Alternatives:

Rotors and pads are now available from EBC and are highly regarded as aftermarket replacements / upgrades. Locally, DBA have had rotors in development for over 6 months and may well now be available. Exotic 2 piece rotors with alloy hats are available from various Japanese and American suppliers. The Supra 4 pot braking system is well supported by aftermarket suppliers worldwide.


Steps to Upgrade:

Preparation

Ensure your wheels will clear the large front callipers 45mm positive offset is required as a guide and anything under this will either need replacing or longer wheel studs and spacers will need to be used.

Decide if you will be using new or used callipers.

Decide if you will use genuine Toyota or aftermarket rotors.

Decide if you will trim the undersize front dust covers or if you will replace them with correct sized ones.

Decide if you will be replacing your park brakes shoes whilst you have the brakes apart.

Purchase and collect all parts for the upgrade.

For used callipers, have them sand blasted and overhauled by a brake specialist using the Toyota cylinder kit and spray paint them with protective calliper paint.

From the Removal, Installation and Service Manual attached familiarize yourself with the location of all parts and the disassembly and assembly procedures before beginning.
