Coupe camber specs are slightly more aggressive (.5 degree or so) than the sedan. With toe zeroed out, tire wear is minimal.[/

Just checked my alignment specs and was pretty surprised to see my camber as negative as it is (although I am admittedly not an alignment expert). What do you guys think of these after specs? Do we have stock front camber adjustment? Should I not be this negative?These are the specs after getting my new steering rack and NVA tie rods installed. At least it is all green…
This is inline with mine, except that my front camber is slightly higher, my total toe is 0, caster is a degree higher and my rear camber is at the top end of the coupe alignment spec. Yours is in the middle.

I’ve never really felt a difference from stainless lines, so I decided to just leave as is for now, Plus, this is already a big job and I figured I needed to cut my losses…

My new window trim and weatherstripping is starting to come in from Amayama, so I figured the better use of car funds will be to get that done first.

When I had my calipers painted I checked my brake line and they still looked new. I checked online for when to replace brake lines and the responses were all over the place from every 10 years to decades. Not sure. I may do it the next time I get a brake fluid flush.

The Z1 calipers are Akebono, painted red and screen printed (decaled?) with the Z1 logo, but still OEM.

And I'm assuming your 18x7 wheels are also OEM sport wheels for the Sedan.

So yeah, shouldn't be any question about fitment.

My originals were pretty gross after 13 years and 50k miles. I suspect they were fine and functional, but like I said, they looked horrible, rubber and metal was no bueno.

Since I was replacing calipers at the same time, I didn't notice any change in braking because of the SS lines.

I think at the end of the day it was $180 for peace of mind. And opportune timing, what with all the brake work already.

Agree. OEM Sport Wheels are the goto for BBK setups.

Your car spends most of its life garaged right? I was expecting mine to be deteriorated and gross, but they looked fine. I should have snapped pics when I was in there inspecting and cleaning. Nonetheless, makes sense to replace soon as a preventative measure the next time I do a brake fluid exchange (every 2 years).

Are you 100 percent sure they are oem? I'm looking to get some in the future if they are genuinely oem. I bought some red Powerstop calipers which aren't oem, but look exactly like it could be. I went through 3 front sets before I got a pair that were molded correctly enough that would allow the pads to fit inside. Had to get the ceo of Powerstop involved. My rear Powerstop caliper seized up in about a year. Don't ever get the Powerstop calipers y'all.

No, actually I'm not. I assumed Z1 (and PowerStop) tapped into Abebono to source unfinished calipers in bulk. Are there actually knock-offs, from a knock-off casting?

It does. This morning was the first time I've driven it in over a week.

The first four years or so it got driven a normal(-ish) 10k per year, including salty Western NY winters. So maybe that, IDK.

Yes they are aftermarket.

So for all practical purposes, they are identical, simply not manufactured by Akebono?

Yes. They aren't Akebono's. But 3 in a row the pads wouldn't fit inside the caliper. The 1st one came from Amazon and the other 2 directly from Powerstop. The good one the CEO had to have the warehouse manager personally inspect the calipers before they sent them to me.

As a matter of fact, the Z1's are also aftermarket. This is the first line in the description. "Similar to the factory Nissan and Infiniti Sport/Performance model brake calipers"

Getting closer.

A couple of comments:

1) Z1 calipers are forged vs Akebono cast and Z1 says that their calipers have “the same size limitations as oem akebono” lawyer speak for they are the exact same size lol

2. The Z1 bolts that came with the 10mm spacers were too long to use OEM lugs. A bit surprised at Z1 here. They had to trim the studs down a bit.

3) The installer suggested I should have done the lines! Not necessarily due to functionality, but to complete the project. He said we will get it next time. Haha.
