KOS cars had trouble, yes. A few guys need radial prep which is not practical.

As for me, can't really say. I bought a new converter when my guy said he didn't know when he would have mine fixed. Well they dropped the ball and totally missed the part where I have a nitrous motor and even suggested a gear change. Both were gauranteed to cause trouble.

That said met some great people, great breakfast Saturday morning.

Blew me away the girl working staging lanes couldn't see numbers on cars or "PT" on the window means pro tree. Paid good money to test Friday night. Most tracks have a protree lane, just a suggestion.
