ST brakes, please help !!! Options

[yagamius]

I've been reading about the braking stuff and many many swaps for the rear drums to discs, here I've found people who change the hole system and some others that found a way to do it without change a thing.
so my questions increase instead of be resolved, couple of days ago I take off the drums to a regular clean and start searching to see if its possible to just put some rear Rotor from a Celica that will fit right away in my hand brake system.

some say about ST165 some others say ST185, and many others make a swap for a GT application.

I know that if there a way to fit a rear rotor to the actual system I'll need to find a way to put the caliper brace and the caliper.

so is there a way to do this, or if the GT rotor from 6th Gen will fit (i don't think so cuz it looks smaller).

by the way my Celi is an AT200 Celica ST 1994

checking the web many people sell both front and rear rotors, can I use the front rotors from ST185 with my actual calipers ?

You don't have to change the prop valve, your brakes will still work fine if you don't. If you can source a prop valve from a GT, then go for it. Tons of people who've done this conversion, myself included, did not change the proportioning valve and aren't having any issues with braking.

but what about the size of the actual drum (st) vs the drum from the rear rotor of the 94-99GT or ST185

GTs have rear disc brakes, not drum brakes. So you need rotors, not drums. Rotors can be found VERY easily by searching/asking for rotors for a (your year) GT.
