Using Altima rotor with Q45 caliper - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

SaGang227 · 01-26-2006, 06:33 PM

I did some search on this subject and 98 Altima and Q45 seem to be identical brake rotor except that Q45 has 28mm vs. Altima's 22mm.
That is 3 mm difference on each side of the rotor and I am wondering if this would be safe.
Does anyone know how much caliper pistons extend? Can they reach rotor without pads in?
Give me your opinions.
Thanks.

Eh, search harder next time, because I found this in 5 seconds.

Be sure to read all the way through, because you can't use the altima rotors according to the last page...

Here ya go!

That's the first thing I saw too but they have not tested it.
They are saying it doesn't work because its thinner.
I've read about people that actually tried it so I am confused.
I'm just worried if caliper piston would not reach the rotor when the pad is worn because rotor is thinner.

well... it's not hard to redrill q45 rotors to 4 lug. You can do it yourself with a 5lug rotor (to plot the dots) and a nice drill press.

Did mine in 20 minutes but ended up selling them.
