Also, they recommended checking with folks who are running "cars like yours" to help get answers about pressure, setup, etc. I fully expect to be the only SRT tomorrow so I'm hoping some of you experienced XF autocrossers can give me some help as to how much air to run. My stock conti's say 51psi max load. Should I increase it as the website suggests, or maybe do a run and see? Right now they have 45 psi in them, I pumped 'em up a bit from the 34 I'd been touring with.
Thanks in advance.
I participated in 6 AX events last year with a local Mercedes club in Virginia. I have never run an AX so it took me several tries at tire pressure before I got it right. My 2005 Limited with BFG KDWII tires I run 36 PSI on the street. At most events I found 41 PSI to be perfect.
