Less brakes, more gas!

You need to buy a little spec book. Reprints are available from Pelican (I think) and Porsche. Has all the torque specs in there as well as measurement and wear specs.

The motor and trans mount bolts are 58 ft-lb for the large M14 bolts. Anti seize highly recommended here. The smaller M8 bolts for the mounts themselves (mounting them to the rear chassis and trans crossmember) is the typical 18 ft-lb dry
The top of the front shock depends on your shock. If it's a standard Bilstein or Boge, it is also rather high at 58 ft-lb dry I believe Bottom of rear shock is 92 ft-lb if you've got aluminum trailing arms. Not sure about the steel trailing arm spec. Anti seize is acceptable/recommended here. Front rotor onto hub is M8 torque spec = 18 ft-lb dry Front caliper mounts are 52 ft-lb I believe for original iron calipers, anti seize recommended. Rear calipers cannot be effectively torqued, so simply snug them down with a bit of grunt from your 19mm box end wrench Going by memory (I check this stuff all the time on my racecar) I am confident in all of the above except the front shock and front caliper, because mine on my racecar are no longer original parts- I have Bilstein coilovers and 993-adapted calipers in front now. I will confirm the values later on, if no one else responds before I get home. That said, I wholeheartedly agree that a Porsche spec book or the Bentley manual are a must to have some good torque spec information handy.
