Per your suggestion, I started looking at SHOsource and I found front spindles. I an assuming those are what I should be replacing?The front tires with slop may be wheel bearings. Make sure the wheel is on at correct tightness, jack up the end to be tested, grab the wheel at 6&12 and 3&9 push and pull to see if there is movement at the center. These cars have a press fit bearing and not just a bolt in and out wheel bearing. You might need a press or shadetree setup to pound it out and in with replacement. I would look at shosource for most items. They usually have good sourced replacement parts and upgraded parts. Solid mounts will transfer alot of NVH - noise vibration harshness. They may have reinforced ones with some urethane or other polymer to help reduce vibrations. Struts are hard to decide what is good as all the really good ones aren't really made anymore. My main pet peeve about these cars now is strut choices. Look at the strut mounts and you could add those to the list of spending money...
For larger brakes you have to check for clearance of the oem wheels and decide based on that. You can source alot of the parts yourself or buy a kit. There are alot of how to's on the forum for this kind of stuff. Based on rust, and whether you have power tools, all this may involve alot of cursing.
As for the motor mounts, I think your idea is better, since I'm not racing it yet, just daily driving it.
For struts, I think Jegs have some that should fit.
I was looking at a set of 17 inch rims, so I can do smaller tires. That should give me more clearance for brakes, right?
