hey i have a r32 approx 260rwkw using for hillclimb/sprints and bit of track im thinking of running r33gtr 324mm rotors with caliper spacers, A1RM pads on the front matched with dba4000 slotted rotors and penrite sin race brake fluid the question is what is a good combo for the rear? do i require slotted rotors along with another set of A1RM pads or would hpx's do the job?

cheers

I posted that in june 2009 - after I had given up on the A1RM's - don't buy them if you can't stand extreme noise! - and had swapped to the bendix heavy duty. A week or so ago they wore out, so I got almost 3 years of driving around town with them on which isn't any where near as good as the original ones.

Needed another pad in a hurry, so put the a1m in that where sitting in the shelf. Lasted in 3 days as I'd forgotten how bad they were for noise! I even tried the anti noise spray etc etc, before giving up on them yet again...

While I was down at repco buying something else, I mentioned I was looking at some new pads and the guy said they do repco branded ones for the skyline now, which are super quite with integrated shims. Given I was buying a few other things he did them for $70 (for the front two pairs) so I thought, what the heck, worth trying.

I've been pleasantly surprised - dead quite, reasonably good feel - but remember I'm not doing track (or anything like it!) I'm just driving around town... If you want a straight replacement when the standard ones where out, I don't think it is a bad choice...

ps PM me if you want a pair of not very used front A1RM's for a r34 gtt for a cheap price, as they are never going in again... :-)

I would strongly disagree about the pad noise. I have been driving with A1RMs on the front brakes with my s14 for about 10months. I drive at least 3 times per week, if not daily. I only experience braking squeal rarely when pulling up. Overall, brake squeal isn't as issue with this pad. I will conceed pad dust is a major factor but probably a lot more noticable on white rims. Cold performance is hard to tell since my tyres also have trouble in the cold, so cant really tell. though i suspect having both susceptible to the cold doesn't help.

Unfortunately HPXs don't last on the track, even on the rears. I thought I could get away with them but after two days at Phillip Isand and 3 months of semi-regular daily driving, they are already gone.

Will be switching back to the A1RMs when I have the time to change them. ( Still using A1RMs on the front. )

just tried a set of QFM A1RMs in my r32 gtr for a club day on the weekend, they weren't at all noisy and worked well but they are around 2/3 worn out after just one day? i would of liked to get a couple of days out of a set of pads or am i asking too much?

Pads start wearing that quickly when they get too hot. Use a higher heat rated pad and you will get a few track days out of one set.

I have been using Hawk DTC-60 on front of my GTS-T and HT-10 on the rear for a while now. They wear slowly, never really fade and work from cold but they are designed as a track only pad.. really bad dust, noise etc. You can get them cheap from http://www.hawkpadsdirect.com/ so for the money i think they are hard to beat. Only thing is they are super super aggressive so take some getting used to. Personally I would suggest a pad thats easier to modulate (they will generally say something like "less initial bite") esp if you arent used to really high friction pads.

If you dont mind spending more $$ then some of the project mu or endless track only pads would be my first choice.

dont rule out the QFM comp pads, ie Comp 9 and comp 2 etc. A1RM's on a GTR at symmons is a fairly big ask, especially if its standard weight with standed size rotors etc.

Has anyone tried the new Ferodo DS Uno pads on track? I had them recommended by one of the larger race brake suppliers in the country, and apparently everyone 'raves' about them.

Has anyone used them and are they worth raving about? Any feedback on durability, disc life, modulation, etc.?

Alternative is Pagid RS14 / RS29 for similar price.

Thanks

Jack

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
