R31 rear brake conversion

[luvdemzeds]

hi,could anybody tell me which brake rotor is used for a R31 rear disc conversion,on a 26o2+2?

There seems to be a few that have been mentioned,but nothing to say which is the best rotor to use,with the least amount of engineering reqd.

Thanks in advance.

The standard R31 Skyline Rotor is a bolt on with no modifications required.

Get a slotted set too

just as a matter of interest. What sort of performance increase would you expect from a slotted disc compared to the standard disc of the same dimensions?

On the road - probably SFA.

On the track, it just helps to de-gas the pad face to help maintain pad consistency.

Thanks Lurch,much appreciated.

And only really worth doing on the front if at all.

 

There isn't much difference in performance between slotted or standard for Zeds. The biggest problem we can have id to overbrake the car.

 

I was looking at getting new calipers to fix the brake problem I have, but at the moment it looks like I can get away with rebuilding my calipers, saves me some big dollars and fabrication work.

 

The new calipers were going to be Wilwood Superlites, a lot bigger than the Dynalites I currently run and will be getting repaired. The rotors with the bigger caliper were going to be a 298mm Alsa rotor, that was vented only. The current rotors I use are standard TP Magna rotors, about 270mm in diameter and depending on cost I usually get standard vented, though currently trying slotted to see what difference it will make to overall performance.

 

With the slotted rotors and my usual carbon metallic pad they make no real difference in performance or wear.

 

Having said that the car weighs 960kg, so is relatively light compared to other categories where slotted rotors are a must, along with the biggest caliper and most number of pistons you can afford.

I found slotting the rotors made a huge difference on my zed . the rotors have been on the car for yonks and only starting to look like they might need grinding, just gave the brakes more pedal feel and bite

Ive looked and searched everywhere but cant find the post on the pics and mods required for the R31 caliper mounting bracket. Can anyone help, Ive seen them somewhere but for the life of me cant find them now?

 

Thanks.

There is some here:

That's the one!!! Any wonder I couldn't find it.

 

+1 for the sticky Lurch or Dimitri.

If someone wants the coversion done  & can get some rear struts, R31 calipers, brackets & rotors to me, i'll do the conversion for FREE.

I'll then post up tutourial on how to do it.

What a legend.

People are going to hate me but that conversion is sooo last century. It is convenient and easy to service but for braking performance no better than ye olde drumses. By current standards something like a 300mm minimum diameter rotor would be appropriate, we are driving performance cars after all

Richard,

I seem to remember you saying, I didn't bother using slotted rotors because you really don't need them on the rear of an S30.

Now your saying you need bigger discs?

 

P.S. Just giving you a hard time mate, I couldn't agree with you more, the bigger the better, if there is too much brakes then you just push you foot less.

There do seem to be a lot of options for rear (and front I guess) conversions - are there any resources anywhere that compare the choices, pros and cons etc?

300mm on the rear    I did this mod years ago and still ran standard front brakes, it was a big improvement over the drums. Only problem it's a pain in the ring to change pads, winding the pistons in sucks and unless you mount them at 12o'clock they need to be removed to bleed.

 

Thinking of changing my pads makes me wana cry  :'( hehe
