Depends on what track you're running. If its a wide open big track ill gear tall. If its small technical track ill gear down for more lower temps and not to have more turque because brushless are pretty torqie

It also depends on the internal ratio of your Touring Car...that can differ by quite a lot. My Losi XXX-S has a 1.83 internal ratio but I think some of the Associated cars are more like 2.5. Big difference!
Losi XXX-T CR * Traxxas Revo Tekno Brushless Conversion * Losi 8ight 2.0 * Losi 8ight-E 2.0 * Corally RDX * HPI Blitz * Tamiya F104 V2 Pro * Associated TC 6.2

With 17.5 in 12th we are already using the biggest pinions available with the smallest spurs we can get our hands on... You will need to overdrive the car to get all the power out of that motor in 12th. Probably talking spurs smaller than 72t and pinions just as big.. You will probably need to change to the old 12l3 'stealth' axle and small diff rings to make this work.
