||I’ve got 3 on the shelf right now from Kaaz.
They are 2-way, which I have had converted to selectable 1.5 way or 2-way. I had the 1.5-way ramps CNC machined, waiting for the parts to return from heat-treatment.
I run a Kaaz SuperQ 1.5-way in my 240z turbo, and have always been pleased with the product and the support.
I don’t believe that Kaaz produced many R230 units, my stock is all serial-numbered under 20 with early 2000’s production dates.
