Rear Rotor Upgrade P2

Caliper and mount off.
Use CRC between rotor and hub to weaken the seized joint.
Then hit around the outer edge of the rotor with a rubber mallet while spinning it. Dont hit to hard dont wan't to damage the hub mount.














48mm Stud length. I plan to upgrade to hardened studs eventually due to taking the wheels on and off alot. 28mm thread length. Standard Mitsu pitch i believe is 1.5mm
Clean rotor of all grease and used a special tool to retract rear piston.






















Make sure hub is cleaned before installing rotor...You dont want it to not sit flat!
Takes about 100/200km to wear the rotor in.
I re-used the pads..But before installing i sheared off a layer using a brick and wire brush
After the track day...Wore in the rotors nicely


Volvo S40 T4 1.9 200hp model. It also shares the same brake system as our colts

For the front your options are: Disk EBC Turbogroove GD925 (281x25) Pads: are starting with standard pads over green, red, yellow and blue

For the rear your options are: Disk EBC Turbogroove GD854 (250x10) Pads are starting with standard pads over green, red, yellow and blue

I personally would stick to yellow or red. In my opinion they are the most suited with the grooved disks. Forget about black, green (like stock less brakedust) and blue (Racingpad needs long heatup).

Currently using the Carbotech CT838

The part No are:
Turbogroove Front: GD925
Turbogroove Rear: GD854
Redstuffpads Front: DP31139C
Yellowpads Front: DP41139R
Redstuffpads Rear: DP31076C
Yellowstufpads Rear: DP41076R

Dixcel quote the Colt Ralliart rear disc at 250 x 10mm, 114.3 stud pattern, 69mm centre bore, front discs are 281 x 26mm.

  5. information by a helpful member juri:

    I found at that the cheapest method is to get Brakeparts from the Volvo S40 T4 1.9 200hp model. It also shares the same brake system as our colts.

    EBC rotors come from RDA (i know they are an EBC dist), sticker with Part Number RDA7999G - come in an EBC box.
    Them's the ones... RDA bring the EBC rotors over as blanks, and the slotting and gold passivating is done locally in Melbourne.
