Q45 Brake upgrade with Maxima Rotors?

[KA24Power]

Has anyone got experience running maxima rotors with the Q45 calipers, to avoid drilling the 5 luggers down to 4?

I remember reading it in a thread ages ago, but I can't find it anymore.

Has anyone done it? What year maxima rotors do you need?

Any help would be appreciated!

[KA24Power]

Just found the thread, apparently 94-00 altima rotors are the same size, and are already 4x114.3

I'll be stopping by my local parts store tomorrow to see some q45's versus the altima's.

[lofapoo]

Wow, if correct, that is great news! That would make the Q45 brake swap a bolt-on no-drill operation.

[KA24Power]

for sure, if it is I reccomend a sticky, or at least a link in a sticky

i'll check the rotors against each other tomorrow.

[gaehrings13]

Omg I hope its true because it was such a pain to drill those rotors lol.

[KA24Power]

I read it ages ago, and it was just one post so im hoping its true. I dont' want to have to re-drill them and worry about having vibration issues if its done wrong.

[ZiG]

Damn, they'd probably be cheaper, too..

[white90esex]

wow. If thats true then im putting my Q45s on my dayly and putting Z bakes on the other car.

Find this info out fool.

iirc,

b15 sentra rotors also fit the q45.... i remember someone w a thread using a set of slotted rotors that were for a b15, 11in rotors i believe..

i used http://fastbrakes.com/shop/pro...d=746

drilled and slotted 11 in rotors for 150 a PAIR

good quality imho for the money, check it out

[slo240sx]

The Only difference other then the bolt pattern is the the altima rotors are 6mm narrower i just did my brake swap and it worked out great.

[Atomic-S14]

so which is it? maxima/altima/sentra rotor? so if altima rotors are direct bolt on, i would need to score a pair for Q45 calipers (which years though? ) and get the altima rotors and everything should just bolt right on and no drilling right?

[drzsnapj]

on my 1990 pig nose i some Q45 calipers with some 1999 altima se front rotors and they work great its plug and play all you have to do is use the same bracket bolts and change the banjo washers bleed the system and enjoy the awesome stopping power =)>

What's even better is the price of Q45 calipers are coming down in the Infiniti parts for sale.

[nightsleek240coupe]

i was looking into doing the same brake setup but i didn't know if it would work out, but now i know and that is going to be my project this weekend!!!

so true. i got me a set for $55 shipped... to Alaska

and also there is an ebay seller who sells drilled/slotted Q45 rotors, re-drilled for 4x144.3 for a really good price. just need to pick up some pads locally, and going to go ss lines all around and im set

[raven2345]

as stated above, the altima rotors are a bit narrower than the q45 rotors, which puts more stress on the piston in the calipers, making it extend those few extra mm's. from what i remember from the picture i saw, those few extra mm's are almost to the point of the piston being out of the caliper.

in short, altima rotors are kinda sketchy, and max out the calipers.*this is all research, not first hand experience*

[rico05]

I know from first hand experience that B15 rotors don't work. The hat is 1mm too short and the caliper will not bolt up. I just bought Q rotors and had my buddy that works at a machine shop make a jig and use the CNC drill press to make them perfect. He even chamfered the lug holes for me.

I dunno, but I feel much better about running the exact rotor for the caliper that I have. I have been running this setup for about 10 months and I LOVE it. Although heavy braking will lock the front wheels.

Why would you put different rotors than the exact ones meant for the caliper? The last thing I would ever skimp on is my brakes. That's just dumb. And besides, if they were a perfect fit, everyone would know this and people would not be unsure about it.

Btw, thread from the dead.

[KA24Power]

yeah wtf, bump my thread back up from the dead why don't you.

altima rotors work, but as stated they are a little on the narrow side. I'm switching to 300zx brakes next season otherwise I would get some Q rotors and redrill.

so your saying OEM rotors are the only option when switching cailpers?

im not sure id go that far, theres alot of good quality stuff, and even if the walls are a bit thinner, its not like it makes that much of a difference since they have the same area which is what effects stopping, the thinkness would only effect the amount of wear.

correct me if im wrong folks

[White Comet]

its not like a thinner rotor is a safety issue so whatever, but i'll stick with my thicker rotors thank you. it took less then 20 mins to redrill the front rotors, just do it

you are wrong homie...

the thicker the rotor, the higher heat threshold it has. the more heat it can pull from the pads, the better you stop. "wear" is a term used by the cheap to find out how long til the next purchase. its brakes. buy good stuff. aka oem sizing/fitment.

and the other poster is right... by extending the pistons out another 6mm... thats a LOOOOT... it will cause a misalignment of the piston on the seals and cause leaks/failure for sure.

DONT BE GHETTO, 240 OWNERS

its not just the brakes on your car, its the stuff that stops you from running over the kid who runs into the street to get his rogue ball.

dont be cheap, dont be selfish. upgrade accordingly.

buy q45 rotors from a company that will redrill to 4 lug FOR YOU... for what?, $10/rotor... thats a good deal. $20 for the security of knowings its done correctly, professionally, and will fit 100%.

i thought i taught you better, you goof. uuuugh...

totally a safety issue. overextending the piston is a STUPID idea..

[White Comet]

yeah i didnt really think before i posted but its nico, what else is new.

its ok, half of the people considering using poop maxima/altima rotors will just say "mrgreeneyes is a poopoo head and doesnt know what will make MY car safe... its not like he handbuilt his car from a bare unibody to a full car"...

oh wait....

i did...

ah shucks. and i didnt cheap out. and my car stops like a mofo. using q45 brakes. huh...

btw, new brakes coming soon, to a mrgreeneyes' car near you soon... bigger, better, rarer...

This man speakith the truth.

[hbpignosePA]

i stand corrected sir...

i went with fastbrakes rotors... did a bit of research (now i know i dont need drilled/slotted but im satisified with the quality), i dont track my car much so its all

i personally like your stabs of sarcasm and negativity you throw around at people... and ur car is sick

ill probably get some brembo blanks and get them redrilled next time around

thanks guys. cant believe noone said this all yet.. yikes..

and yeah, im very cynical, and i appreciate that you guys can understand the underlying severity/meaning to what i say. these clowns are cheaping out on BRAKES....

[Panther in a Q45a]

made a quick check of infiniti parts for sale section, and found a guy selling front Q45 calipers and rotors for less than the cost of one brembo rotor.
