I've found the stock laydown conversion parts to work great for most tracks. The dirt tranny is a great tuning option, but definitely not 'required'.
My laydown kit and dirt tranny are on the way.
Question - if for some reason the dirt tranny were to fail, can the laydown/carpet tranny be modified (dropped 3.5mm)? Is there enough material on the bottom of the laydown case to take off 3.5mm? Or is the case machined in a way this isn't even possible?
