A052’s will likely replace my NT01’s on my track wheels. Do you have any video? What is the steering response like? I’d be interested in the wear rate. A052’s also seem to run wider than other tires in the same size. Keep us posted.
Hah! We have had the sway bar vs spring rate debate. I’m curious as to how much of the performance is down to the driver feeling more confident because of the faster reaction to transitions and less body roll.
Their is a reason Porsche and M3’s run a staggered setup. Balancing grip over both axles with tires coming up to the required temps for optimum grip.
Unfortunately no video as I broke my mount recently and just haven't replaced it. I threw my tool box on it on accident when I was loading up the hatch, and it was a specific sized rammount with extenders and pieces I bought one at a time. 100$ mistake

I think these will last about the same as the Dz3, longer than the 71r, and less than the rs4, but they are definitely faster! Tirerack talked about them being a tire to contend with the 71r, but these aren't geared for autocross and they don't heat up and grease quite as quickly, so their comparo on a 30s course is useless. Off of the 4 sessions I've run with them, I'd say they take more warm up and are more sensitive to proper driving technique. You can't just mash the brake and expect a proper stop, you have to know where the threshold is. You also can't simply chuck them around like you can the 71r. They take more precision and reward it more fully.
Suspensions, chassis, tires all go hand in hand. It's pretty easy to screw up a great street car by just throwing parts at it, haha. That's why I like to solve things one limit at a time. My brakes are completely toast, so that'll be a project for next year! I'm looking into the powerbrake setup you've got but can't seem to find any sellers. I'm also looking into the stoptech competition line or trophy series. Trophy is cheap for the 328mm comparatively!
For reasons of being able to rotate tires, I'd rather run a square setup and adjust rear rotation with less rear toe in.

No argument here. My reasons for wider front are about heat maintenance. If I ran 255 square I'd have the same issues as with 235 or 245 square, just at a later point in the session. The stagger has less to do with rotation and more to balance out when the tires are fully at temp and how much heat they can hold/expel. 60:40 distribution + fwd + braking + 300hp hates the front wheels, and I'd rather not run 40psi + and 1000lb springs if I don't have to.
If I had to run square, I'd probably go for a very stiff front bar, stock rear, -2 rear camber with slight toe in, -3 front with slight toe out, and a square spring setup. That's just based off of my personal "feel" with this platform. I know a guy that runs close to that with square tires on his older a4 race car, which has similar chassis characteristics to the mk7 gti. Granted he's on 1300lb springs...
