  1. Wheel Studs - $160
    I'm still using OEM lugs, though they are not the originals
  2. Caliper Stud Nuts- $40
    I have studs installed but never thought to replace the nuts
  3. LCA's - $450 each (x4)
  4. Caliper Rebuild - $120 (assuming the pistons are in good shape)
    Did this 2 years ago so I guess it's due
  5. Axles and CV Joints - $600 (x4)
    It's a Turbo
  6. Wheel Bearings (x4) - $90 each
  7. Wheel Carriers AKA "Knuckle" (x4) - $490 each
  8. LSD - $3000
  9. Suspension - I don't even want to know. Guessing $5 to $7K.
Not including the suspension (or any labor), we're at $9,840. Way more than I was expecting and I can't swing a giant invoice right now especially since I won't be doing many DE's this year. I'll have to do in pieces.
So how would you prioritize this list?
wheel studs?? i dont know of anyone that has ever changed one with the purpose of preventative maint. sure , you could change every bolt on the car if you wanted to, but the prudent way is to change things that are going to wear out and cause problems if they do. LSDs for example, if they meet spec, why bother ? suspension, maybe every 10 seasons, but again, you can check to make sure all is working well. axles, CV joints , wheel bearings? most of these dont fail catastrophically but do go bad eventually, so they are good to change after a car is 10 years old. generally I wait for the noise, or if it is a WYAIT situation, change then. caliper stud nuts? why? do the fail? just check to make sure they are torqued.
i would focus on engine items that can fail and destroy an engine.(timing belt, chain, etc)
keep the oil changed as well as other fluids as well as brake pads when time, and you should be good for a long time.
put it this way.. you provide a list, and i can provide equal as many things that are just as important to change that you might not have even thought about.

Step 1) Totally ignore the previous Post.

You have some nice items on your list. Prioritize wear items(wheel bearings), versus fatigue items(uprights). Also LSDs can be rebuilt. And it doesnt cost $3000. Also a good suspension is less than $5-7K. In addition, if you are running on track, dump the 4wd setup. KISS Keep It Simple Stupid....

There is a pretty good list recently in the Cupcar Forum that many DE drivers should look at for 996 997s.

Have they released a vane kit for the Aisin lsd? For years you could only buy a complete replacement lsd. There was no service pack like a Cup or GT3.

Just found out that my harnesses are expired now. There's another $600 to $800. For a garage kept DE car, doesn't seem to make sense that they would time-out. My OEM seat belts are not timing out. I don't think any club has ever checked them anyhow.

My car has become a BOATT - "bring on another ten thousand".

Unless your racing or the belts have been subject to years of UV exposure they should be fine for DE. Make sure to check for any deterioration though.

This is what Porsche recommends in the owners' manual for every 6,000 - 12,000 track miles:
