I recently bought a Stage 3+ but will not be installing it. The disc is very heavy and I am worried that the high rotational inertia will damage the synchros in my newly rebuilt T56. I learned that the Spec 3 and 4 use the same pressure plate so I purchased a Spec 4 (solid hub) disc and will use it instead. The Spec 4 disc only weighs 3 lbs 0.7 oz. The Spec 3+ disc weighs more than 6 pounds. The Spec 3+ disc looks awesome and will probably outlast the Spec 3 or Spec 4 in most applications.
