ha, you guys are too funny
guys, I really appreciate the praise, but I really didn't do anything so overwhelming here to be honest... the brake lines are a pretty simple thing & just require slightly shorter banjo bolts, most everything else is just sorting out hardware & misc parts... mostly bolt on. the biggest "custom" thing here really is the ball joint seat. I did this cad design & redesigned the ball joint seat with emachineshop.com really cool software & ordering system there for custom manufacturing parts... I designed it & Joe ordered like 50 pieces for the first run. he will now have an exclusive on these retrofits mainly because of this, joes been really great to work with & it's cool that he's gonna have these exclusively as far as I'm concerned, he also gives the best prices too so it's a good situation there. I won't share this ball joint seat design with anyone as joe has been good to me. it also wouldn't be cost effective in small quantities anyway so it's really best to just get them from him anyway.
as far as aftermarket rotors, the fronts are the exact same rotors as the g37S, so I'm sure these will be available soon... actually both calipers & the front rotors are exactly the same as the g37s. The rear rotors however are a bit different from the g37s, the parking brake is larger on the fx than the g37S, so g37s rotors will also work in the rear, but the parking brake won't. if your willing to sacrifice the parking brake then g37s rotors all around should be a solution that will come soon... however, to get fx specific rear rotors aftermarket performance may be a bit less in demand... who knows if & when they will do the fx specific ones out back...
I may try to retrofit the g37s parking brake when rotors become available for them, but this will be custom work & not a matter of just different bolt on parts really... I have already driven the fx on g37s rear rotors for at least a few weeks so I know it will work, just not compatible with fx parking brake shoes...
one thing I can say is the factory rotors are HEAVY... my rotora rotors are much lighter. funny thing is, the new front rotors are the same dimensions as the rotora rotors, so I can actually use OE fx50 front rotors with my rotora calipers, but it won't work the other way around. you can't use the rotora rotors with the new fx calipers cause the rotora 2 piece rotors have a larger center section & the fx calipers hit it, but the 2 piece design with the aluminum center hat of the rotoras are much lighter, I wish they worked, that would have been the ultimate retrofit... I'm pretty sure performance rotors will come soon for the g37s though, be nice if a 2 piece rotor became available, but for the price of these brakes a little extra weight in the rotors is a fair trade off really...
