I posted this awhile back, and didn't get much response, but i have to buy a new set of tracks for my S300 w/vts track setup on it. Prowler has what they call the EXT line: http://www.prowlertracks.com/rubber-tracks-prowler.htm#compact and i am seriousely considering trying them. Called McLaren to get price on nextgen tdf's (as we have them on our mt55 and t250 already) and they won't have any available from 90 days. Apparantely they have to wait for the mayflower to come over from china! I have to get new tracks within the next 2-3 weeks, as one of my tracks on my vts broke a steel belt late last fall, and i haven't dealt with it yet. But spring is upon us soon, and i need this thing moving. Any input??
