pressure). So two of the possible cures contridict one another. Another avenue to test might be bead-locks. That increases sidewall stiffness and may slow the spring motion. That's just a theory I have, don't know, haven't done any testing with radials. There is also a definite weight penalty here.
My best guess as I write this is extremely stiff extension settings using a KONI controller to soften the extentsion in gradual increments; measured in milli-seconds. Way beyond my level of application and proper testing!

Jeff,
thanks for your insight, it was very informative. The dynamics involved are really interesting. I'm sure that there are alot of people out there who are trying to figure out how to make this work. Challenges such as these are what makes drag racing fun if you ask me. Take care.
