SCX raid cars run better than you might think without magnets. The tyres have reasonable grip and the 4 wheel drive helps. They will circulate without drama on my wooden track, not super fast but very little sliding about. Despite their large size and high centre of gravity they don't roll over unless you do something fairly stupid. Aftermarket tyres would undoubtedly make them better but I don't know anybody who makes  such a thing.

Not much mention of Avant Slot in this thread:
   

75mm drop arm, 25k motor and will cope with all the SCX obstacles. Much better performance than either SCX or Ninco but just as hard to find and top dollar when they appear on eBay. White kits currently available from Pendle's at reasonable price though. LINK

Of course you could go potty and get one of their six wheel drive trucks LINK
