There is a bunch of threads here about replacing the studs - just search 'replacing studs'. It's a popular subject... But it's also one of those "If it ain't broke, don't fix it" cases, because it's a curse of a job to do.Good to know on the belts. We will just go ahead and do them while we're in there, not worth the risk.
Any recommended threads/guides/kits for stud replacement? I wasn't planning on taking the heads off, can it be done with them on?

One of the things to check with the studs is whether they have a letter stamped on the end - my OEM (now replaced) studs had a 'M' (or a 'W' depending on orientation) stamped on them.
One consideration for your front end upgrades - a heavier linear spring will make the front of the bike ride significantly higher, which will make it steer like a barge... The cheap fix is a SSie rear shock, which is a bit longer than the carbie one - or else the afore mentioned Ohlins (which has a ride height adjuster), or any other ride height adjustable unit, to raise the rear height, and bring the turn-in back to what it should be.
One thing you may want to consider is upgrading the silly filament dash lights to LED - so you can see them in the daylight... This thread will help - https://www.ducati.ms/forums/57-supersport/482265-wanted-led-bulb-list-95-900ss.html
