OWNER CERTIFIED MODIFICATIONS ever herd of this ???. Any ways aparently if your model of car eg AE92 has a base model carby with no front sway bars and solid front disk's (pov pack) and a sports model sx/gti you are allowed to change parts over WITH OUT an ENGINEERS CERTIFICATE,say change the brakes over, the alloys, the suspension to run a front sway bar and the motor??? is this true???./ I herd it from a guy at work whom does pink slips. Now my question is did the AE92 4agze corolla come into australia with out being a import as a australian limited edition? if so wouldnt that mean we wouldnt need a engineers certificate ???. IF SO WOULDNT ALL THE AE92 OWNERS WHOM HAVE DONE A GZE CONVERSION NOT NEED A ENGINEERS CERTIFICATE ???. Any help would be appreciated.
