Can be had for less, that's list price. Who pays list? hahahaa

 

Some brands (Wilwood for example) offer "lighter" calipers than other brands. Not saying that it makes it better/worse, but they do. I'll probably end up with 2 pc rotors in the end.

Won't a larger rotor allow more pad contact area, which should theoretically offer better stopping distances? I know this doesn't exactly apply to all cases, since the 37 with larger rotors stops the same/little less than the 08 sedan sport brakes. I don't necessarily need a 15" rotor, but I would think that a 14" rotor is "reasonable."

 

I know, but still.....I would say I probably don't need anything of that caliber

 

Like I said, weight differences inbetwen brands ins't going to make or break you. When you say "I'll probably end up with 2 pc rotors", that means you aren't serious about weight savings or you're priorities aren't in the right place. Difference inbetween let's say an oem Akebono 14" 1 pc and an aftermarket replacement 2pc is probably close to 8-10lbs each. The difference inbetween 2 different calipers is going to be less than 1 lb. AND the rotor is rotating mass vs non rotating mass of the caliper. Rotating mass is much more critical weight wise.

I'd go oem Akebono w/ aftermarket 2pc front and back. Perhaps not the bling but definately functional, light and probably the cheaper option. Just powder coat them if you want them blingity

 

The oem akebono pricing is a such a sick deal vs aftermarket. Once aftermarket rotors catch up it will be an even better deal.

 

Stoptech. I used their kit on my 04, and it was top notch in all areas (quality, performance, available pads, and customer service/support). I would consider other top brands like Brembo, Endless, and Project Mu, but for the price you can't beat the Stoptech's. I would personally stay away from untested brands (Rotora and pieced together Wilwood kits, etc.). It's just not worth it when you can get a Stoptech kit for the same price....

 

ConceptZ is working on getting 2 pc rotors available.

 

those would look sick on your FX

 

It's cool the 370z can share the parts so the manufacturer would be smart to make the parts needed!

For comparison, a Rotora 380mm rotor and hat weigh 24lbs, that's pretty significant vs the Brembo of the same size. Aluminum vs steel hats will make a big difference, hopefully the Akebono rotors are made with aluminum and it's good aluminum at that.

Brembo Monobloc 6 caliper full assembled weighs in at 11lbs. I can't remember what my Rotora 8s weigh but they are hella heavier than that.

 

my 6 pot Rotora front calipers weigh 12.98 lbs each

 

Nice! I guess this thread is starting to have some decent info in it. What do the Akebono calipers weigh, and what do the oem rotors weigh for the second gen sport brakes?

 

Front Akebono 1 pc rotor is something like 26-28lbs. But someone posted 30lbs.

For instance, a 11.5" 03 1pc rotor is 15 lbs. The 12.6" oem rotor is 18lbs. Adding 10-13lbs of rotating mass is killer. Although it's not an equal comparison, would you guys like to have wheels that are 10-13 lbs heavier?

IMHO, if the newer sport Gs with 1pc Akebonos swapped out to the 2 pc fronts, I'm sure it would make a difference one could notice.

 

What about the Akebono calipers? Share the knowledge man! lol

 

haha. I never really concerned myself with caliper weight. They are all forged aluminum and are all lighter than the oem cast iron calipers. Plus, they aren't rotating mass.

 

I'll be picking up a set of rear Brembo 4s tomorrow. I'll get the weight of those. http://my350z.com/forum/brakes-and-s...03-07-g-z.html
