so does this new aftermarket subframe manufacturer offer air suspension as an option? Or do they only offer coil overs?

". . . and the beter driver with same performance will usaly always win!!!!.....so i stuck and stik with lowering coils shocks and leaf springs forget about air rides ecetera"
I agree with this statement, the better drive should always win when competing against equal opposition. At last years RTH autocross the local "hot shoe" drove a bunch of cars, both air ride and "traditional". Maybe he'll see this post his thoughts.

I can appreciate your desire to build a car as inexpensively as you can (I do the same with all my projects). Not all projects require a race-car-like suspension complete with cage, and not all require a "Cadillac" demeanor and ride quality. Though putting a vehicle on air is more complicated in regards to parts (plumbing, etc.) I enjoy the adaptability of the system. It may never out maneuver a C6R, or be as sedate as a Lexus, but It'll get closer to both extremes than any other option out there.

A question to those on this forum: Are there any competitive "race cars" utilizing rear leaf springs in current motorsports racing? (this can be any form of "flat ground" racing vehicle; dirt, road course, oval, etc. excluding vintage racing or classes that require the use of leafs) My feeling is that when given design freedom, the chassis manufacturer has moved away from leafs and into 3 or 4 link cars.
