Been running Contis ECS 305F 325R on pp2 wheels and love them. I do a lot of spirited driving and dont feel any lag in response as long as pressure is at 35 psi. As soon as pressure is low there's definitely some reduction in steering response.
I replaced the wheels with pp2.
If not used on track they wont affect car but be careful to not overtorque the spacer bolts (max 90-100 lbs)and do NOT use locktite. Only use antiseize between spacer and rotor to make sure they come off easily if you keep them on for a long time.
