I have the Rside Hood spacers from Kspec? Anyways, I have had them on for a couple of months now with no preoblems except for one. Sometimes to pop the hood I have to actually lift the lever and grab the hood by the windshield to "pop" it. I think that the spacers shift a little more weight to the front and the spring is weak (hoods wiegh 45lbs.).
I dont know why this would create a problem with water.
i insaleed them and the look sweet. As for being rice, i don't think so. It adds some attitude and is a popular thing to do in korea. i was worried about rain because i have a short ram, and any water traveling down the inside of the hoodcould possibly hit the filter. If it is raining hard enough and is at the right angle.
