not making a valid argument here, track layouts and carpet (brand new/ reused/condition) is not the same year to year at any major race, also technology changes in batteries, chargers, motors, car chassis, etc. imo it is faulty to just single out a motor using year to year results.

i went to liverc RC and looked at 3rd round overall qualifying. in 1/12th scale there is a 3-4 lap spread between each motor class Mod, 13.5. and 17.5. a huge difference of 7-8 between Mod and 17.5, so not seeing stock here as being to fast, in comparson to TC where you might have a point where classes are created on a whim.

there is a 1 lap separation between TC in order....MOD, 17.5, 21.5, USGT (21,5). there is a 6-7 lap spread between 25,5 TC AM and TC mod.

if you can't find a valid point or argument on what is occurring in TC with speed and lack of difference. then there is a valid argument to be made that 17.5 and 13.5 are actually to slow for stock and super stock 1/12th scale and a return to 13.5 stock may be warranted along with super stock 10.5 boost which is occurring in other countries.
