Adverse effects are entirely possible, and just what the drawbacks are depend on the specific LCAs and their bushings/ends. "Unexpected" rear roll stiffness and a "loose" handling tendency, noise, durability, periodic inspection & maintenance requirements, and replacement cost are some of the possible effects. The devil is in the details, as they say . . .

+1 to what Norm said.
For example if you put in poly/poly LCAs then then they can adversely affect handling as the stiff bushings try to prevent the car from rolling when taking the corners near the limit. A poly/rod LCA is better but adds to NVA and a rod/rod LCA is the best but really adds to NVA.
Another alternative is the GT500 LCAs which have stiffer rubber bushings.

I have had some noise issues with two different sets of LCAs, mainly because the aftermarket bolt sets are slightly smaller than the ford mounts, stupid really. So you get some clunking decellerating because of that tiny gap, also you need to have the shop tie the emergency brake cable up and out of the way, you can get some noise there.
I decided to get LCA relocation brackets welded-in for racing, that fixed most of the clunking issue, probably not a bad upgrade to couple with adding LCAs.
Helped my 60 ft times, always sub 2 second now......

I can't imagine NOT welding LCA relo brackets in.
There's something about bolted joints and vibration that makes me uneasy when the things being bolted together need to stay put in a particular position to keep the car from getting a bit squirrely.

I hear that, alot of the reloc brackets come with hardware to bolt-in but what are they thinking, lol? the S197 has alot of aftermarket parts available but some were rushed to market and not engineered correctly and we are the beta testers !!!

so after this thread i didnt really want to get the LCAs since i care more about how the car handles than going straight...but now that my front end feels pretty good...i was thinking i should work on the rear end a little...
i love the way my car handles but i am thinking the LCAs would make it feel even better...i was looking at some steeda billet LCAs with the poly bushing...does anyone think there would be any kind of drop off in steering feel? right now i have steeda X5 ball joints, bumpsteer, front control arm bushings, g trac brace, sway bars and d specs...
