I checked out some 6 pot Porka calipers today. On a Skyline the pistons are going to be around the wron way.  

...

What about the UAS setup then Roy?

[Roy]

Yeh, i dont htink the piston orientation is correct...i want to ring and check with John when i get a minute.

Harrop make setups for whatever you want, they are radial moutn calipers so you can do just about whatever you want with them...thig is are they worth the $4,000-5000?

[Beer Baron]

that will be a shame if the porsche ones can't be used as they are only around $1600 a set BRAND NEW! very cheap for such awesome calipers.

EDIT: just realised i'm about the 5th person to mention the price of the pork calipers. just ignore me.

And another thing you should check before buying these sorts of calipers is the availability of pads. You may find that you have to run a pad like DS3000s which are not only noisy, but quite aggressive on the rotor.

Good one Roy. Sounds like you've got this issue by the scruff of the neck. Please let us know what you find out, this thread is one of the good ones where we get to the bottom of it.

I've got ds3000's currently in 33 GTR brembo's and find that if you use them a bit on the street they quieten down alot once you get some street wear on them. Go do a few high speed stops (100-0) and then they clean themselves back up again and are there usual squeeky selves

How do you find rotor wear? Im noticing going from the old RB74s to Comp 9s that i have noticeably more wear on the rotors after only about 1,500 road kms and 4 track days, and Comp 9s arent as racey as DS3000s:(

Guys, I've just been having a chat to Hyper-Tech in Nunawading - they make the CSC brake kits...

If you're interested they have a special on 4 piston CSC brake kits for GTR with 355 x 32mm two piece discs for $2200.

The engineer is an ex-Harrop lead developer. I am waiting for some more info on them, so will post something up when I hear.

from memory Jason (gtrjason) has a CSC kit of some sort on his GTR. having been in that car I can say it stops pretty bloody well.

Some more - Harrop GTR kits:

See how the caliper doesnt have the bleed lines and recirc lines connected. I htink thats so you can use it on either the front or rear of the rotor and still ensure the smaller pitons leads and larger pistons trails.

So i still suspect you may be able to swap them around on the GT3 calipers.

If he can also do a CSC 4 pot , 343mm rotor, then id be VERY INTERESTED:)

Almost guaranteed that he can... I have some PDF flyers too (too large to attach, so I've emailed it to your work mate)...

May be cheaper too

Talk to Arnold at Hyper-Tech

I would like to try them out, but need some rims first...

Also, I don't see how it would make a difference if you swap the bleed lines for the calliper. All it does is to connect the L&R of the calliper to show equal pressure for the pistons??

It's nothing flash, but once you get a bit of crap built up it seems to slow the wear rate down. I am using projct Mu 2 peice rotor's though so that could also be a factor.
