Heading out for track day over next couple of weeks and notice that the smaller most outer groove of the PSC2s has maybe 1.5/32s left, while the two large inner grooves have 5/32 left. When the car was new I wasn't paying attention to see if that outer groove was more shallow to begin with vs the two inner grooves. Is that outer groove of the 3 supposed to be more shallow than the two inner ones? Thx.
