All Australian ST185's got a rear rotor of (DBA744):
Vent: Solid
Diameter: 288
Height: 60
Thickness: 10

JDM ST185's had a much smaller rear rotor.

hmmm, then it may not be much of an improvement for the 185 guys except that you get a slightly bigger piston and vented rotor. 205 is probably the better option for those whose residing country sold them. For the US, rear still exceed $300 with used rotors :(

Next time im on a track ill try to remember to measure rear rotor temperatures.
Our local track (Mallala) is the hardest circuit on brakes in Australia.

I overheat my front pads/rotors (std 185, using DS2500 pads) in 1-2 fast laps :(

ATTENTION

Alright so I sold the last kit and I'm currently getting quotes for making kits for the 185 guys. I however do not have a 185 and my access to one is somewhat "challenging"? Anyways, I went to the junkyard on Friday in search for a 184 LCA and upright and forgot the necessary tools to pull an axle because I'm an idiot. I have machine shops hounding me for models so this is where I need your guys help.

What clearance are you looking for? If any of you have a STi rotor laying around and some washers, can you test fit and see how much space is required to space the rotor out? I would like some pictures also. I had currently estimated that it needed around .125" of offset. I will be waterjetting a steel plate that sit behind the rotor and have the steel concentric ring tacked on the inside. So this will slip on over your hub/wheel studs before installation of the rotor. The bracket will then be redesigned for the larger .125" step.

Ahh, no worries. Did your buddy get his kit yet? I haven't heard back from him since I shipped it.

I'd push it out a bit more than an 1/8" to have adequate clearance on an STi rotor.

What are you thinking? How much material did you shave off your ball joint?

I've taken a fair bit off already and it still rubs, I'll try to measure once I can get it to stop rubbing.

So im finally starting to look at doing this upgrade :twisted:

328mm WRX STI rotors on the ST185... maybe i have smaller ball joints or something??
I have plenty of room.

And how much room is there under compression? With my rotors, there is around ~1.5mm space between ball joint and rotor.

Lol, I didn't think about that, thanks :twisted:
I have some other parts I need to have water cut, so was going to have some behind rotor spacers made up anyway.

Mine were making contact under compression at nearly full lock, so I'd check that as well.
