Spriso Motorsports Big Brake Kit Rev III

Brake Caliper Brackets

Spriso Motorsport 300ZX Big Brake Kit– the ultimate stopping power for your roadster!

Anyone who drives their roadster enthusiastically on the track or on your favorite mountain road has probably experienced brake fade. After nearly killing myself on a mountain pass with a Volvo brake caliper conversion, we vowed “never again” and developed the largest possible brake kit that we could still stuff under 15″ wheels.

We have two styles available:

300ZX Twin Turbo Caliper Kit (30mm wide rotors)

This kit includes rotor hats and caliper mounts to use 300ZX twin turbo front brake calipers.

You will supply the rotors, calipers, and assorted hoses and fittings. This front brake kit uses custom brake rotors built to our specs by Coleman Racing Products– with your order we will supply you the rotor specs, installation instructions, and a detailed list of parts to complete your conversion.

300ZX Non-Turbo Caliper Kit (26mm wide rotors)

This kit includes rotor hats and caliper mounts to use 300ZX non-turbo brake calipers.

You will supply the rotors, calipers, and assorted hoses and fittings. This kit uses custom brake rotors built to our specs by Coleman Racing Products– with your order we will supply you the rotor specs, installation instructions, and a detailed list of parts to complete your conversion. This kit also uses a Coleman Racing Products rotor designed to our specs, but is slightly narrower (26mm wide) which allows for better wheel clearance on early cars, or cars with lower offset wheels.

Kits are $495 each.

Winter 2022 Note:  Unfortunately we have had to incorporate our first price increase in 8-years. We have had a 200% price increase in material costs, so I will have to raise my prices to reflect that. We are going to absorb as much of that as possible to keep this as affordable as possible. Raw material, and machine shop costs have been going crazy, and there is nothing we can do to circumvent this. 

Notes: These kits REQUIRE the use of the ALUMINUM versions of the 1990-1992 Nissan 300ZX (Z32) four-piston brake calipers– the IRON versions found on later 300ZXs will NOT work.
