Z1 Front 13" big brake rotor upgrade kit



The Z1 13" front rotor upgrade now includes a pair of 1 piece cross drilled and slotted rotors standard.  The more expensive 2 piece 13" Baer Eradispeed rotors can be selected as an option below at additional cost.

Single Piece Cross-drilled & Slotted Rotors (or Slotted only) are included in the base price.

2-Piece Baer Eradispeed Rotor (available as an option)

      For an additional $289 we offer a 13" diameter 2-piece Baer Eradispeed rotor with an aluminum hat and a special high-friction alloy disc which has been cross-drilled and slotted for improved braking performance. The aluminum hat lowers the assembly's mass and this larger rotor assembly weighs the same as a stock rotor!   The aluminum hat improves the heat dissipation capacity of the rotor resulting in superior fade resistance.  The Baer Eradispeed rotors are guaranteed against warpage!

     The additional 2" of rotor diameter vs. stock (11") provides a significant gain in braking leverage which is very evident when the brakes are applied - less force is required to produce the same braking power. Directional internal cooling vanes within the rotor provide additional cooling for greater resistance to brake fade.
     This kit uses stock calipers which are balanced to the rest of the braking system. The stock calipers are more than adequate to provide the clamping force necessary but with a larger rotor they actually don't have to clamp as hard to produce the same braking force - leverage works to your advantage!
By using stock calipers, the entire braking system stays balanced and stock pedal travel is maintained.
Kit Includes:
  • (2) 13" 1-piece cast rotors  (Optional 2 Piece Rotors Available)
  • (2) Caliper relocating brackets
  • Grade 9 fasteners
  • CNC Aluminum Hubcentric locating rings
  • Installation manual 

Depending on the offset of the front rims, additional hardware may be required.   We do not include this hardware in because the offsets of many aftermarket rims don't require it.  The hardware kits are available as options at the bottom of the page.  To determine if the additional hardware is necessary measure the current distance between the front face of the caliper and the back of the spokes on the rim (the shortest distance between the front calipers and rims at the closest point) .  After finding out how close the calipers come to hitting the back of the spokes on the rim with stock brakes refer to the following chart to determine if additional hardware is required.

Existing distance between caliper & rim Hardware Kit Necessary (options below)
10mm or more NONE
5 - 10mm A -  5mm hubcentric wheel spacers
0 - 5mm B - 10mm hubcentric wheel spacers w/ extended studs

We recommend the purchase of our rebuilt calipers to go with this setup. We offer them for only $200 a pair with a additional $100 core charge. This will ensure that your entire front braking system is in excellent working condition. 
Pads are not supplied with this kit. We offer a selection of new OEM pads, Hawk pads, and others. Please see our brake pads HEREStainless steel brake lines also make a nice complement to this kit and we offer them HERE.

NOTE:  This kit requires that you have at least a 17" wheel in order to fit.  This kit will not fit under stock Z32 16" rims.  1990 Non Turbo (NA) front calipers will not work with this kit as they are smaller to accommodate the narrower 26mm wide rotors.
