OCRC

This past week at OCRC I was able to set a new stock buggy track record of (13/5:05.711) with a fast lap of 22.859. Previously the track record was a 13/5:09 set by Derek Furutani, and then Sean C set a new one at 13/5:08.9 but nobody has gotten into the 22 second lap time range. Anyways I felt this was a good time to share my setup. Warning: It’s kind of extreme due to the removal of some standard pieces to cut weight and add flex.
