GT4 front caliper alternatives? Options

[luka]

are there any alternatives to the factory GT4 calipers that aren't $1,300+?

Its one of the few hardware pieces i'm missing for my project.

I doubt my stock GT calipers are strong enough to handle & judging by the size difference in hubs, even big enough to consider using.

any help is appreciated

if you can get your hands on ST205 disc those also work, the only issue with them is the cost + shipping since they are not available in US, that's why I adventure with a rotor I could source within US.

Cadillac Catera disc are readily avialable anywhere and jsut need to take to a machine shop or sometime the rotor supplier can drilled with for a small fee ( I paid 15 dollars )

so in the end cost of Catera disc + custom bolt pattern fees = a lot cheaper than ST205 disc.
