The trouble with wheels/tires……….
In spending a couple of hours running the BRM Group C cars today with the goal of “rubbering in” the track I found there was little if any improvement to the cars grip. I called Alan at 132slotcar to get his input and learned that the BRM wheels/tires I have spec’ed in the rules are a hard compound of foam and will only hook up once the track has many many hours of running. The Scaleauto ProComp 3 tires we used to run are softer and would hook up better but Scaleauto no longer makes the replacement BRM wheels. In looking for a suitable option tonight I discovered Scaleauto produces a wheel/tire that is .5mm wider (16mm vs 15.5mm) and 1mm smaller diameter (27.5mm vs. 28.5mm). Unbelievably, I had mis-ordered a set of these wheels months ago and have them in hand to see just how they will work on the car. I mounted them to a Porsche, Mercedes and a Toyota and they fit perfect on all three. The lower profile also allows the car to sit lower in the rear and that can do nothing other than improve the cornering. I will be taking the cars to the track on Sunday to see how they work. I will update the forum and change the rules if needed.
