Hey,

Has anyone purchased these brand rotors? If so what was the part number of the front slotted rotors (For the R32gtst) and how much did it set you back?

Any general comments about this brand? A lot of items are half the price of DBA's and I have only heard good things about it (Also its Aussie company).

RDA909 is the base part number. From memory, I think you might add an SL for slotted. Anyway the shop you order them from should know what you are talking about if you say you want RDA909 slotted.

Should be somewhere around $170-$200 for the pair.

I was talking to a mate who has a set of slotted rotors on the front of his R32. He mentioned he had a set of DBA's or something where the slots were straight, he said when jumping on the brakes really hard at the end of Mallala straight.you could feel the slots pulsate/vibrate a tad.

He ended up getting a set of std rotors and had them slotted with curved slots, now he has nice smooth braking.

For the price of RDA's.. straight slots.. I care less. :laugh:

Bit of a wank factor every time you feel the 'slots' lol. :)

I use RDA slotted on my gts25t racecar and prefer them over DBA as the slots go all the way through without the afterthought reverse slot DBA have.

Never had a problem with vibration or pulsations using RB74 pads and braided lines with a massive stopper so I expect it would be a rotor with an area of cementite transformation due to a hard braking moment and then not getting off the brakes while stopped. I feel the feedback from RE55S semis more than anything anyway.

RDA have a new option with curved slots and dimples (not drilled through) for GTR so may be available for GTSt

The current range of RDA/EBC Brakes is known as the "turbo groove" which uses curved slots and a dimple design rather than cross drilling. According to EBC using the dimple eliminates tiny hairline cracks that can form with cross drilled brakes.

Andyn,

I got myself a complete set some months ago for my R32 GTR. I have had no problem with them although i am running Project U level 900 pads now so i know they will be harder on the disc than the Bendix ultima pads iwas running but they could just not stand up to 3 track days :thanks:

I got mine from ABS and i paid 710$ for the complete set for the GTR.

I used these on my 32 with EBC Greensuff pads and was VERY impressed. Makes for an awesome street setup and works great for the occasional weekend warrior ( but no good for the hard core track junkie ). I would have stuck with them if I knew where I could get more ( I now know ). Some people complain that they wear out too fast but IMO, it wasn't that bad and the stopping power and lack of brake dust was worth the wear rate.

:P

      R32 update from 1990's spec.

      By djr81 · Posted

      New CAS just turned up from NZ Wiring. Looks like a nice bit of gear.  So, yeah. Triggered, bro. Realised I may as well do the cam belt while mucking about with it so will order one of them.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.
