I have a 2016 GTPP with right at 9k miles. Up until now it has been just a weekend car, but its now going to become my daily driver.
When the car had about 2,500 miles, I put on a set of very mild 1" drop springs (Steeda Sport Linear). I had an alignment done about 500 miles later.
I aligned it to the FRPP recommended specs, or at least as close as I could get.
The initial reading was -1.9* camber on the driver front, -1.4* on the passenger front. This was adjusted to -1.6* on the driver side, -1.5* on the passenger side. Toe was set to 0.0
The rear camber was -1.9* on both sides with .1 toe on each side (.2 total toe) which is exactly what the FRPP spec calls for so we did not touch this.
I have a few questions. At 9k miles the rear PZero's are, quite tiny frankly, worn the F out. They are 110% bald on the outside, and have just a touch of tread left on the inside. Isn't this backwards of what such an aggressive rear camber would normally show? I had planned on getting the rear camber adjusted down to something more suited for daily driving (1.3* or so) but seeing this tire wear makes me rethink this. The front tires are not noticeably worn at all, and they seem to be wearing very evenly.
Something else worth noting...I've been running a 25mm wheel spacer on all 4 corners. The alignment was done with these in place. I've considered removing them now that I'll be daily driving the car (don't want road debris thrown down the side of the car). In theory, having a more aggressive wheel offset will exaggerate the negative camber, right? Will removing the spacers effectively bring the alignment back closer to an ideal daily spec? Maybe a few tenths or so? Or is this completely unrelated?
So, cliff notes....Why are the insides of my rear tires actually wearing *less* than the outside with close to 2 degrees of negative camber? And do wheels spacers have any noticeable effect on alignment?
Thanks
