I had two Genuine Nissan OEM clutch master cylinders not only fail but,leaked and only got worst over time. I highly recommend installing the RJM Performance CMC it will save you in the future because eventually it will fail down the road. I kept the RJM Performance petal with the Competition clutch and I adjusted it as needed definitely a good idea. Also I believe the Z Speed Performance CMAK is the best option to go with. If you do install a Competition clutch kit make sure you follow the 500 mile break in period it is necessary for this clutch kit so your new clutch breaks in properly. Overall the Competition clutch kits were my favorite.
