Looking to replace my 163/2.6 track that started having small pieces of rubber come off on the underside right where it runs on the rear boggy wheels. I’m looking at the Epic 280 part# 9407M 162x15x2.8, 3.0” pitch track. I know the stock track is a 2.86” pitch so thinking I would need to change drivers? Was thinking about going to the Avid extrovert drivers along with anti stab anyway because of the turbo so I don’t have to run the track so tight. If I went this route do I have to trim the rails (hoping not)? Does anyone have any experience with this track on a axys or a similar setup? The other question rolling around in my head is how much a setup like this may change gearing with track weight difference, track pitch, ext. Probably just have to do some tuning to get it back to what I like for gearing. Thanks in advance for thoughts and ideas.
