Turbo – I added where I got the clearance info from, it's for the G37S brake caliper clearance, which I believe is the same as the FX50S caliper. I also added what I know of the line item price

* Almost complete, Turbo is checking what the bolts are in the rear setup
Turbo, if you can also add estimate for hours of install that would help greatly! Also, any chance you're offering to shorten stoptech line bolts if we pay you for labor and for shipping back to us? I'd rather have someone do it who knows what they are doing on something critical as a brake kit even if it means paying for labor and shipping back.

Complete List of G37S/FX50S Front and FX50S Rear Brake kit upgrade:
Caliper clearance required:
47.5 millimeters = 1.87007874 inches
Caliper clearance recommended:
49.5 millimeters = 1.9488189 inches
This is basically the same size as the Brembo GT 4 piston FX35/FX45 kit in terms of clearance. See link to clearance template:

Modifications: Need to shorten brake line bolts by reaming the tip with a drill bit.
(this is applicable to the shorter stop tech bolts that are included with the stop tech lines. if the stock lines & bolts are used then the bolt needs to be shortened more than just reaming the tip with a drill bit, the bolts will need to be cut approx 1/4")
Question:
1) Do both the front and rear brake lines need to have the brake line bolts shortened?
answer, yes, both front & rear share the same bolt issue. the stock akebono calipers are set up to accept a flared hard line, not a banjo bolt, although the threads are the same & the boss is flat making them acceptable for banjo bolt mounting, the depth needs to be accounted for. forcing a bolt that is too long can cause fluid restrictions, leaks or stripped threads... always make sure the banjo bolt can tighten all the way to touching both washers completely flat without bottoming of the bolt on the inner cone, don't force the bolt to tighten if your not sure it's clear to do so
2) If we do decide to purchase stainless steel lines, the Stoptech FX35/FX45 stainless steel brake lines front and rear are the correct to buy? (I can't tell from the part number)
answer, yes, the brake swap is using the stock style 03-08 fx brake lines, so the stock replacement stop tech lines are the correct ones to use
3) Any reason to purchase the rear plate assembly? It's a dust shield? Any other purpose where cutting or removing the old one would be harmful for the car?
answer, the rear backing plate is a shield, it serves a few purposes I guess, one of which is a rear splash shield, when going through a large body of standing water a big blast of sudden water on the inner brake surface of a very hot rotor may cause warpage, assuming it's not raining at the time & both inner & outer are not wet anyway, but just cutting the outer edge off is no problem really... keep in mind that not all cars even have shields like this, I wouldn't consider it a must have at all, actually removing more of the shield & cutting it down to minimum, just to the ebrake assembly can be an improvement in cooling & I'm sure many will remove this as a performance upgrade even... the rotora bbk rear upgrade does not include a new backing plate & they recommend removing the bulk of the extra material there, so no, the backing plate is not necessary at all, it does make for the cleanest most factory like install though & makes installation a bit easier direct bolt on with no trimming involved...

Therefore, OEM quality big brake kit for under $2,500 for all four corners. This also means you have a large range of possible brake pads and rotors in the future by aftermarket companies.
Big thanks to Turbocad who made this all possible.
