Personally if it's coming down to Q45 vx 300ZX is make or break a setup, then one should be looking at Brembo class calipers anyway.

I am running R33 GTS-T (296x30mm/297x18mm).

Well one reason could be the weight difference betweem the Q45 and the Z32 seater.

curb weight:
Z32 ~3300 lbs (2 seater)
Z32 ~3550 lbs (2+2)
Q45 ~4034 lbs

I'm gonna have a set of front Q45 brakes for sale soon!

PM ME!

!Zar! · 10-17-2007, 09:25 AM

q45 brakes stop your car better, clear wheels easier and aren't as expensive nor require all that bs to put on.

But as said before, z32's look sick.

You choose.

***CrimsonRockett*** · 10-17-2007, 10:14 AM

I think i'm good.

Skullavera · 10-17-2007, 10:24 AM

Haha! Slap those mofos on so you dont hump my car!

good to see you got everything in.

***CrimsonRockett*** · 10-17-2007, 10:26 AM

I need rotors!

You know you loved it from the back.

jrocslider · 10-17-2007, 10:48 AM

Dousan is right... people get Z's cause they look better. not everybody but the majority.

i have sum 30mm with ss lines sittin in my garage and havent put them on because i want better wheels and dont know if in the end they will clear so i've been contemplating on selling them and just gettin Q45's

in my defense, and lots of other people's...

the looks was a factor, but not the main reason i got them. weight, caliper stiffness, and pedal feel were bigger factors. it's also a reason i didn't go with a flashier, better big brake kit (aside from overkill). i love that it has the raised nissan on the caliper, but i'm a nerd like that.

q45 brakes look like the stock brakes so if u want to cheat in autox and escape any classification rules they are the way to go

!Zar! · 10-17-2007, 01:57 PM

Hmm.

q45 front, z32 rear?

I second the notion. Can I get a Yay or Nay?

e1_griego · 10-17-2007, 05:39 PM

I was under the impression (from Asad's techno-post) that the q45 brakes gave a very high front bias.....is this true? Is it noticeable?

OptionZero · 10-18-2007, 10:26 AM

did we ever come up with an explanation why s14/s14 silvias got 3Z 30mm fronts but stock s14 rears?

Was it:
1. the s-chassis has different weight distribution from a Z

or

2. the BMC is different and corrects the problem

or

3. other

olah.inc · 10-18-2007, 11:04 AM

you have a pic of the q45 caliper?

There ya go. After $25 in rebuilt parts, they're good as new. With a total of $110 spent on calipers, rotors, and seals; the value can't be beat. These pics don't include the slide part (torque member)

OptionZero · 10-18-2007, 11:12 AM

google is your friend, shoot

olah.inc · 10-18-2007, 11:14 AM

didnt found some, just pics of the rear and backside of the front

alkemyst · 10-18-2007, 11:24 AM

In regards to the Silvia getting only fronts.

For one most of the braking is done by the front, it also allowed for no redesign in the rear which would require more extensive setup on the assembly line.

Even the stock 240sx brakes are decent enough for many with just a track pad.

driftskeetka24e · 01-15-2008, 02:22 PM

so running q45s up front and upgrading the bmc is not necesary? or if you were to run q45s up front and stock rears which size bmc would you run the 15/16, 1, 17/16 or just keep it (7/8) stock?

its actually best to keep the stock master cylinder when upgrading the q45 front with stock rears. The brake pedal feel is pretty incredible. I have had both the q45 and 300zx/skyline calipers and I cant tell much difference. It may be different on the track though.

you keep the stock bmc. it is what i run and have no problems. although the aluminum caliper looks cool when parked, it would be pretty hrd to see it when i drift by you.

IGSDann · 01-15-2008, 05:55 PM

+1 For Q45's. I just set my car up with them, rebuilt the calipers, got some brembo blanks, hawk hps and speed bleeders. And it made for a very quick and easy upgrade with great stopping power.

hijack3d · 01-15-2008, 06:33 PM

Running Q45's right now in the fronts w/ dimpled/slotted rotors, and Hawk pads. The rears are simply stock w/ Hawk pads. The only complaint was experiencing rear brake fade after a little over two hours at the Balcony (and this happened only once when my diff blew, and I was just yanking the ebrake)... But that doesn't really answer your question. It only tells you that I thought the Q45s were the better option for my slightly-tracked stock S13.

I guess you really have to look at what you're going to be doing with your car. If you're just daily driving without lots of power, why spend the extra cash? It's not too much more expensive, I know.. but at least you wouldn't have to worry about wheels clearing your calipers.

smelly240 · 01-15-2008, 06:35 PM

i remember this thread - so everyone knows porterfield, hawk, endless all make pads for q45/j30 brakes

and yes the feel is good with stock bmc and q front and stock rear.

its not like the z front - where u get the brakes lockin up all the time.

ill never go back to z brakes - wilwoods yes... that i'd like.

apexhumper · 01-15-2008, 07:46 PM

Good stuff.

Just a quick question, for street use I just have my stock brakes but every once in a while when someone that didnt pay attention because of; eating in the car/talking on the phone/applying makeup etc etc causes me to have to stand on my brakes there are times that it seems my stocks didnt get the job done quite as quick as they could've and I cant help but think that this close call wasnt necessary if I could just upgrade my brake set up properly.

So for the best stopping power in SoCal street use what do you guys recommend? (including pads, fluids, lines...anything that might help) Dont mean to jack a thread or sound like I'm repeating the question, but once again, no track use, just street.

IMO

#1 Q45/J30 all around

or

#2 Z33 Front rotors (ofcourse you need adapter bracket with Z32 calipers) and Z32 rear

Either if these two setup will knock the socks off of a stock s chassis brake setup and not be dangerous and have the correct front to rear brake torque/bias to not let you get into trouble like the Z32 setup all around will.

But your results will vary on Z32's all around based on weather you run a staggered wheel setup (have more grip in the rear) or have more weight in the rear of yoru car, somehting that keep the rear planted to teh ground like a 200lb sand bag will help a bit as well as a full tank of gas at all times...lol.

Why would Z32's all around "get you in trouble" ?
