You will need the GXP Calipers and Brackets.
Got mine from car-part.com
GXP Calipers are dual piston and aluminum (much lighter)
GXP Brackets are much larger
GXP Rotors and pads.
I went aftermarket - Slotted and Dimpled Rotors from performancebrake.com and EBC ceramic pads
SSEI rotors 11.7" GXP 12.7"
Pads almost twice as big
Longer GXP hoses and 4 smaller GXP bolt from bracket to spindle # 89047763
First jacked up all 4 wheels
Took of all 4 wheels
Take off caliper, bracket, and rotor
Install Rotor and bracket -- bolts can be a little tricky (must line up shank)
Install Caliper (hose to short)
Install longer GXP hose
Had to modify hose bracket - they are keyed - ground out/off key (they weren't in the right position and kinked the hose for me.
Need GXP Rear Calipers (same # as SSEi, think its the same caliper)
GXP rear Bracket (very close to same, sits half an inch higher for larger rotor)
SSEi 10.7" GXP 11.7"
GXP rear rotors and pads - performance brake.com gave me ceramic pads for $20 with purchase of rotors
Take of caliper, bracket, and rotor
Install rotor, bracket, caliper - with SSEi hardware, used same e-brake bracket (hardest part was switching the e-brake cable)
Now bleed them out
Went for a ride to seat the pads, was slamming the brakes @ 40 4-5 times. She stops like 50% shorter then last week when doing it with the new SSEi pads. MUCH BETTER !!!
