I've used Grade 8 in the past on many cars. You'll never have a problem. That said, I sourced all 10.9 for this project. This time I mostly focused on matching all hardware coating types so as to avoid premature Galvanic corrosion.
A FWD spindle holds a RWD caliper about 3/16th closer to the hub.
The mod involves removing that much material to allow the rotors to clear the calipers (cold clearance isn't enough, rotors expand more than you think).
So since you're using RWD adapters you can either use a 3/16 smaller rotor or grind that much material off.
If you're OG enough I'm sure you recall the q45 caliper on millennia rotor bbk for 4th gens, same problem/concept.
Any idea on how you want me to measure the 18zs?
Like maybe draw some lines in paint or sumfin?

After much research, I decided to go with 13" 2003 Mustang Cobra rotors for the rear. You bought the Hawk rotors for 2003 Mustang Cobra for your front setup. How does this work with your Z32 front setup being that the height of our stock front rotors is 49.2mm, and the height of the Stang rotor is 43.7mm? How does your bracket and/or caliper adjust for the difference?

To be honest, I havent the slightest clue lol. Never really looked into the measurements or geometry involved. All I know is that the “dog bone” adapter brackets allow 30mm Z32 calipers to be used with 13” cobra rotors. The ‘how & why’ is beyond me, never really had a need or any inclination to figure that stuff out since the dude who made the brackets already did. Ill see if I can dig anything up about it though.
Got the cabinet LED's wired up and a dust collection system set up. Lots of soldering for those LED's. Tedious work! Nice and bright though. Got the oven breaker wired up and ready to go as well. I also did a few other mods to the cabinet to improve blast performance. I am now setup to blast and powdercoat anything that will fit in a regular kitchen range. No more sending **** to the machinist for this type of work.
Had an issue with ECStuning and their "Complete" gasket set for the caliper rebuilds but finally found a source for all 12 pressure seals (Could not find OEM Brembo seals, settled with Centric) at $100 shipped. Dumb. So dust boots and piston seals for both calipers = $185. Glad I'll only be doing this once.
I have done 4 and 6 piston sets for the 4th gen using Wilwood calipers with 13 and 14 inch rotor. They are smaller in physical size and more cost effective.
When I have some time I will be starting a new set with the below. Definitely not cost effective but I basically got them for free.
Please don’t take offense here. Just wanted to share.
Very cool, Ferhan! I think those calipers are 19Z?
I'd like to see your rotors and 4 and 6 piston calipers on your 4th gen. Got any pics of front and rear? Also, what did you do for brackets? Fastbrake kits?
The calipers are off a 2016 Panamera GTS. I won't have access to a Maxima for a few weeks so, I will just try to clean them up and possibly paint them. Work of measurements for the bracket.
I have some pictures of the 4 pistons. Not sure if have any of the 6 piston. Plan was to make the kits and sell them here but things changed after my Maxima at the time got totalled. I made my own bracket for each kit.
I started on a rear upgrade but did not finish as the car was gone. Still have everything, so once I have a Maxima in hand I can get go on them again.
Below are all pictures for the 4 piston caliper kit. Test fitting Testing to see if 16" wheels work. Yes! Powdercoated Powdercoated Driver side Passenger Side Top front Bottom front Top back Bottom back
Very cool! I'm interested in how you designed and built your brackets. Did you make them yourself? Have them machined? I got lucky and was able to use a bracket that was already produced for the Z33 platform that happened to be compatible with the 5th gen. I'm on my own for rear brackets though. My plan is to measure and send off drawings to a machinist I know in Ohio. I'll probably go with 4140 steel, not sure I have the guts to go with aluminum.
I had brackets made for me locally with my specifications. They are made of steel as well. I will try to dig up what I have later today. Have to get the baby down for a nap now.
The brackets were laser cut. I only had a chance to powdercoat the ones for the 13" kit. Ended up using high temperature paint for the 14" kit and the 12.33" ish rear kit using the stock caliper. Plan was to switch over to Wilwood for the rear as well. The fronts did end up needing about 1.5 mm spacer to center the caliper over the rotor. Pictures of brackets below.

Very cool. I've got a stock rear and the Caddy caliper on my desk right now. Taking measurements. I will have to remove the splash shields from the rear axle to run the 13" Cobra rotors, but that's fine. I just wish I had a spare axle laying around to do the work instead of needing to take measurements from my daily driver. My rear wheel bearings were brand new around 10k mi ago, so I hope they don't have any issues sliding off to remove the splash shield, I'll reuse them. I may just order new rear wheel bearings anyway.
Speaking of Mustang rotors, the pair I ordered from LMR arrived today. One of them is fine, the other I'm sending back for damage. Small chip on inside of outer edge and small dimple on the sweeping surface on the outer edge. Rotors are heavy. Either figure out how to ship them, or expect returns.
I just ordered tires also. SS brake lines and banjo bolts arrived a couple weeks ago. I am literally about two weeks away from having this 4 new wheels, tires, front and rear bbk project finished.
I decided against a proportioning valve. Despite all components being much larger, their size increased linearly with their respective stock components, so in essence, nothing has changed in the bias department.
Two other options for the dust shield without removing the bearing.
1. Cut is off completely
2. Cut off the outer lip that curls over the rotor and you still have a partial shield
Oh and yes, Cobra fronts in the rear. They just made more sense. 1" less diameter vs using the same 2 piece 370Z front rotors, and 29.97mm thick vs 32mm, which actually fit inside the Caddy caliper with about 1.5mm clearance between rotor and pad surfaces with compressed pistons. I could have squeezed the 32mm thick rotor in there but I would have had to cant the caliper slightly to get the smaller pads to contact the entire sweeping area. Not that it would have been a problem, but it just won't be necessary with the Cobra rotor. Bias was the next determining factor.
Hubcentric rings will need to be made to go from 68.1mm to the Cobra's 71.1mm hub ID, but I have an order in for those too.
A bit more unsprung weight in the rear obviously, but I don't care. And it's actually quite negligible. I have all the weights for the new stuff going on, I just need to weigh a stock tire and wheel in order to do full comparisons. I'll add that to my list of **** to do.
I did a lot of work to the dust shields and a bunch of other suspension parts. You can see it all in another thread I started last year. I can't remember the title. I'm not going to ruin any parts in the process of installing the new stuff. I may not like the way the car looks with the new wheels and want to put it all back to stock someday. I really like the stock SE wheels.
I am currently work on something a little different but with the same attention to details.
Engine and transmission mounts done. Engine and transmission mounts done. Steam cleaning the chassis and sealing with Zero Rust and bed liner. Steam cleaning the wheel wells and sealing with Zero Rust and bed liner. Installing coilovers.
Just kidding. Thanks! I was just curious if/how much larger they were. They seem to be the same size in width, I won't know 17Z length until I get home and measure mine.
Making progress, albeit slowly. I ordered the wrong burr and the aluminum keeps clogging it. Pretty amateur mistake but I'm not all there these days. I have a single cut/rough cut burr set on the way from amazon to hog out the rest and get the other caliper relief finished in less than the 6 hours it took me to get this far on this one, with most of that time spent digging and chipping out alunimen from the burr!
I'll be honest, and my dad gave me **** about it, but I totally spaced using any kind of cutting oil on the burr. I've always used cutting oil when working with steel and always spray down my files with WD40 when working with aluminum but forgot about the cutting oil. Like I said, not all there these days.
The rough cut bits showed up today though, so along with cutting oil that will no longer be an issue.
