someone mentioned using ventilated discs with

may soon be looking at a 59 TR3 project and would like to see what is
involved.
TJ,
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
listed on the VTR website (which happens to be down as of this writing);
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 have access to the 6-pack website, there are some photos of the
conversion on my TR6.
Hope this helps,
