Just a quick question - are slotted rotors worth having?

I have slotted rotors at the moment, but I am replacing my front brakes with R33 GTSt brakes

I can get new standard rotors for around $100ea, or slotted DBA 4000 for $260ea

Either way I will be using Racebrake RB74 pads, which I am told, Racebrakes don't reccomend using them with slotted rotors?

Cheers, Chris

I always use slotted rotors, they clean up the pads, stop the little balls from rolling around under the pads and reducing the CoF. I have yet to find a set of drilled rotors that can handle the punishment though.:D

Was it Race Brakes that told you about the RB74s...cause it goes against what they did to my brakes, bigger slotted rotors with RB74s...and they have never skipped a beat:)  

About to give Comp 9s a run to see how they compare,

I am going from what a mate was told, as he got some pads off them, but from memory they said that they will work just as well with normal rotors, but I think I will go slotted anyhow, I will chase up a few prices on the DBA 4000's, if anyone knows of/or can get me them at a good price, please let me know :D

i used either Winmax Sport pads or Endless NA-R pads depending on what tyres i was on, on std R32 GT-R discs with R32 GT-R calipers. Then I added Endless/ZEAL Straight6 slotted rotors to my brake setup. There was a marked improvement in pedal feel, stopping distance and also resistance to fade when i added the slotted brake discs, especially on trackdays. would definitely recommend slotted discs to an enthusiast.

Although the RBA slotted rotors are a lot cheaper, with my full set of slotted fronts and plain rears coming in at $560. I use the RB74's and they are a good pad on the track with no fade yet with the backing shims removed and MOTUL DOT5.1 fluid. They are down to about 3mm now and are in need of replacement as they are getting very hard to control easily (not much pressure form slowing to locking).

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
