I don't think so...
I had vibrations when I had S-tech springs on my car
now i'm on megan's and around 25.5 fender to ground, still has vibrations
vibrations comes hit or miss
if you have them, you have them
if no, then you're safe
no matter how low you are

it doesn't get worse

and you also might get wobble during accelerating but that could be eliminated by adjusting the coils to make the car sit better


and the point of not going lower than 25 inch is that you might rip your CV boot on the AWD models just for being too low

I just helped a friend do BC coils this pass weekend on his 250. he rides nice and he can now go lower and have damping adjustments. I think you'll be happy with BC too.
