first of all, I'm am talking to this dude on ebay about the calipers he is selling and this is the email he sent me:

whats is he talking about???

second, if I get the drilled and slotted 300zx rotors, would those be able to be milled down the 3mm, or do I have to get plain OEM ones?

third, the instructions on maximadriver say you need calipers from 92-96 300zx. Are those the only ones that will work, or can I use any calipers as long as I get the appropriate rotors?

*edit*

which calipers are better to get steel or aluminum?

 

When he is talking about the rotor gap he is elaborating on the fact that there were 2 seperate width rotors offered for 300ZX's during the years, a 26mm and a 30mm. They are the same diameter, but the width is different. Only benefits the wider rotor gives you is better heat dissapation (sp?) assuming you have a caliper with a 35mm gap.

I'm not sure about the grinding down of drilled rotors. I assume it would be possible as long as all holes are complete and some aren't half shaved. . . But I could be wrong. I know drilled isn't recommended though as they have a tendancy to crack if not done correctly.

And getting Aluminum calipers are recommended as they are lighter than the others. I think they actually made these calipers out of three types of metals. I know aluminum is harder to find though, so I wish you luck in finding them.

 

I understand that, but in no place that I read about this, has there been mention of 35mm.

hmmm...
cool, i'll go with aluminum then.

Thanks

 

i think oem skyline rotors were 32 or 35 mm


for our application you still have to mill down 3mm so they will fit.



the aluminum ones are lighter, but both iron and aluminum calipers do a good job.

 

one more question. when I get my used calipers in the "as is" condition, is there anything I need to do to make sure they work, or to recondition them before I put them on?

 

I dismantled mine. I checked the pistons and all the seals. The rubber was still very pliable and had no cracks. I just reassembled them and they are good to go.

I know the pistons are like 30$ a piece. Mine just had surface corrosion on them so I reused them.

Caliper rebuild kits for them are like 33$ I think. Has all the seals you need and the clips and such.

 

Read this page, and view all the pics (they have text written in them) and you will understand.

This is quoted from that page
Look at the pics too.

 

Yeah, I read it, and it mentions nothing about the 35mm. The thing that threw me off, is that he lists the 26, and 30 as 30 and 35 respectively. So I was about to get the 30 when I realised that his 30mm means 26.

Sorry for not posting the URL correctly before.

 

yes, you will still be able to mill X-drilled/slotted rotors down by 3mm...I had this done on my brembos when I installed the 300zx brakes on my car
