Appreciate the input everyone.
Thank you DEpointfive0 for the detailed response, answering some questions I was wondering about and haven't even asked yet!
I have seen mention of the loud tire noise in virtually all the reviews I've read, sounds like the GTMat made a nice difference, did you only do the trunk area? Can you remember how (in weight) you used?
How's the reliability been for you guys, other than steering lock issues on the earlier models? I should probably ask this in the general forum...
