My advice would be if you are going to drop in powerbase and pit pro ect in the track to separate the powerbase from the track and just insert the track piece as it is nearly impossible to stop mdf and bog dust getting inside the pb i had that problem when inserting mine but have changed to the APB and separated this time so no dust got into my powerbase, i also use a low sheen interior paint and find the grip to be great and alot of my scaley cars drive imo better on my wood track without mags and more enjoyable than the old plastic track, the stock rubber tyre work ok but sometimes work better if you try and soften them with some oil and true them, but i make my own urethanes which provide excellent grip and cost bout $1 per tyre. I was unsure before i went to wood but now i am glad that i did and will never go back to plastic
