Looking to extend my track to a 151", 155" or even 159" (saw a 159" extension kit on a site with the rails and one of two 159" 2-1/8th" lug tracks for $500, sound good)? Let me know if you have anything. If I go with a bigger track what else do I need to change besides rails, tunnel and track? (driver's?). I don't know much about anti ratchet and all the different drivers so help me out!!!
