996cup how long do parts last?
I just started using racecartracking.com to track parts on the car and was looking for a couple of datapoints from the collected brainpower on this forum. I am trying to be safe but also not wasteful of money (ok I should have chosen chess as a hobby...) I also want to be able to predict future expenditures
what parts do you track hrs or miles on?
what timeout values do you use?
do you take parts off when they timeout? or just inspect?
do you save taken off parts as spare parts in case you need them at a raceweekend?
if you also use racecartracking and are willing to share screenshots of parts list you track pls pm me (or post here)

Hours tracked on all suspension parts and driveline.
1) Wheel Bearings - Change every year
2) All new suspension parts every other year. Some of the parts with rubber like dog bones every year.
3) Axles Every year clean and regrease with Krytox. Replace after 2 years (if cv joint has play during replace as needed)
4) Air Jacks - Rebuild every 2 years
5) Fuel Filter replace mid and end season. At same time clean fuel tank. lots of dirt in the track fuel tanks sometimes.
6) Air Wand - Rebuild 2 years
7) Shocks rebuild every 2 years if no signs of leakage
8) Spherical bearings (like top shock mounts) replace every 2 years
9) Clean Fuel Injectors year one, replace in year 2
10) Coils replace each year
11) Rear Plastic Window replace every 2 years
12) Metal Radiators every 2 years
13) Every 3 years ALL rubber lines / hoses in cooling system
14) Brake Calipers rebuild each year
15) Brake Master Cylinder replace each year
16) Brake lines replace each year
17) Clutch Master replace every 2 years
18) Replace 3 disc clutch each year along with through out bearing / pressure plate every 2 years
19) Replace 9v battery in Fire System (yearly is fine if you remember to turn off. Always carry spare)
20) Fire System - Review expiration date at beginning of season. Get refilled if expiring
I dont have my actual data available, but this is off top of my head. This was for our cars doing roughly 50-60 hours a year.You mileage may vary. We tended to replace more often, but we also never had a part failure at the track in almost 5 years.

Nice list! Thanks.
I think I have literally gone thru this a few times!
Not for the faint hearted! But nothing is worse than going to an event and breaking!
Time is the real commodity in my world

Great list Bob - wow I am way behind on everything . Other thing to consider as Bob said is hours and what level you will be driving at . We know pro support and campaign will be a lot different then club level

Seems that 997 and 996 are more or less the same to maintain except for the gearbox? I’d like to know what the rebuild intervals for each car’s transmission and associated costs? Read lots about 997 gearbox requiring far more upkeep than 996. Is it true? I know a few that race 997 at club level and they’re opening them up for a look every 20-30 hours.
I am still deciding between 996 and 997 and the box is something I keep coming back to.

On our 996 boxes, repair time is completely on the driver. Miss a bunch of shifts and box needs refreshing sooner. What we have seen with occasional shifting imperfections is at 35-45 hours a refresh on the box. Typically in the $4-6k range. And a major service every other time to $10-12K. IF 997 has a blipper or a DAMN GOOD DRIVER we see about similar costs. Of course on the 997 baby the shifter with no blipper and you will find yourself with a $20-25k bill....

Catastrophic failure of either 996 or 997 transmission could be just as expensive one another, however it seems more common/easier to achieve with the 997 sequential (again, only from what I have heard).
Function-First is a vendor on these forums. He supplies a kit which upgrades all of the internal components in the 996 shifter. It's predominantly designed for the street car which has a lot of plastic bushings (the kit replaces the plastic with steel items for less play and better durability). However, the cup shifter (which is the same design as the street shifter only with mostly steel bushings as opposed to plastic) also develops wear over time and the FF kit can be used to rebuild this when needed. If you have near new parts in your car, you wont need to worry about it for a while, but it's a great option for those who do as the cup shifter is NLA AFAIK.
