Correct bolts for Corbeau seats?

[TroubledSoul]

Wasn't sure whether to put this in here or club motorsport but I am trying to figure out which bolts to buy for mounting my Corbeau Pro Series seats. From what I've found out, I am after M8x1.25. This is for side mount rails.

My dilemma is over bolt length; 20 or 25mm? And tensile strength; will 8.8 grade bolts be OK or should I be looking for 10.9 bolts?
