A few quick questions about PPIR:

1) Is it hard on tires?
2) How does the grip compare to High Plains?
3) Do spring rates that work well at High Plains also work at PPIR (videos of the track make it look a little bit bumpy)?
4) Is there anything going on Friday to allow those new to MRA a chance to learn the track? I can't find anything on their website or on MotorsportReg, so I figured I'd ask here.
