Rda Vs Dba Slotted Rotors
gslrallysport replied to crazy.mofo's topic in Suspension, braking, tyres and drivetrain
Unfortunately the GTT rotors aren't available from Project Mu in their entry level Pure Plus 6 rotors. To get a PMu rotor for the front of the GTT you need to go up to their SCR rotors, and these are $790 for a pair... -
Thanks mate, just one favor to ask, if you're going to purchase please don't go through ebay. Contact us direct on either 1300 884 836 or email sales at gslrallysport dot com We'll still honor the free shipping as per on ebay. Regards, Greg

Brake Pads Users Ratings Guide
gslrallysport replied to Snowman's topic in Suspension, braking, tyres and drivetrain
Not expecting a semi-track pad to chew through a set of rotors in 30,000k's is being a bit naive... Ask some people how long they're getting out of rotors with a set of Project Mu HC+, I think you'll find 30,000km, from a pad that you could've done light track sprints on, is fairly good. -

Why did you fit A1RM to a car that was going to do 30,000km of daily driving??? The A1RM is a semi-track pad, something you run if you're prepared to accept the fact that rotor wear is a consequence of track type performance. If you weren't going to do any track days, then the HPX (Bendix Ultimate equivalent) would've been the pad to get. 30,000km from a set of track or sprint capable pads is pretty good... Let us know what QFM say when they get back to you! -
G4 Racing Brake Replacement Parts
gslrallysport replied to skylinekid's topic in Suspension, braking, tyres and drivetrain
We've got QFM A1RM (Ferodo DS2500 equivalent) pads on the shelf to suit the G4/D2 8 piston fronts. $179 for the axle set. If you want a dedicated track pad we can do the QFM Comp 9 for $229 for the axle set, or something from the Project Mu range... -
*** Use of A1RM pads in a street-only car! *** We'd like to clear the air on an issue that has been brought to our attention. Just recently we've had a customer query us about rotor wear when using the A1RM in their road car. The customer was running A1RM in his daily, which albeit driven hard, was only used to drive to and from work, and the occasional run over the hills. The customer got 15,000 km from his rotors (which admittedly had already been machined once) and the pads. Where this has caused some unrest is that they were very expensive two piece rotors, and so is up for new rotors at substantial cost, so in light of all this, I feel it is necessary to clear a few issues: - The A1RM is a street/track cross over pad. Even though it is 100% streetable (cold bite is substantial, generally noise and dust are low enough), it is a pad capable of light track work (similar to a Project Mu HC+ or Ferodo DS2500), and thus will had some drawbacks when being used only in a street only driven car. If you're using the A1RM in your road car because you'd like the ultimate in street brakes, be prepared to change rotors sooner than you would with a regular street only pad. - The pad below A1RM, the HPX, is a Bendix Ultimate equivalent in terms of performance, so is more than enough for most hard street driven cars. Because it's also very low dust and rotor wear, we supply them as a direct trade servicing pad to a local QLD Ford dealer for use in Falcon's and turbo Territories that use the C5 PBR caliper. Average pad life on those cars with the HPX is about 45-50k kms with low rotor wear. - A rotor life of 15,000 k's on an already machined pair of rotors (so maybe 20-25,000 k's on new rotors) is fairly good for a pad with the performance of the A1RM. Equivalent pads with the same performance will be no better than this. The A1RM gets a very good wrap because of it's price/performance ratio, and if you take your car to the track to do some light club springs or circuit work, and accept that brakes will wear out quicker using performance items, then it's still the perfect compromise. If you don't do any track work at all, then probably best to stick to the HPX. Personally, I run the A1RM in both my rally car, and road car, and don't have an issue with it in either. Additionally, we're also well aware of road cars that have gotten 25,000-30,000 (about 1 year) and a couple of track days out of rotors clamped by A1RM, so the wear will vary with individual vehicles and applications. Any further questions or dramas please do not hesitate to contact us direct on 1300 884 836. Regards, Greg

I would use QFM HPX over Green Stuff, let alone A1RM, which itself will make Red Stuff look stupid. Also, for those not interested in caliper conversions, we do now have Series 2 Stagea front pads custom made on the shelf ready to go in both compounds. HPX are $119 for the set, A1RM are $179 for the set. My only input to the original question would be to check the wheel bearings, which can have more play when hot...

If you're changing standard Dot 4 before every track day, then that may be enough. Certainly going to a high temp fluid is an advantage, but where fluid looses it's edge, is moisture absorption. 6 month old GP600 may only be as good as brand new Dot 4. It doing that works for you, stick to it. A1RM are a stack higher than TRW. Any normal street pad (TRW included) will be in the 0.35-0.43 ish range... Friction levels are pretty useless because there's no standard test for it. Manufacturers just release figures based on the equipment they use. For example Ferodo DS2500 are rated to 0.50 hot, but the majority of anecdotal feedback from that that have ran them back to back against the A1RM is that the A1RM bites harder when hot... Takes friction figures with a grain of salt. -

TRW GP600 Racing Brake Fluid, $65 for a 1L bottle, and good for 312 degrees dry. Conforms to both Dot 4 and Dot 3 FMVSS No.116. -

No chance. Standard Dot 4 or OEM fluid is good for about 250 degrees dry. To do any sort of track work you need a fluid over the 300 degree mark, like the 600 fluids that are 312 degrees dry.
