Original Super Stock HEMI Dart LO23

It's been a VERY long time since I've been on this site & thrilled that there's an explicit LO23 thread started since, as some may know, I've built three clones and enjoyed every one. Which is kind of why I'm here.
My present car I just can't seem to keep cool enough for street use so I'm looking for suggestions(pm me as it's too long a story if you'd like to help) . But the other reason is relatively simple. It's been some time since I've done any real mods to the car & I'm thinking of some front-end improvements. Anyone familiar with "Gerst" suspensions? I've viewed the website and it all seems good but I'd really like to hear from someone that's actually used his stuff. I suppose I could ask him but my suspicion is I'd only get referenced to people who had no complaints/issues with the stuff & I know nothing is ever as simple as it seems...…...Sooooo anyone know anything about them?
