MRC woes... need advise

My 15 SS is lowered on Granatelli/King SSSL springs. In the last month Iíve noticed the front suspension (seemingly more on the drivers side) bottoming out much easier than ever. Had the car on a lift and checked the shocks out, yes the drivers side had a trace amount of oil. Literally hardly anything. The mechanic said in his opinion it was ok. I know this is becoming more of an issue. I live in South Florida, anyone with an idea where I can take the car to get checked out? I realize a Chevy dealer might be needed, but I really havenít had much luck with them around here in the past.
Thanks

In my opinion, any oil is evidence of a failed shock, it will only get worse. If still under warranty take it in....

Not covered under warranty if the springs were changed.

These issues have kept me from lowering mine 😞

Soooo. If you see the presence of oil this would probably warrant a shock replacement. I recommend replacing them in pairs. You have driven plenty of miles to allow the springs to "settle". Has anyone accessed the suspension control module and reset the trim ride height after the spring replacement?

A modicum of knowledge goes a long way.

The MRC was never reset for the new ride height. After I had lowered, I rode in another 15 that had the module reset and he and I agreed the two cars rode the same. The dealer wanted 275 to do it so I decided to skip it. His car has since blown a rear shock. So imo the jury is still out on that.

A local shop did the install. They are well known around here. No shady tree mechanic... but with that said I wasnít happy with the job they did. Thatís another story though.
I guess at this point I need to find somewhere to take it and diagnose it.
