AMSOIL DOT-3 and DOT-4 Brake Fluid

AMSOIL now offers Series 500 High-Performance DOT 3 and Series 600 DOT 4 Racing Brake Fluid. I recently sold some to a couple members of the local 350z club, but since this is a new product I don't have any feedback on it. I have edited my post in the Group Deals section providing additional information and pricing.

Do you know if the system needs to be purged to run the DOT 4 fluid when changing over from stock? The specs are pretty close on the 3 and 4 but the price looks like a much better deal on the DOT 3.

You essentially do that anyway when you bleed your brakes. I'll get back with you soon with confirmation.
