I have a set of these and I love them... but I'm not 100% sure if they are the pro street.
Eibach coilovers for SRT-4, $969 !
This is a link to the ones that I have, I bought them used off another member and aside from some noise (which it seems everyone has) they ride great.
The only con to them I might say is they aren't dampening adjustable like other coilovers, but I think they are pretty matched for the springs.
I believe the spring rates are 342lbs Front and 171lbs Rear. Good rates, but the back can get a little happy with the weaker springs.... very nice ride though.
However I've seen people selling the "Pro Street" ones and the picture has different springs for the front... so I'm not sure if there are 2 different sets or what.
Edit: Just noticed the thread starting date... hopefully this info will still be useful.
