  1. thanks for the feedback guys @Scott: you're right, I'm not quite driving at the levels of Schumacher. G-forces should be reasonable :D @Greig: Considering the weather-conditions over here in Belgium (quite often rain and cold), similar to Scotland I guess, Corsa's may be more appropriate, and indeed, in the price offers I got, they are 150 EUR cheaper for the set of 4.
  2. You should definitely get it checked out ! These cars are not supposed to consume oil at all. I can tell you that my '99 996 with close to 100.000 km on the counter does not consume a drip of oil, not even during track-days at Spa where we push really hard.
  3. Some people alert me that I should be worried about "oil starvation" due to pulling those high Gs with a wet sump? Is the difference in G-force between street tires and PSC or Corsa that big??? Clearly, my only aim would be to ensure adequate traction and me having fun on track-days. At the last one I attended with street tires, it was a stressful experience to feel the rubber melting away . Other than that I estimate to do not more than 3 or 4 track-days a year. For the remainder the car's is my daily driver.
  4. Thanks for the feedback clord. You're right - it's a compromise to be chosen but I have to consider that this car's mainly my daily driver as well. Upon looking into Tirerack technical recommendations for the PSC I found the following: Vehicle Wheel Alignment Recommendations Camber should be negative: Acceptable 1 degree negative Preferred 1.5 to 3 degrees negative (for most basically-stock or moderately-modified cars, the "sweet spot" is going to be in this range) Maximum 4 degrees negative Proceed carefully with camber adjustments. Too much camber means giving up efficiency in braking and accelerating. Achieving the right balance between cornering grip and straight-line grip (braking/accelerating) is key. For those enthusiasts who simply want the opportunity to explore their vehicles’ limits with higher levels of grip, but who don’t want to make serious modifications to achieve high negative camber values, Pilot Sport Cup will still operate effectively with more conservative factory settings for camber. Caster should be set at the vehicle’s most positive recommended setting. In most cases, toe should be set at the middle of the vehicle’s factory spec for each axle. However, depending on the competition situation (tight road course, more open, flowing road course, autocross, etc.) it is possible to materially affect the initial turn-in of the car and its stability in high-speed transitions through manipulation of the toe settings. Care must be taken because Pilot Sport Cup tires generate significant levels of lateral force even at very small slip angles; thus, large toe-out or toe-in settings can have big effects. In general, a good starting place is near zero toe (parallel) or the minimum value of the factory spec for toe-in at the front axle. At the rear axle, moderate toe-in (usually the minimum factory spec for toe-in) is not a bad place to start. I am also curious about the statement: Pilot Sport Cup will still operate effectively with more conservative factory settings for camber. I assume this means effective yet not 100% optimal and implying uneven wear of tires. Anyone know what is the factory camber setting on a '99 996 C2??? I don't have a clue what caster is about. I'll look it up in my Dutch-English dictionnary. :drive:
  5. I can't wait to go back on the track with my C2 in a few weeks. In preparing myself I am considering to mount racing tires on a dedicated track-rim set: either Michelin Pilot Sport Cup or Pirelli P Zero Corsas. By using those 'street-legal' racing tires, on, to and from the track, I aim not be restrained by the adherence and endurance limits by which my Conti SportContacts (and any road tire indeed I suppose) gave me a hard time on the track before. My C2 is not fitted with the optional sports suspension and some people advise to give the car some more 'negative camber' in order to take full use of Cup tires. Has anyone ever done this before? Any experiences to be shared would be welcome. :rolleyes: P.S. I know I would be better off with purchasing a GT3 straight away. In fact, this will probably be my next one and my dealer even proposed me a nice 2nd hand Clubsport but the bank account advises me to wait 1 or 2 more years.
  6. Apart from these sizes a critical thing to bear in mind is the Porsche N-rating of the tire you will purchase. Chances are that when you deviate from standard sizes you will not find the tire with the required Porsche N-rating.
  7. Having recently purchased a set of 8" and 10" Carrera Rims I schedule to fit them on my '99 C2 with tires in sizes 225 in front and 285 rear. My dealer confirmed me there's no problem whatsoever. I note also that in Porsches factory Tequipment brochures these rims are offered with those tire sizes for all 996 C2 and C4 Porsches from MY 98 till MY 04 :drive: On my 'old' Turbolook I rims I currently have Conti Sportcontact2 in sizes 225 in front and 265 rear. I intend to "finish them" on a trackday soon. Afterwards I will fit the Carrera Rims but I'm still not sure what tire brand to purchase <_< It should be the best compromise between everyday use and track-day usability. How do Conti, Michelin and Pirelli compare in that respect? Any experienced advise would be welcome :jump: .
  8. I have two Fabspeed mufflers on my 996C2. They sound great and are of a very decent build-quality. Unlike PSE they are in stainless-steel.
  9. It is no problem to use 8J x 18 for the front with offset 50. I did that on my '99 C2 by fitting Carrera 18" rims of the '01 MY. :thumbup:
  10. I agree with LVDell: For the 996 these rims may not be optimal at all. I have 18inch Turbolook I rims on my '99 996 C2 and they size Front: 7.5J*18 ET 50 Rear: 10J*18 ET 65 Boxster is a completely different car and the rim specs reflect this. It should not be any problem to find the appropriate sizes at good deal prizes. I recently bought myself on eBay a set of 18 inch Carrera rims w/ wintertires. They look and drive (because lighter and slightly wider in front) awesome. Since this is my 1st post I should also like to introduce myself. After becoming a carnut at birth, I'm a Porsche 911 owner since two years and completely addicted since then. I live and drive in Europe, Belgium and use the 911 daily as well as for leisure on track-days. I hope to spend many nice and interesting moments on RennTech and also contribute by sharing any experiences where possible. ;) This is my car:
