Having put wider tires and better dampers on an M3LR with AB, I concur. I hope the wheels on the new M3P will be something other than 20” pothole magnets, though. 275/35R19 on 19x9.5 (or 19x10, for that matter) is extraordinarily sticky.
The Model S Plaid Track Pack puts 285/35R20 tires on the front and 305/30R20 tires on the back, both 100TW Supercar 3Rs. The rears are 20x11, which wouldn’t fit the Model 3 without aggressive bodywork. But the equivalent fronts (19x10 +35 or so) could fit an M3P front and rear. The odds that you’d break loose 275mm tires even with 750bhp equivalent are… low.
It has been repeatedly noted by many different people that wider tires and better dampers are the two best things that can be added to a model 3. This is because it’s true. Would be great if Tesla prioritized funsies over range and practicality in the new M3P. It’s such a fun platform, why not let it rip…
