Needswings pulley saver kit feedback
Get it. You'll sleep better.
I got my PSK installed yesterday by the fine folks at CW Performance
while I was in for some other service.
My feedback so far is positive. The parts fit perfectly, the idler pulley doesn't look like it's being spun into oblivion, and the belt/pulley whine is a lot quieter at idle (I suspect that the previous owner's decision to add an Evosport pulley was hastening the demise of the existing belt.)
Now whether or not it will actually prevent any failures is something that only time can tell -- but I definitely feel a lot more confident in driving the hell out of the car than I did before...
... and now that my IATs are back down to normal (after Curt & co. helped undo the previous owner's stupidity), I'm looking forward to doing just that.
