Funny that you ask because I just put a set of 2x1.8 on the back of my wheeler last Friday and the car felt great. I had no more choices on pistons and the only thing I had was a piston with just one hole of 1.8. it happened that I had a 1.8mm drill bit and said "hell, why no?t". So, I am running 2x1.6 in the front and 2x1.8 rear with AE white springs front and AE green springs rear, 30wt front 25wt rear oils in my PRSB401 and the car was really good on an outdoor rough-ish really dusty with medium/larger-ish jumps... Only thing I didn't do because I was running three classes and didn't have enough time was to change the center diff oil (thinner). But Ill do that at home before next race.
