Round 6 of the 2025 Racetreads.com GT Radial 86Cup has us try out a rarely seen configuration (to us anyway) at Buttonwillow with Speed Ventures on an equally just as rare SUNDAY 86Cup date.

On Sunday, September 14th, we’ll be trying out the 25CCW configuration which sends you full speed from Riverside to Grapevine after skipping the bus stop section.

This is also a joint day with our NorCal frenemies in 86Challenge so it’s surely to be an action packed day!

Track day registration is already live via Speed Ventures so sign up now to not miss out!

This day not only has us and 86Challenge, but a couple of other time attack orgs in the SV family are running this day so be sure to sign up SOONER rather than later!
