^ i'd actually advise against that, even though it's MIJ, the stock trem is still poor- it'd be actually cheaper to get a 550 (more than likely), and then you wouldn't have to fork out for a new trem.
not to mention that the lo-trs (unlike the lo-trs-2 on the korean ones) has the wrong size studs for a direct swap with an OFR, you'd have to do a little drilling too.
