i used to work at a parts store and 4 yrs ago and people said that putting
dustsheilds could affect the warranty of your car because the excess heat
caused by the shield would cause the brakes not to work correctly....however
i was on a site the other day (darn i wish i could remember) anyway
apparently the new shields are warranty friendly so the must have come a
long way.... i personally would use the new ones with the vents...as far as
the low dust pads ? i don't know a thing about their effectiveness... good
luck
if all else fails eagle 1 wheel cleaner A-Z and a nice wheel brush works
great :-)
