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

    • The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG is has not responded to my emails so far after purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.  
    • There's a good German place in Brisbane if youre up for the drive 😛
    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋
