I personally want the on/off switch. The clutch will chatter a bit sometimes. I am OK with it. It beats replacing the dang clutch all the time. Time will tell if you have chosen wisely. Put 30k on it and let us know.

This what happened to my on the SZ Street Max clutch and flywheel setup. It was fine and just like oem until I got my 100 octane tune. I was at just over 550 tq and it would start to smell if I had to slip it or hit it hard more than a couple of times in succession.

I do not want to have to buy the RJM pedal assembly. I need to order it this week. MY CSC has given me short notice that it is about to die.

The RJM pedal will not move engagement UP, Only down lower.

This will have all the grab you need ;) It will have a bit higher than midway engagement point as it comes and I can make it higher and grabbier if you like by swapping out the slave cylinder size on the CMAK from standard to our race version slave.

Thanks, Do you have a re-buildable lightweight flywheel?

We do not offer aluminum flywheels as they are problematic. Aluminum and steel expand at different rates, this causes things to come loose and inserts to warp over time. Inserts are a PITA to replace and expensive.

We prefer only steel flywheels for durability.
Steel can be resurfaced multiple times cheaply and is the most durable.

We have 17, 19 & 26lb steel flywheels available.

Make sure you check it for warpage before your installer touches it, or they will blame any issues on the install. You might want to video the unboxing and testing.

I am the installer. I have and still are using a lightened aluminum flywheel with steel inserts on my 1975 Datsun 280zt. How long??? Since 1995 and over 170,000 miles, 3 different clutches. The 2nd clutch was done due a front seal failure on the tranny. It is still in the car today.

Then CYA. Otherwise you'll never get them to fix it if there's a problem.
