there is nowhere near enough room to mount coil-overs, especially dual coil-overs in there with one in the stock position and one in the position i add the other one to.

the best bet is to run a coil-over mounted toward the front of the strut tower and bolted with the thru-bolt for the fork on the lower A-arm. you might be able to fit another shock at the back end, too, but i'm not sure with the upper A-arm being so small. you also have to be aware of the steering parts, the pitman/idler arms and tie-rods.

on another note... there are factory coilovers that come on some chevy tahoes or something that have an average sized shock with a thin coilspring over it. i wish i had grabbed some from my friend's shop that he had removed before he closed, but i'm thinking about looking into it. they are a very narrow package and may be able to fit 2 per side up front and they may be long enough and stiff enough.
