Yes, I know people complain about this with lowering their cars, but I might have the opposite issue and needs someone who knows more about suspensions to confirm/deny.
Long story is my car has been on and off the road for the last two years at various stages of supercharged and turbocharged; compounded by the fact I've been deployed and moved 4 times in that time-frame; so the 8 hasn't gotten its share of TLC.
When I was driving it last summer it was sitting low and would make a horrible knock going over bumps. My front main seal was also throwing oil so we tore out the engine and chased the suspension knock. Turned out the bottom coil and a half of my rear springs both rusted and sheared off, the car was bottoming on the bumps. So I bought some Mazdaspeed shocks and struts to swap out while everything else was going on. We swapped the rear out by bolting the top of the strut into the trunk and jacking up the end till it fit into the hub (not recommended I know)
I moved (again) in the spring and just now got around to finish getting it running. It has been sitting the entire time normally, without much movement. This week I got it running and noticed a terrible rhythmic scrape sound every wheel rotation. After jacking it up and checking wheel spin I couldn't find the problem and everything seemed fine. Then after taking it for another spin same thing happened. Pulled over and found out the rear wheels were all the way into the wells, and my tire was rubbing. I think every time I jacked the car up it would by me about 2 miles of no rubbing.
Long story but is this a case of a kind of 'pre-load' where my car sat for so long with broken coils that this is its "normal" position? Should I try and "un-load" them by loosening all the arms while the wheel is in the air? It is a matched set of MS springs and struts from Mazdatrix so I don't think it is the usual cheap springs argument. Please help before I start tearing this stuff apart.
