I purchaced my first 911 in Novemeber 02, a 993 C4S with 25k miles from an OPD in Guilford. I have covered around 1500miles since. This year I decided to upgrade it slightly. A new sports exhaust system with 100cell cats, a mild tweak of the engine & some fully adjustable Suspension. I chose Tech 9 based in hale as they use Techart products which are TUV approved & as a proffesional race team they know a thing or two about getting the most from 911's.
During the upgrade process a number of issues came to light. The 4 wheel drive system was infact not working correctly infact it transpires that thedrive shaft from back to front is broken, the Diff plates on the rear diff were completely worn & to top it all my rear wheels had at some stage recieved enough force to buckle them out of true & are unbalanceable. The fact that I had not noticed any of this is testomony to the incredible dynamics of the car. The original suspension being slightly softer than the new had smoothed out the vibration coming from the rear wheels & the fact that I am a new porsche driver has probably saved me from overcooking it throuhg the twisty bits with out the 4 wheel drive there to save me.
You might assume, as I did that all of these things are checked on the 74 point check that OPD carry out on their cars before selling them. This is not the case infact I have been informed that they dont check anything to do with the 4 wheel dive system routinely on 993's & they would not pick up problams with wheels unless they had to take them off to replace tyres etc.
The moral of the story is trust no one! make sure if you are contemplating purchacing one of these fabulous cars that you get them to check the 4 wheel drive system out & balance the wheels.
As you might expect I am in "discussion" with my supplying dealer to rectify these problems. Iwill let you know how I get on.
