I am doing the SRT brake upgrade with 20/19 iForged as we speak now. The lead time on the wheels will dictate when I get all the parts (Dan at Viper Specialty Performance is choreographing all of that), but the $$$ numbers are as such:
Euroteck rotors (the best looking IMO) $1649
New SRT calipers $1764
EBC reds $218
Big Brakes bracket kit $795
Big Brakes stainless lines $260
Big Brakes e-brake kit $545
Big Brakes spare tire adapter $120
Throw in some $ for shipping and we'll call it $5500 even.
