16” rims and bigger are the go for a successful outcome.
STD Volvo 240 brakes in top condition really work well.
The RX7 upgrade gives say a 10% improvement that becomes noticeable under maximum braking effort and that’s due to the calipers being mounted further out on the larger disc. The caliper 4 pistons are exactly the same diameter as the 240 Girlings.
So it’s an upgrade, but not in the 6 piston Brembo league.

One of the reasons why the RX7 calipers improve braking is that a lot of brake hoses are eliminated.
I converted the old 164 rally car to a conventional front/rear split using original hoses and modified original calipers - the pedal was MUCH better.
