Suspension options.

[IndyNova]

Hey guys, I've gotten to the point on my car to do the suspension. I was going to order a moser 12 bolt, but I've actually started to think about using my 8.5 10 bolt and adding a new tru track unit with new axles and c-clip eliminators. I am also looking at the ridetech coil over level 2 suspension. Is this a reasonable plan to achieve what I want? It will be mostly street driven, but want to do auto cross also. I'd like to take it down the strip also.
Also, if I go coilovers, does this setup lend itself to adding air ride later if I choose. Any pro's/cons with this setup?
Thanks for any help, it's always appreciated!
