Can anyone tell me what the red line brembo brakes are like compared to the standard SSV brakes and also would like to know if the red lines brembos are straight bolt up to the SSV or mounting different for the red line?
Yep, calipers are a straight bolt up, and available through Holden.
Then you just need rotors and pads. We've done a few Redlines now, and these are the most popular options:
DBA 4000 Series Slotted $214.50 per rotor
DBA 5000 Series Slotted $536.25 per rotor (then replacement ring is only $338.25)
QFM HPX Pads $110
Remsa Pads $110
QFM A1RM Pads $149
Really depends on what you're using the car for, and how much you were looking to spend. From what I hear the calipers themselves through Holden aren't too badly priced...
