Hey guys. I have a FBO DCT M4. Keeping the car on the stage 1 OTS BM3 map for now— but will be doing crankhub very soon and then going custom on e85.

With that being said— i need some new rear tires! Currently on corded Super Sports on the OEM sizes. Fronts still have a little life in them.

should I go on R888R already or upgrade to PS4S?

If i do PS4S:
1) do i need to get new fronts or just get rears?
1) how much wider should i go front and rear? (255/275 now). How wide can i even go on a stock suspension setup?

Done a good bit of research, but haven't gotten conclusive answers.
