Light weight and more powerful than any other 4 piston caliper kit on the market, for VW Mk1 application, this kit has been rigorously tested for thousands of miles, before offering it for sale.
We are the only place that offers 1.625" diameter pistons. All of our competitors supply 1.25" pistons.
This translates into more clamping pressure, and balanced front to rear bias. Nobody else offers this level of performance for A1 chassis cars, period!
Clamping force of Tech-53's kit vs other alternatives:
Stock Caliper: Tech-53 = + 14% ( floating type )
Competitors 4 piston kits : Tech-53 = +22%
Porsche 996 caliper and adapters: Tech-53 = + 40%

Tech-53 big brake kit calipers weigh in at 3.9lbs: This is a difference of close to 60%, and 70% respectively on crtitical unsprung weight.
Only Tech-53's kit has rear bias reduced for optimal performance in both braking and handling.

The forged billet bodied caliper
delivers high-strength clamping force and positive stopping power. Four
stainless steel pistons provide fully balanced pad loading, along with the
corrosion resistance and thermal retardant qualities of the stainless alloy that
will keep your calipers cooler and running trouble free. Calipers work
perfectly with 22mm or upgradable 23.81mm OE master cylinders. (Audi Masters are a straight bolt on for a firm pedal feel for racing applications)
