So i am tearing into my 01 996 turbo to install the items below and was curious if their is anything else I should tackle? Do the lower trailings arms fail often? Should I plan to replace those too?

997 GT3cup 8 plate LSD
GT2/3/cup front spindles
gT3cup sachs shocks F&R
Monoball strut mounts F&R
Solid subframe bushings
Torque solutions Tranny mounts
Gt3cup control arms front and rear
Solid caster pucks F&R
Remove front Diff(already disconnected)
Pin coolant fittings
Sachs stage 2 clutch
RS Single mass flywheel
Clutch actuator conversion

 

are you dropping the motor? if you are i would suggest welding the fittings instead of pinning. pinning only keeps them from blowing out but not from leaking. welding solves both. also if the motor is out replace the water pump as well. i had mine out and didnt do it w/p lasted another week then leaked like a sieve

 

With all that I would add cup cables.

 

I think most might suggest going through and replacing lots of the vac lines (zip tying them also) while in there.

 

The trailing (thrust) arms are cheap. You will likely find that they have developed a small amount of play at the inner joint. I'd change them.

There is no need to install solid caster pucks F/R if you are installing Cup LCAs as they already have them.

I'd swap in the 7GT3RS aluminum under drive pulley to reduce the wear and tear on your ps pump and other rotating components.

Are you using some type of spacers f/r for the short cup shocks? Curious how the shocks will work out in a street car with their extremely limited travel. 86/105 is Cup height based on 25.5/26.9" tall tires. You can't even turn the steering wheel much as the front tires will rub the fenders. Looking forward to the results.

 

I have the RS pulley going in. Forgot to add to list.

The sachs front shocks are only .5" shorter than my front H&R street coils. No spacer needed. I have a 1" spacer for the rear. I am not sure the length difference on the rear sachs shocks. If I can accomplish GT3 or a hair lower I will be happy. The key will be running the proper length bump stops.
