My version of the front brakes looks like this
Disc 300mm Opel Astra-J GM 13502051
Caliper 2-piston 45mm Opel Antara / Chevrolet Equinox GM 96625936 - left GM 96625937 - right
my version is on the left 1,5gen - on the right
Use stock 16inch Wheel
The mileage on this version is about 30,000 miles
System without abs, stock master cylinder
Cooling ducts pointed towards the back center of the rotor (essentially at the hub) will be the most helpful. Hard to do on a front wheel drive car that isnt an all out race car (to where you can put an inlet hole or naca duct wherever you please ) Also remove the dust shields.
Ive used motul race fluid extensively. No issues with it.
As far as pads for our caliper I do not know who makes performance pads that fit - but pagid, hawk (blue), carbotech all are good race pads. Im sure for track days EBC are fine - I do not know of and have not seen anyone using ebc in actual racing (but im also not inspecting cars or asking people about brake pads at the race track lol )
Use plain cast iron rotors and not drilled or slotted or anything silly like that.
Cooling. Cooling. Cooling.
