I'm currently running an AE B4/T4 81T spur with the AE slipper pads and the stock Kyosho slipper plates...works great. I also have Losi spurs/slipper to use for other gearing options.
The Kyosho slipper is fine, but at 2X the price for replacement pads compared to using AE or Losi slipper parts, this was mainly a cost-cutting move.
Jeremy, are the carbon slipper pads a Losi part, or aftermarket? Do you have a link to them? TIA.
