Recent new owner of an '11 SHO w/everything. Brakes stand out (not) as too soft and too much travel for a high-per heavy car. My '08 Dodge Magnum AWD has much better feeling brakes and a higher pedal, but in SHO's defense, they stop just as well in normal spirited driving. If U R like me, a geezer from the heel & toe era, you will find the R side of yr foot pushing the go pedal when U brake. Not good. Just move yer foot over.
The '13 reportedly has a bigger master cyl which wd result in less travel (& more pedal force--a good thing) for the equiv braking power. But no one seems to know the ramifications to modify an '11 to '13 brake specs with all the systems, sensors, etc., plus no one wants the liability. Meanwhile will try Stoptech pads F & R.
PS: Mine has adj pedals option (vy desireable for me w/long legs--get better thigh support), but don't know if this option (linkage) makes the pedal feel softer.
Thanks from a pilot who when not up in the air likes my SHO!
