Endless Brake Callipers - Info Wanted
djr81 replied to djr81's topic in Suspension, braking, tyres and drivetrain
Yes they do. For all of them. Which is why I asked the question. I don't want to have to be locked into the Endless pad range because of the calliper. -

Yes but according to the nice people from Ferodo the friction coefficient is stable across a large temperature range. That is one of the reasons why I like them. -

The ones in the photo are just some random stuff from Yahoo auctions - they appear to be a 6 pot calliper on a 324 rotor. Not what I was after, but they would be a good thing none the less....so don't let me stop you. -
Endless Brake Callipers - Info Wanted
djr81 replied to djr81's topic in Suspension, braking, tyres and drivetrain
Well I have heard good things, but.....I have two issues (OK, I have more issues htan the Readers Digest, but I digress). 1. The quoted friction coefficients are low - in the 0.35 - 0.4 range. Compared with the 0.5 I have on the DS2500's it looks horrible & low. 2. I need the pads to be useable on the road (ie work from cold & not squeel much) but also not run out of friction coefficient on the track when they get hot. I sent an enquiry to Centrax, but they ignored it. Guess I will have to ring them aswell. -
Endless Brake Callipers - Info Wanted
djr81 replied to djr81's topic in Suspension, braking, tyres and drivetrain
Yes they are good value for money. But my principal concern is getting some good pads to go with them. I finally found some Brembo rears & there was a set of Endless pads in them. They look for all the world to be nasty old school metallic type pads. the 6 pot calliper looks to have a 152mm long pad. But that is just scaling the photo, so I don't know. -
So its different from a normal Friday/Saturday night how? Oh, sun burn. Right you are.
-
Some questions about the Endless brake callipers: 1. Is any one out there running them - if so do you have any comments? 2. Are any of the Endless range of brake pads any good? More particularly I would like to ask for their "inch up" 343x32 rotor + 6 pot calliper does anyone know: 1. What pad size is it? 2. Can you get other than Endless pads - particularly the Ferodo DS2500 or equivalent? 3. How much piston area do the callipers have? It is too bloody hard finding information on callipers most days.

I would be disgusted but then again I am in no way surprised. http://www.itv-f1.com/News_Article.aspx?PO_ID=41405

You are dead right. It had more than a bit. But then again the car will understeer when I try & be a hero and attempt to carry too much speed across the apex - so it was as much my fault as the car. It needs a new rear diff to stop the inside rear from bagging up, particularly on the left/right transition going up & over the hill. Mid 66's (my best effort) & 65's are a different world, but worth aspiring to none the less.

If you are ever sufficiently bored check out the history of the John Wyer's Mirage cars at Le Mans. They used to run DFV's in the 24 hour race & the vibrations just tore everything apart. I would hate to think what happens in a road car.
-
Maybe, but my argument stands.
-
That is because they have flat plane cranks. Which no one in their right mind would ever put in a production car. Although Lotus did it once - which kind of proves my point really.
-
1. Yes. 2. No. That was two questions by the way.
-
Not sure why the track was so slow. It had little grip & strangely absolutely no traction for anyone. I talked to Steve about his brakes on Sunday so I understand what he has got. Unfortunately I need to buy me some new tyres first. Atleast our bullsh!t carry on on the pit exit gave John Hurney a laugh. Something you don't see enough of. Yes Mike is a good steerer. As are quite a number of the blokes doing the speedeventseries. The competition is pretty fierce. Drop half a second & you are in the midfield.....

No. Although I do know they aren't cheap. Try the Nissan badge (says Nissan) for just under $100. There is a thread for part numbers etc & if you ask nicely I am sure someone will dig up the pricing.

Are You Cracking Dba Rotors?
djr81 replied to Roy's topic in Suspension, braking, tyres and drivetrain
Sorry to bring this up again, but from where did you order them? I can't find anyone who either lists them or is willing to admit they can supply them... -
Good question. The only difference between them is piston sizes - with the F50 being larger than the F40. Pad size is considerably larger than the Brembos Nissan fitted to the GT-R's. I have been tempted to try & find some F40's but they are hard to come by. Biot in Japan no longer appears to list them, instead replacing them with something called a Modena (F360?) calliper. Not sure how the two compare. I am tempted to suggest maybe finding a second hand monobloc Brembo instead. Don't know from where although there are a couple of GT-R's running them locally. I don't think I would ever stump up the requisite to buy new Brembo product locally as the pricing is pretty fearsome. If I wanted to spend that kind of coin I would probably go for some AP stuff. Who do you deal with locally - Perth Brakes?
-
Get them new from Nissan. They come with an adhesive sticker on the back & putting them on is a breeze. If you get second hand ones you have to arse about getting them to stay on & it is sometimes hard not to make a mess.
-
Ah, welcome to a world of pain. And expense. Do I have an answer, well in short no. The biggest rotor you will reasonably jam in under a 17" rim is 13.5" - 343 in metric speak. But that is dependent on what sort of rim you have. Some will fit, some won't. If it is a Volk/Rays/Nismo/SSR/Enkei you should be ok. Otherwise, probably not. If you can't fit anything larger than 324 probably just go with Brembos from a 33 R. Do the braided line, good pads, fluid, rotors & remove the stone guards. That will get you 1.1 gees of brakes which is good enough to lock wheels.
-
Well yes & no. My lap time isn't special. It was mostly done on hp & brakes. Certainly not traction or grip. Hopefully fresh rubber will bring a gain. I had bulk wheel spin on every corner exit. Not productive in any sense. Brakes: Standard R32 callipers. DBA rear rotors (till they crack, again). Now project Mu front rotors. Ferodo DS2500 pads & motul rbf600 fluid. But I need an upgrade.
-
The thing that sh!ts me to tears is that another half a second would be about, oh 5th. Coulda, woulda, shoulda. But doable, maybe. Unfortunately by the time I find half a second so will everyone else. I was cleaning up in the shed last night thinking that flushing $50 notes down the dunny may be a cheaper hobby. See the photos for dead brake rotors collection. Anyway, wait till they get a load of this....
-
Well 80 psi is dead or atleast in cardiac arrest. A good motor should give you a figure or 150psi or better.
-
Well my ten cents worth. 1: 19" rims are a waste of time on an R32 GT-R. 2: The heavier the rim the worse the ride/handling/grip/tyre wear of your car will be. 3: The larger the rim the heavier it will be. 4: The larger the rim the more expensive it will be - same goes for tyres. Unless you buy cheap rubbish in which case you will be punished with a heavy rim. 5: The right offset for an R32 rim is +22. 6: The right rim width is 9 inches or maybe 9.5 if you want to push it. 7. Tyre size should be 245 or 265 in 18's. Any larger than that & you get clearance issues at the rear. You may get them anyway if you lower the thing to any degree. 8: There are plenty of options if you are prepared to either wait (Ex Japan) or find something second hand. 9: GT-R's are too nice a car to put bad rims on. My recommendation? 18*9 rim in a +22 offset with either 245/40/18 tyre or a 265/35/18 tyre.
-
Certainly is. It is for sale, too.

Went ok. I just need some new rubber as the old stuff had been heat cycled too many times and had lots its edge. That & a new diff would do wonders. It is all good fun in any case & its not for sheep stations. This should give everyone an idea of the sorts of cars that turn up - basically anything you can think of!
