Greetings- I'm the proud new owner of a 73 240z that had a previous life performing road-race + solo1 activities. It's not completely stripped- it's still streetable. The PO performed the toyota 4 piston caliper upgrade up front, but with solid rotors. The rear still has the stock drum brakes. I want to upgrade the brake capacity before I take it out on the track. Plus, the current brake condition is kind of an 'unknown' so I want to start with a clean slate. I've done a staggering amount of research... so far, the best cost/performance it seems the best is to do the following: Front: toyota 4x4 with 300zx vented rotors Rear: 240sx calipers/300zx solid rotors Master Cylinder: 280z For those of you running this setup, are you happy with on-track performance? I want to avoid the time + effort of installing this setup if it's inadequate! For context, I will be leaving the engine stock internally, but will be adding a set of triple weber side-drafts plus a crank fired ignition system- so power won't be increased dramatically. But, some of the tracks around here have pretty aggressive braking sections... Higher performance alternatives seem to be the arizona z-car full race setup, or a wilwood + JSK parts is JSK defunct?? I can't seem to find a working website... edit, I found this: http://www.jskinnovations.com/ initially the website front page looked broken... Thank you for any feedback!
