Adam,
The Cressida rotors are vented - stock TR6 are not. If you want to install
vented Cressida rotors, you need to use the later Toyota 4-Runner calipers
that have a wider slot (for vented rotors). The Cressida Rotor is 22mm wide
(as opposed to the TR6, which is 12.7mm. Lee Jansen's website (referenced
below) has details on both the solid and vented conversion. Here is an email
that I wrote last year on the subject:
The vented rotor conversion uses rotors from a Toyota Cressida. The inner
hole of the Toyota rotors needs to be machined to 3.125". The bolt holes in
the Cressida rotors are the same as the TR rotor and do not need modifying.
The Toyota calipers are 4-piston units from a 4 cylinder Toyota 4-runner.
They look the same as the non-vented Toyota calipers used in the conversion
Previously listed on the VTR website; they're just wider to fit the vented
rotors. Part numbers are as follows:
Rotors - Aimco 3247: 1986-1988 Toyota Cressida Front Rotor (Sedan Only)
Alternate Part Numbers; Raybestos 96042, Bendix 141410
Calipers - Fenco C8554, C8555: 1988-mid 1989 Toyota 4-Runner, 4WD, 4Cyl
Alternate Part Numbers: Cardone 19-827, 19-826
You may also need to purchase a fitting kit (pins, shims, etc) for the
calipers and brake pads.
The installation is the same as for the non-vented conversion at
http://www.cs.du.edu/~ljanssen/tr6_brake_install.html . Sometimes you will
need some thin AN washers to shim the caliper (center it on the disk). Some
installs need the shims, some don't.
If you would like to see some photos of the conversion, go to
Hope this helps,
