Don't forget that you'll need the "late" TR6 caliper mounting bolts. They
have an imperial thread, but a metric unthreaded diameter. IMHO, you should
also consider upgrading the rear wheel cylinders to 7/8" units to balance
the upgraded fronts. If you want to go to vented rotors, let me know and I
can give you the part numbers for the Toyota rotors and calipers to use.
Except for a small machining operation on the rotors, its as simple as the
non-vented Toyota upgrade.
Hope this helps,

Subject: Toyota caliper upgrade
I was reading the description for installing Toyota calipers on TR4->6. The
whole thing seems very simple, so I'm putting it on my winter project list.
I'm all in favor of better brakes. The one question I have regards the
piping. I'm assuming the Toyota caliper has metric threads. Since I have an
early car with "imperial" threads, I'll need to change out the short pipe
which runs from the flex line to the caliper. Is there any other piping
which needs to be changed?
I'd be keen to hear from anyone who has done this modification and what
they thought of the results.
