Been perusing the idea lately of getting a set of metal tracks for my Tamiya Tiger I. I've been away from the RC element of the hobby for awhile, so I'm not up to speed on all the after-market manufacturers. Anyway, from what I can gather, the concensus seems to be between Backyard Armour and Impact, and avoid the ones selling on E-bay (Hong Kong sellers). I don't abuse my tank, and just run it at scale speeds, avoiding gravel, sand, etc. Price really isn't a concern, as I don't mind paying for quality and durability.

Is it necessary to upgrade any of the suspension components with the metal tracks? I think it's required with the King Tiger, but not sure with the Tiger I. Guess I don't need to worry about rusting the (manganese) tracks on this one. Also, which one offers faster service? Most of the BA stuff is out of stock, but says they usually ship within 1-3 weeks. Same with Impact?

Thanks in advance for any advice/opinions.
