EMPI vs CB Performance T1 Wide 5 Disc Brake w. Drop Spindle Kit


Can someone please tell me what the differences are between these kits?
Cast or forged? Pros and cons
Any info would be helpful.

The CB ones are the only ones to consider.  They use an aluminum hub with an iron disc bolted to it so the mass is kept as low as possible. 

The EMPI rotor is a massive single piece of cast iron that weighs more than your engine's flywheel!  The EMPI rotors act like huge flywheels, good thing they have a disc brake on them to help slow them down.  The extra weight in them increases the sprung mass of each wheel.  The result is that it makes the car ride worse.

Thanks Bruce!
