Thank you both for your comment and compliment and yes I am Warren from RacingBrake based in Fullerton, CA.
We have developed and offered a complete brake replacement/upgrade (pad, rotor, brake kit, CCM BBK) for Jeep SRT8 (WK1, WK2) and the latest Trackhawk; so we are familiar and experienced with SUV brake requirement.
I PM the admin asking for becoming a sponsor of the forum, meantime if you have any question please feel free to ask and I will do my best to answer.
As to the front caliper kits, this is how we plan:
1. 4 pot or 6 pot RB caliper progressive upgrade kit* using the stock size (360# x32mm) rotor - The rotor can be OE, aftermarket, or our two piece. (*Progressive means buying just the rotor now and calipers later as needed)
2. 6 pot caliper kits (380x34mm rotors) which can be RB6M calipers or Jeep WK2 calipers - Kits are made for a 100% bolt on installation.
# Although OE front rotor measured as 362mm but per our fitment test 360mm actually fits better w/o developing a rusty lip where untouched by the brake pad.
