with metal tracks you really must think about upgrading the idler tensioning system...Tamiyas original simply cannot cope with the extra stress.
The best ones to get are Daryl Turners spring idler system you can email him here-

the idlers upgrade is a an absolute essential, If you get your Tiger on rough terrain it will throw a track in 30 seconds without them.
He doesnt have a shop and makes them up himself, there are pics of the system fitted to one of mine in the tanks forum here -

The metal tracks add a serious amount of weight and the tank will now have difficulty with any incline more than 40 degrees (smooth) and 30 degrees (rough terrain). There are many other problems that raise their heads dependant on where you run your Tiger. Other strain points are the drive shaft barings, to prevent excessive ware after market brass support add ons are available from many webdealers (check out US dealers first as the dollar is real good at the moment).
Thats a fine lookin Tiger ya got there.
