I agree, in terms of sensible brake upgrades for the holden gemini, it really comes down to piazza items, or your setup and I must say, it is an ingenious upgrade... but... I don't want to follow the footsteps of another, I'm looking for a showcase upgrade, something that all the other gemini knutters can see and go "f#ck, big brakes are good, I want big brakes", chances are they'll probably be sensible and go with your setup, I want to be the superlative example of something in the gemini world, like spry, baghdadi, mobbs or woodward...
The master cylinder might prove to be a problem and potentially an expensive one at that, but the bias would be fairly straight-forward to resolve.
Once again, it all boils down to wank factor... |

807's are off the bigger Audi's. they hae a dia. of 288mm so they are pretty damn big (11.5").
Cant say there is a best caliper to use as all will need to be modified a bit or have mods done to make them fit, given the large size of rotor compared to the gemis small stubaxle/stereing knuckle. I wouldn't use anything less than a good 4 spot caliper from a volvo or BMW etc. Best bet though would be a brembo of a skyline or evo lancer etc, or a set of AP racing calipers. However these start at about $1000 for a good set. Its basically trial and error. I used a set of volvo 4 pots and they were great. Now Ive got 7 series/M5/M6 BMW calipers on my car and will be much better better, (more pad,better system,etc). We'll soon see.

Hey mark,
I'm currently doin the brakes on my TE, and i found a kit which fits 300mm rotors on with VX twin sopt callipers, i've already been told the best master cylinder to use with it is a XB one, but i hadn't thought about bias valves, do you have a recommendation on this. I know it seems like a wnk factor on size, but i want the car to stop and handle and then i'm gonna start playin with power, thanks... Matt |

as i am the fuckin guru of fuckin gemini brakes, and ive been told this by others.(i dont toot my own horn cause i get cramp). the you beaut magna commodore combo that has been designed by engineering wizard and personal mate diesel is huge in stopping capabilities. when racing at barbagello raceway in w.a. we were suprised to find the gemi would pull up from 180klm per hour to 90 klm phr in a distance of 50 to 55 meteres from the said corner. any attempt to go bigger on the front brakes caused severe lock up and massive front end damage due to chronic understeer. so if you over brake a GEMI you better have good insurance
