This kit includes everything necessary to bolt four piston aluminum RX7 calipers and 11.25" 940 rotors (stock 240 is 10.25") to your 240.
You will need to source the calipers and rotors. The needed calipers are found on 86-91 Rx7 TurboII, GXL, GTU and convertible. The rotors you need are off of a 940. We always ask for rotors for a 92 Volvo 940. The Brembo part number is 09503610. This should be the rotor with the vents visible from the wheel side of the rotor. You will need to drill the holes in the rotor to clear the step on the 240 studs. This is easily done with a step bit and a hand drill.
Warning: Wheel fitment varies; They do not fit with Virgos, Sirus, or other wheels that have spokes that are tight to the rotors.
To accompany these adapters, we sell DOT approved, braided stainless steel 240 to RX7 brake lines. For convenience, you can purchase these here with the options drop down.
A guide for installing these onto the rotors can be found on our Youtube channel:
