I went to have the alignment checked - the settings were a little off. Based on my discussion with the tech the primary reason for the wear on the outside edge is pushing the tires too hard before the tires warm up and the pressure gets up to at least 32.

Lowering the front does not change camber. Only front height and spring pre tension.

How many miles/track days are you getting out of your tires?

I'm at 4k miles, 6 track days and have chewed through the OEM Goodyears and a set of Nitto NT-01s in OEM sizes. All tires have corded on the inside edge first.

I'm only getting 4 good track days before they start to get greasy, depends on heat and how hard I'm driving. Something may be wrong with your alignment. Street driving should not wear your tires significantly at 4K miles, but even 2-3 track days will, so the heavy wear is due to what's happening on the track.

If you're cording the inside edge, you might have too much camber (3.2+ degrees) or maybe your toe is off.

The front tires wear much faster than the rears--1.5x-2x from what I've seen. When your alignment is right, like mine, your front tires will wear faster on outside not inside because that's where the most force is applied during hard cornering--of course. The car leans on the shoulders most on the outside tire and the inside tire is unweighted some, and the camber flattens out so the inside edge is not wearing as much.

I also flip wheels left and right every 1-2 sessions to help even wear because most tracks have a turning bias towards one side. Between days, I flip the tires themselves on the wheels, inside to outside. By doing this I end up with very even wear across all tires until they're done.

Maintaining proper tire pressure is of course important to not overheating and cycling them out before the rubber wears out. Check pressure right after each session and level them out at 32-33 psi hot all around.
