Obviously there is a limit between performance and practicality. Now I bet if you went to something like 1mm or even .8mm they might not be "terrible"?
if you whould actualy payed attention the thiknes is .152 and not 1.52 whitch is aproximatly 10X thicker
...and the thiner one is .058 and not .58
and the CR goes from 9.4:1(stock thick head gasket from a 98RS DOHC) to a 10.5:1(with a stock 99RS SOHC head gasket). so its only 1.1 higher, whitch isnt a big enoug(sp?) diff. to couse problems.
