General Info:

Been looking to do the 350Z 4 piston front brake upgrade for some time now, and finally pulled the trigger!
Just wanted to share some links, because most of these aftermarket calipers come without abutment plates or hardware, which tacks on another $50-$75 bucks.

TRQ calipers includes these parts, and can be had on embay for cheap. I got the unpainted calipers, which were on sale for $155 a pair with hardware and abutment plates. That price has since gone up to $175, but the red powder coated calipers are still down at the $160 range for both.

Either way, stoked to get these painted and thrown on! I already have 6th gen rotors, plus I picked up some wholesale closeout ceramic pads on Rock Auto for around $20, so all in all I’m into 4 piston front brakes for around $175.

Installation Info:

After several small hiccups, I finally managed to fit and bleed the 350z Brembos. The pedals feel a bit soft, so I might need to bleed them again, but overall, I’m satisfied.
For those using TRQ calipers, be aware that I had to grind the inner surface closest to the rotor and order shorter Brembo banjo bolts from CZP, as my factory bolts were too long even with the factory brake lines. Other brands don’t seem to have these issues, so consider the cost of your time and new banjo bolts versus the cost of abutment plates (which TRQs include).
While I was at it, I thoroughly cleaned the inner fenders. It might not be the cleanest 5th gen, but it’s close.
For those curious about this modification, it’s been well-documented. These are knock-off/reproduction 350z front Brembos with 04 Maxima rotors. No adapter brackets are needed—they bolt right up to 02-03 models. However, I believe 00-01 cars need the knuckles drilled out for larger bolts.
