I've done it to mine. For the fronts all I did was get the caliber bracket from racefab $200, elongate 2 bolt holes and trim the rotor dust shields to allow for the bigger rotors. As for the rears, I just cut the dust shields. Doesn't take long to do.
is there any difference between the HSG and the SSG? would the adapters fit on an SSG with the usual modifications (bolt holes and dust shields)?
