    BRM 1/24 tuning tutorial shows the brass weight kit for our cars.  132slotcars has the kits.  Do you know if we will need those weights on our track.  I suspect they are more than our track will need for traction and handling if the sponge tires are good.

    Yeah … that is a ‘goldilocks’ doc – “just right” amount of verbiage – Thanks Marty!

    Randy – your point is good – so basically don’t glue in the weights until a few rounds of practice with sponge tires hints that you actually need weights. Some up front or in the center is highly probable (based on experience in Dallas in 2014-15 with these – but that was a longer track with less tricky turns).

    Steve and I were working on my Sauber and discovered the gears are binding somewhere each revolution.  If the offside wheel is moved out a little the mesh is looser and binding stops but the mesh might not be transmitting power fully.  What AW gears are available and will the pinion and gear be spec’d for our series?  I’m seeing only one or two on various sites.

    I will wait until we get the motor decision too.

    The rules for BRM, including what gears can be used, have been added to the BRM home page.
