I don't want to change either at this moment. If I did it would be new PS4s on the rear.
I literally just wanted to know if anyone knew how the newer versions compared.
In regards to my poop comment, I'm finding there is a lack of grip from my front PS4s... But that may just be the fact I'm trying to put 300+ through the front wheels.
Ehh its an UHP summer tyre, if youre giving it full beans in these temps and conditions then not surprising really.
