I'm back. And yes, I do like the PSSs.
However, I do experience some rubbing, at the fronts, which are featuring the stock sizes (245/35/19) but on the PSSs instead of the stock PS2s. It's only a very slow speed with close to full lock, but it's annoying nonetheless. Ah well, I guess the rubber and / or plastic will give way sooner rather than later anyway.
Haven't noticed any issues at the back yet.
My fleet: Ferrari 458 Speciale / Porsche 991 GT3 (the engine-less BBQ-edition) / BMW F80 M3 / BMW 1M
