A quick note about ST165 brake pads by ray meyers:

Stillen - : Stillen offers Metal Matrix brake
pads for the ST165 but they told me that they did not have them in stock
and it would take two weeks to get them. They also acted like they
didn't want to sell me anything that they might have to special order.

Porterfield - : Porterfield makes
carbon-kevlar brake pads in three different compounds for the front and
rear of the ST165 and ST185. The R4S compound is for high performance
street and limited competition use and is available from Racesearch
( Racesearch had them in stock so that is
what I bought. The part number for the front pads is AP437 and they
cost $84.50.

EBC - : EBC makes brake pads in three
different compounds. Only the "Greenstuff" pads are available for the
front of the ST165. This is their high performance street kevlar pad.
The part number is DP2725 for the front pads but I did not call them to
find a distributor.

Supra Brake Upgrade

Supra and Supra TT have significantly larger brake rotors and calipers. If these brakes were applied to the front of an All Trac it would mean super braking power for alot less than a "big brake" kit. There is no hardware to support this conversion however. If this is to be done it must be 100% custom fitted. More information is in the Brake FAQ.

ST205 Brake Upgrade

Since the ST205 GT-four is still a celica, this brake upgrade is considerably easier to perform. ST205 brake system includes a 4 pot brake caliper in front, along with larger discs. For more information see the Brake FAQ.
