It’s not a bad kit. For guys our size 6’4″, it’s a necessity. Even for those much shorter I do believe it gets you in a better position for driving on the G5’s as the headliner is insanely low at the windshield.
Definitely worth it but the installation is a SOB in ACR. At 6′ 1″, wearing a helmet my head did not clear the headliner. The kit now makes it perfect, plenty of clearance and no longer staring at the visor!
