Can anyone look up a part number for me??

41001-64U01RE

I have two front calipers, don't know what they are!

Here are a couple pics:



They are going on Ebay as soon as I can determine the fitment. I think they are an Infiniti part number. I also think they bolt up on a S14 240.

Anyone?

Thanks!

I'd call Joe at http://www.infinitipartsusa.com.

Looks like a Q45 with the 64UXX tag line, but I'm not sure.

Just as a side note I finally finished rebuilding my front and rear calipers, new slide pins and seals [$60]. They were primo inside just a little 200 grit sand paper.Finally spent an hour grinding on my LF hub [255k] to get the runout down to where the rotor outer edge was less than 0.0016" [spec 0.0028"] it had gotten to 0.004".

Now if I can just figure a way to stop the warping every 7,000 miles [even with powerstops]..........gotta be the heat and metal masters.........everything is brand new.

Are you saying the metal masters transfer less heat out of the rotor, or that they generate more heat during braking?

I've been fighting this problem for 5 years since Infiniti dropped the - U90 front pad.Remember my sensitivity to rotor vibration is enhanced. Also no one knows for sure if the Metal Masters of yore are the same composition as we buy today. They look the same have the same numbers.

Just the fact that the 17.5 pound 28 mm rotor can only stand so much.

Car: should be obvious enough

*those calipers should be a direct bolt on to the J30 too.

True all 90-96Q and all J30 fronts are the same. The rears are different as the J30 has wider vented rears vs Q 9mm solid rotors.
