CGT front subframe questions

[Stpndsmnn at aol.com]

I was crawling around underneath my car today, which I can do without aid of 
a jack since it has over 6 inches of ground clearance!  Anyway, I was looking 
at the subframe bushings and I was wondering if there is a way to put solid 
bushings in instead of the rubber?  I am not really concerned with higher 
noise/ vibration levels, I am noticing that the bushings are not in perfect 
shape and if I am going to change them why not go solid?.   Has anyone ever 
done this (a thread I should check?) or does anyone know of a reason it 
shouldn't be done?  What about A-arms, are there urethane bushings available 
for CGTs?  guess that's about it, I am just looking for relatively easy ways 
to enhance the feel and response of the suspension, since I have to do some 
bushings anyway.
