I did some more research and found this info about the Dynalite version of the Wilwood calipers. I'm sure the same merits that make the forged caliper btter for the Dynalite would apply for the Superlite aswell. Not only that they are 40 bucks cheaper.
What is the difference between the Wilwood Billet Dynalite Calipers and the new Forged Dynalites?
Many of the calipers on the site shown are the Billet Dynalite Calipers. The calipers that we are now providing in many of our kits are the upgraded Forged Dynalite Calipers. These calipers are new from Wilwood (well, they have been out for a few months), and since their release, we have been using them in place of the Billet Dynalites in our kits, and when sold separately. The great thing about these calipers is that they are the exact same in dimensions (piston sizes and outer dimensions), but they are much stronger. The forging process makes them a lot more rigid.
