Are starion rear dics vented?
Simple yes or no.

Anyone got a set they willing to sell? (pref sydney)
More complicated yes or no.

Ones that I have seen are solid, but I believe DBA and RDA do do a vented version.

The rotors in the pic are around 17mm thick. New ones are 18mm, and min thickness is 16.4mm.

I have heard the same. I have the rear brakes, and will take lots of pics for my build thread if I can source a scorpion diff.

I have been told the same that they do.....with this many people saying it im sure they will.
However the main problem will be the diff centre as always lol.....trying to find a decent setup (ie LSD, detroit) that is relatively cheap is never an easy option.

But are the EVO's a direct bolt in? Do they have same spline count on the driveshafts/axles?

Define cheap Matt. I am looking into a setup right at the moment that is $500ish dollars and gives you a auto locker. drives like a lsd but stronger and lasts heaps longer. It purchased from the US but built and manufactured here (go figure) Trying to get the australian supplier so we dont double handle but it uses your existing centre just replaces the spider gears.

Doesnt sound like any diff ive heard of before. Is it like a Detroit locker or a Full Spool? Detroit acts sort of like an LSD (locks under load from engine) and Full Spool is in replace of spider gears and diff is constantally locked (better version of a welded diff).

More info please, you have me intrigued and very interested.
$500 for a locking/LSD diff centre that fits into a scorpion diff (espeically if its still made now so we can get new parts) is excellent and dirt cheap. I can afford that, and i think a lot of people on here could too.

Pics/website to look at info of this diff?
What brand is it?

Yes it is similar in principle to the detroit but heaps more predictable and smoother.

A full spool replaces the centre hemisphere, which you then bolt your crown wheel too, a mini spool replaces the spider gears and keeps the hemisphere. But yes the locker will replace the spider gears. Yes it is NEW, I am developing at present and the materials are my big problem, I need a slightly harder material. Give me a little bit though as this has been a 4 year project and during that time I suffered from medical issues.... So do expect it tomorrow but I will devuldge more information once I have the final product availible.

Cheers
