Those with Centre Lock wheels will be aware you need to tighten the Centre Lock bolts to a torque of 600 nm and torque wrenches capable of this kind of grunt are few, far between - and expensive! 
However, Auto 4 in Solihull currently have a special offer on Norbar Torque Wrenches this week and can supply a 300 - 1,000 nm unit for £280. The unit comes with a calibration certificate (+/- 4%), a handy folding storage case and free shipping.
If you fancy one you can contact Paris Dineen 01235 776636. The offer is open until 5pm this Friday 17th September.
BTW - It's ¾" drive, so it will fit directly into your Porsche supplied socket. You also get a 1" adapter as part of the offer and this would allow for some really serious torqueing!

Clive
