Fixing outer shoulder tire chunking: Bridgestone RE-71RS's, Michelin PS4S's, or camber?

[play150]

Hello everyone,
I've been getting tire chunking or peeling from using the P Zero PZ4s on the track. Would switching to an extreme summer performance tire (200WT) such as the RE71RS's help? In my last car I also used the Michelin PS4S's on the track, but the car was also a lot lighter than my M3P.

I've been avoiding the 200WT tires as I hoped to just daily drive the summer tires, bring them to the track 1-2 times a year, then switch to winters when it gets cold. But I'm thinking I could use the Michelin CrossClimate 2s year round and just switch to a 200WT tire for the track day. Do y'all think this would help the shoulder chunking?

I also have stock camber FYI, not sure if this means that changing the tire won't help with the chunking. I was also wondering if I let too much air out from the tire to cause this! (i.e tire rolling onto the sidewall)

MASTER THREAD: Comprehensive Road-Course Modification Guide — Optimizing the 3 for the track

To begin with, the Model 3 is a decent HPDE/Track Day car out of the box. However, there are some concerns if you are planning multiple events a year or participating competitively. There's also a lot of options for making your car faster. I wanted to create this guide to shed some light on the...

Race-centric tires may be more resistant to chunking, but will still wear on the shoulder very fast (and give sub-optimal traction) without more camber.

RE71RS's will help.
PS4S's overheat and start shedding chunks of rubber on track.
More negative camber upfront is all but required.

Sure, why not.
When I lived in TX, I used to run rain R-comps all summer long, including on track. Yes, extra heat cycles reduced their absolutely grip, but not changing wheels & tires in 100+F degree heat was a welcome trade-off.
Regular performance summer tires were my "winters" ;-)

Michelin CrossClimate 2's are all-season tires. They will suck in all seasons. Is that really what you want?

You do need significantly more negative camber upfront for track or for autoX. Somewhere north of -3.x degrees.
Don't fall for some vendors claiming "easy" camber adjustments between street and track - changing camber effects toe. By a lot. You will destroy tires in no time if you neglect to align the car after a camber adjustment.

Either way, you can't get enough camber with stock camber plates. An aftermarket product, like the one linked below, is what you want:

On a Model 3, top hats won't help with camber. You would need FUCAs for that.
