Yes. File a charge back with your card company that you ordered everything with.


The reason you can't hook up is because you have the nitto's. The best thing you can do is buy a set of non DOT slicks.



Also be sure your posting in the correct section.

I love Bandimere Raceway! It is awesome at night! Another thing you may want to consider if you are not getting traction, is to lower the air pressure in your front tires. It won't be as efficent as slicks, but it will give you better traction than what you are getting now. I know when I have raced at Gateway over in IL, I use to drop my PSI down 20-15psi range, it seems like you are almost running flat, but with that lower pressure, you are putting more rubber to the ground for contact. Just remember to pump them back up before hitting the highway

ZZP has had some issues of late no doubt, but just keep sending them emails and phone calls, hopefully they will get your issue resolved.

Thanks for the info,the class i run at bandimere requires dot tires.I think i might try putting my street tires back on and lowering the tire pressure.

Has anyone ever heard about backing up and them lightly jumping on it to engage both frt tires? that seems to be my biggest problem is that it only spins one time when i launch.

I finally got a call back today from zzp after 3 more calls, i think they are going to take care of the problem.

thansks again for the info i race this friday,we"ll seen if i can do any better.Hopefully the track conditions will also be better.
