R34 Gt-t Brake Upgrade

Recently upgraded the brakes on my GT-T. Just thought I should mention especially the pads I'm using, which thus far perform well and came in significantly cheaper than some other options I was looking at (i.e. Endless).

They're made by QFM (Queensland Friction Materials), a company I'd never heard of but apparently those in the know reckon they're pretty damn good. I'm using the A.1.RM compound, which is not their most aggressive compound but perfect for street/trackday use. Temp range is apparently 0-700 and coefficient of friction is comparable to the Endless pads with a similar range (CCX, etc.).

The best part is they came in at less than $300 for a set, front and rear. Thus far they perform well, very good from cold with a better pedal feel than the previous Endless pads I've tried (EuroX and NA-R). Not noisy at all either. Can't really comment on dust 'cos my wheels are filthy at the moment... Looking forward to giving them a nice workout at QR in November (thanks MountainRunner).

Otherwise I've gone down the route many here probably have, which is DBA 4000 slotted rotors on the front (RDA don't make 310mm front rotors for the R34 GT-T), RDA slotteds on the rear, braided lines and Motul RBF 600 fluid. Feels pretty damn good so far.

Anyone else here have any experience with the QFM pads?

Just cleaned the car today (it was pouring rain so I just squirted some detergent on and went crazy with the sponge!) so I'll keep you guys posted on the dust.

These things pull up so well.... won't be able to comment on how they feel after 5 hot laps until November though. :laugh:

Even if I only get 12 months out of them, at ~$250 for the set WHO CARES????

Initial bite VERY good. I have to re-adjust my reflex in traffic, sometimes getting more stoppage than I intended, though that could also be having the fluid bled properly. Pedal feel is excellent for street.

My previous pads were Bendix Heavy Dutys and the QFM's initial bite is better than these and WAY better than my old Endless EuroX pads. The Endless were awesome once they had some heat into them though, but the QFMs are comparable definitely - tried a couple of big stops on a quiet road last night.

I won't give a final word til I've put them through their paces at QR though.

I'll post pics of dust after a few days driving.

Update for everyone.

Been driving on these for a week now.

Dust is minimal. Better than my old Bendix Heavy Dutys, similar to old Endless EuroX. Pic attached is after 500km of city driving. The wheels were not sparkling clean to begin with - as you can see the dust is minimal.

Noise - mild "grinding" noise when cold at very low speeds and pedal pressures. Otherwise no taxi-like squeal. Sometimes a bit of "groaning" as you're coming to a stop down thru 60kmh but this may be due to the rotors.

Pedal feel is very good. Certainly the best I've experienced in my current car. Much easier to modulate the brakes and pedal effort is less, though it would be hard to say how much of this is due to the pads and how much is due to getting the fluid bled. My feeling is that I probably had a little air in the system before.

Performance is good from cold, MUCH better than my previous Endless which definitely had a need to get some heat into them (one hard stop was enough) to work well. I haven't given these a massive thrashing on the road because I don't drive like that on the road as a rule, but with heat they only improve. Certainly haven't got them to fade, which was very easy for me to do with the Bendix HDs.

I'm impressed so far, but I won't be that impressed if the pedal goes long after a lap at QR...

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      Yuck. But it's kinda the same principle, moving timing around to make car run bad but sound good.... I went for a more spirited tuning drive to iron out a few things. Car no longer stalls, and it loved to dip RPM low when you clutch in. After tuning this (and the 4-5 tables that HPTuners/LS1 OEM ECU wants for idle air correction) it's now behaving somewhat normal. All expected because there's a new TB, new Intake manifold and that new TB which is 102mm vs 78... has an entirely different IAC passage which is smaller because ????? Unfortunately at this point I went to make further fine tuning changes to avoid it flaring up, you know... _tuning_ the HPTuners dongle died. Well to be more accurate - The USB cable died in a fashion that anyone who has ever charged a phone will recognize. After the app demanding I resync it 50 or so times (which all 'succeeded' but all failed) the device does not want to sync and I've logged a ticket with support to see if it's fixable. US Support said it was a 'storage issue' but after removing the SD card inside it and formatting it/fixing it the issue does persist. Unfortunately usually the fix is "Turn in your old dongle and pay $700 for the upgraded one" it's cheaper because I get some free licence credits I unfortunately don't need. However I'm 10 minutes down the road from HP Tuners AUS/VCM so at least I won't need to post it, and logged a new ticket for support over here. Definitely drives different. My SOTP dyno believes it's probably making 310-320kw instead of the 280 before.  It scrambles for traction a little now whereas it previously different. It drives like a bigger cam car up top even though the cam is smaller, likely due to the cam not being advanced 6 degrees. The timing is deliberately low and the fuel is very rich so who knows if this will improve on the dyno. It may, imperceptably. Also funny is removing the pineapples definitely makes the car squat more and axle tramp less. So this behavior of having more top end, squatting more, and scrabbling for traction more makes me think = more power. But I could have just been sitting on the threshold of that kind of behavior before. Time will tell if my butt dyno is calibrated right. I need the exhaust leaks fixed before dyno tune for obvious AFR related reasons - I repositioned the pipes but I'm not confident it's fully sealed even if it is better. At least the car does drive around while I cannot tweak/tune it for now. And I have aircon again. medium success!

      I need more than help to finish my R33

      Don't use that manifold. Please don't use that manifold. Sunk cost fallacy is not worth the later pain. None of these will be relevant to the change that will come from the different turbo and manifold. As in, the effect of the exhaust will be nil, regardless of what else is changed. And all the cam and fuel system stuff is not changing either way, so has no effect. The turbo and manifold (and to a small extent the wastegate)....big change.

      Just wanted to say thank you for your input   my man (lead mechanic by trade) and I have done a heap of work as you can imagine just to make the hot side work with the dump pipe, stupid massive intake on turbo, trying to get the waste gate on was not fun.  I’m kinda getting to the point where I don’t know if I try and make this work and not throw all this cash and time away or do I scrap the lot and start again? the Apexi I’ve got was tuned for a few slight differences:   Tomei pon cams (mine are stock neo) Turbo smart 38mm external waste gate (mines 45mm replumbed) with stainless screamer pipe  3inch turbo back exhaust with high flow cat Sard 800cc top feed injectors Sard adjustable fuel pressure reg

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.
