2025 Racetreads.com GT Radial 86Cup – Round 7 – Buttonwillow Classic 13CW

Round 7 of the 2025 Racetreads GT Radial 86Cup restores order to the Force with us FINALLY doing 13CW at Buttonwillow Raceway this season.

It’s kind of weird how the calendars all work out isn’t it?

On Saturday October 18th, we’ll see just how fast some of you are and see if you’re ready to join the “Sub 2 club”.

Track day registration for this round will be through Speed Ventures.

Also, ALL Speed Ventures events are open for registration for the rest of the year!!! That means Round 7 here as well as Rounds 8 and 9 for Chuckwalla are NOW open. Don’t sleep on it and get some vital track time for our championship run before December!
