Default Racing disc not good on the street

ng8264723 Running an Iron disc on the street is not good, It's a racing part. Have you looked into a street twin setup? The other thing is I run GM trans in my cobra a 6spd richmond and a 5 spd g-force, I have a roller bearing in the crank for the pilot bushing. Some trans input shafts need to be cut .380" off. Both of mine with the lakewood shield and motor plate are OK. No spacer is used. My flywheel was machined for running both GM and Ford clutch assembly bolt patterns. I did this for racing. 11" and 11 1/2" patterns. My next motor is get the twin disc setup, very easy pedal pressure and 800 hp rated. The whole assembly, wieghts the same as the stock 40+ lb flywheel and clutch. You need to measure from the back face of the beel housing to the edge of the bushing in your crank to see if you need to either run a shorter trans shaft or cut off the input shaft the .380" to keep the crank from riding on the thrust bearing and perwearing it out. Make sure your bellhousing is also center to the motor. I have a gold centerforce clutch in the car WITHOUT THE WIEGHTS on the pressure plate. Was having problems shifting over 3,000 rpm with the ERA hydro setup. Problem was solved when the wieghts where removed. I will never run a lockup clutch again. This is part of the reason I have 2 trans for the car. You can have the input shaft machined shorter at a machine shop for about half the cost of a new input shaft. Richmond has just come out with a new 600 hp and tork 5 speed trans. It is the same size as my 6 spd. The only different is the mount is 1" shorter to the front of the car. The frame was modified for my 6-spd. Stay a way from the multi disc little clutch setup for the street. They don't like to be riden on in stop and go traffic. If the street twin is setup right, this should be the only clutch you will ever need. The old ones made a little noise, the new ones are quiet. Rick L.
