Cant my original lines bolt up? No, they do not. When doing a brake conversion that requires drum brakes you will find the cables do not match up to your S13/240sx OEM lever and front cable. This means you need our conversion plate that enables you to keep your OEM lever and front cable while running the R33 2 door e-brake cables. Will this work with any other cables? No sir! This plate has been designed to only use the R33 2 door e-brake cables, as mentioned above. Why use an M8 hole to locate the cables instead of the M6 provided by the factory? We noticed the OEM e-brake cable has the allowance for a larger bolt to be used to secure the cable, why not use something that is already there to make a better/stronger product! Is 8mm too thick and will this cause any issues? There are no clearance issues and considering people are constantly pulling the e-brake whilst drifting we felt the need to overcompensate an important connecting part. Does this come with everything I need? Yes, this kit comes with all the accessories to bolt directly up.
