I have a 2.0 truggy and I installed the Kink Headz extended mount before the truck hit the dirt. I have ran this mount for the last season in a 1.0 truggy and I love it. Keep the plastic braces front and rear and you will have plenty of flex. The alum braces takes a lot of the flex away. Depends on your driving style. I like all the flex I can get but there is no need for flex at the clutch bell it can not tolerate flex for long. I have no problems with the starter box. I have used the losi box and recently the ofna truggy box (best box on the planet). Just my 2 cents.
