Hey Will no prob about the hoods, you had more then a legitimate reason. And yes they are still available, I'll be making a big post about them in the near future.
Your problem with the doors unlocking themselves is caused by the main lock relay in the DS door, its almost right under the lock and window switch console panel. These things seem to get sensitive to vibrations with age. If you knock hard it will activate. What happens when you use the power locks is the vibration from the locks be snapped shut or open in the door triggers the relay to activate. In some cases mine would do this several times before it would stop, as each time it activates it causes another vibration. Slamming the door would often activate it too, which can put you in all sorts of awkard positions. Keep a spare key in your wallet till you get it fixed. You should just need to replace that relay and all should be good. Finding one at a junkyard can be hit and miss as it is a common problem.
Your leather sounds like its in the same shape as mine. I want mine looking fresh and new so I'm just going to replace the front seat skins.
About your clock being reset, I imagine the stock stereo is still there? If not does the clock on the stereo reset everytime the car is shut off? If so you have some kind of wiring problem where all power to the car is being shut off when the key is turned off. Might be short, I'm not sure. One of my supras is doing this and I haven't fixed it yet. Might just be a wiring problem with the clock too.
I'm really happy with the ST springs but it might be too soft a ride for those expecting some serious performance springs. I think they suit the character of the car well though if racing isn't a huge concern. Deftinatly causes excessive camber in the rear, but I love the handling.
