Unfortunately, the comps at work are horrible, so I can't open that link. I looked into the total control stuff a while back and from what I remember it was pricey! IIRC, they had a report about it in MP's catalog. They gave it a good review.
Coilovers are a great upgrade to the outdated suspension, but don't plan on winning classic competitions. LOL!!
Well, I will post more pictures when I get the new ride on a lift, but this will give you an idea the direction I am headed. I want a sleeper look with 600 HP on tap. Full TCP coil overs on all four corners, 6 piston calipers in the front, 4 piston in the back. It sort of looks stock?
Take a look at this TCP setup. It is the same as Air Ride Technologies but it uses coil overs instead. It will be one of my winter projects. I have hear it has a much better ride than the one you are looking at and it is less than $1600 to my door from Mustang Depot.

I have TCP's front coilover with their power rack and subframes.... good stuff.... front end feels awesome..ive talked to a few people that have the TCP pushrod rear....most say its too stiff and binds too much for street driving. if you have bad roads it might not be your best bet. it does look incredibly beefy.
