I'll be changing the Supercharger pulley as well as performance tuning my 2016 XJL 5.0 Supercharged, and would like to upgrade the brakes for obvious safety reasons. Any suggestions? Is a Brembo upgrade an easy swap? How about changing to the XJR brakes?

 

They are the same part number/number of pistons on all supercharged 5.0, I think you’ll find diminishing gains. It’s not like you are adding a supercharger to a Charger R/T.

I.E. you likely could find a better setup but what are you looking to spend to essentially uprate the XJR stock setup?
