Oh Wow Rick!!! That is one beautiful looking finished roller Great news it's a non tilter As you say it's probably due to all that loooooow down brass plate/weight!
I know Steve & Yourself have been using EJ's#15 boots for the front tires but is there a part # for those original K&B hard vinyl ones?
Finally getting round to the subject of rear spongies for the Pittman entries & have got a few sets of Cox & VC greys ready to mount ,thought about using them due to all your tilting issues with these cars on modern Alpha's etc.. It's a tough decision
