  1. I think what's especially troubling is that neither Porsche nor Bose can say what the adjustment of the surround setting does! I've corresponded and spoken with Bose and come up blank. Had a small recording studio and band a while back (ok, quite a while back) so I think I know a little about getting good sound - and this is just ok. Wife was looking at that new little Volvo before she bought an RX-8 and it had the controls to make it sound nothing short of amazing. FM radio stations all step on their signal hard, that is, modify it via compression/expanders, equalizers, and sometimes other processing so I wouldn't expect them to sound good from station to station. PM me and I'll send along my settings to try out if you are interested. My music is usually Metal or Hard Rock.
  2. Looking for a cheaper and easier way to have a set of track/DE tires for my 2006 997 C4S. Would like to get a second set of wheels, 18", to fit the rubber on, either street or DOT track tires. Right now the car has Factory 19" Carrera Classic wheels. The manual says to fit the with: 235/35 8.5J with 55mm rim offset fronts; and 305/30 11.5J with 67 mm rim offset rears. When I bought the car last year there were 235/35 front tires, 305/30 rear tires and I've been replacing with same. The front wheels have on either side of the air nozzle 8 and 57, the rears have 11 and 51. The car was ordered with 5mm spacers as an option. Just looking at the numbers above I would hazard a guess that the fronts are 8" and not 8.5" and have 2 mm more of an offset. The rears are 11" and not 11.5" as recommended in the manual with the 5 mm spacers used there for 56 mm offset instead of the 67 mm offset. Am I correct? Is there a wheel fitment guide somewhere that is the equivalent of "how to read a sidewall of a tire" so I can decipher these numbers and get a set of 18" wheels that fit and won't adversely affect the handling?
  3. At the end of the first DE of the year in my new-to-me 06 C4S Ruf RK my brakes were not effective. One of the mods I made was to have the GT3 ducts installed. They are larger yet you will probably scrape the deflector immediately below the front bumper or the air deflectors in front of the front wheels before scraping the brake ducts. FWIW the other mods were Pagid Blues, which I change out with Factory pads when not at DE, and Motul 600 brake fluid. No fading at all now.
  4. Not even close Paulspeed. The Nav system in all wheel drive 911s is installed vertically against the trunk well face directly below the compartment. Maybe you should go back to your moonshine.
  5. There is a small storage compartment in the 997 all wheel drive luggage compartment above the Nav DVD, or the front left facing side of the trunk as one looks into it from the front of the car. This must be the 00's version of the old Carrera smuggler's box, I guess. It's where I put a small bungee cord, a micro fiber cloth, and a tube of sun screen. Searching the MY06 manual on the term 'DVD' I came across the warning "Risk of Damage. Do not store any objects behind the access cover A." , which is what I thought was this small storage compartment. Any one have an idea why putting something in there would cause damage? Can someone help me to understand why Porsche would have what seems like a storage cubby in the trunk with no warning stickers not to use it AND a front lid to open and close on it? Seems odd.
  6. Ruf Auto Centre put in Motul brake fluid, the GT3 brake air ducts, and Pagid Blues. Motul is less expensive than Castrol SRF and thought to be close in performance. Ducts had to be replaced anyway. Porsche Sport Pads are not available for the 997S. Little squeaky at the end of a slow stop in traffic - nothing that really bothers me. Next DE is end of April at Motorsports Ranch. Will add to the thread with my observations after then. Thanks to all of you for your comments and suggestions. BTW I don't plan on thrashing this car on a monthly basis at the track which is why I've gone with a compromised solution. If I really get the bug it's likely another Porsche will have to join the family.
  7. Have 2006 C4S Cab w/Ruf Kompressor. Go is good, whoa needs help. If I string together some really good laps I lose braking until the final inch of travel and then it's not at full stopping capability. Searched for brake related upgrades on this forum and would like to see if I can solicit feedback on experience with: FLUID - MUST DO COMPLETE FLUSH AND REFILL GS610 Castrol SRF Any real difference? DUCTS larger brake ducts Will either Turbo brake ducts or GT3 brake duct spoilers fit a 997 S? One of them needs to be replaced, ok refitted, due to some unscheduled under body work from taking a previously uncharted path on & off the track so I'm doing this anyway. "I just found a story that 997 GT-3 brake ducts fit on 997S cars with no modifications. They cost $30 from Suncoast. They also do not hang as low as other racing ducts." Rubbing problems on street/driveways? This is in Texas so the ducts are really moving already hot ambient air off the track surface over really hot brakes. PADS upgrade street to track? I will never do race. Blue race pads allegedly half street/half track. Who makes these? Any recommendations on pads that still work well in daily use however bring the car's speed down faster would be great. LINES Stainless braided brake lines have been mentioned. Seems like overkill with new fluid, ducts, and pads. Thanks in advance.
  8. Looks like the culprit was the power steering system. Funny how it manifests itself early in what seemed to be a transmission related problem. It appears that with slight loss of power steering fluid one gets a howl from the back when in gear under no or light load which progresses to the front of the firewall as more fluid is lost. Only when there is an appreciable loss of fluid does one get the characteristic sound of a power steering system issue when just turning the wheel. When the Ruf R Kompressor is installed the Factory power steering line from the engine to the steering rack is modified to accommodate the new manifold plumbing. Ruf Centre in Addison, TX fixed it at no charge. :clapping: Lucky me, as the local Porsche dealer wouldn't touch it after identifying the issue.
  9. The SC only is supposed to void the engine warranty. Clutch, 4 wheel system, and other drive train components are to be covered. We'll see.
  10. Searched for over a day here and at Rennlist w/o luck so I thought I'd post. Have a 2006 Carrera 4S Cabriolet with a Ruf R Kompressor, PSE, 6 speed with short shift kit. In the past week I've had what appears to be a transmission problem get worse quickly. It started with a slight howl or winding down of the engine, like a jet airplane shutting down it's engines, whenever I left the clutch in on that last 500-1000 rpms to a little under 2000 rpms slowing down for stop signs and traffic signals. Then it began when starting up in 1st gear from a stop. Drove yesterday and all seemed OK after the first block or two - kept top down thinking I'd hear more. Then last night on the ride home from going out with my wife I noticed the howl in forward gears and an added noise that seemed to come from just in front of the firewall. Top was up/closed. Today prior to backing out of the garage that all I had to do was put the car into reverse keeping the clutch in to cause the howl in back (parking break on, not moving) or barely start to engage the clutch in first. Sound did not happen with clutch was in and first gear engaged at idle. No howl reving engine in neutral. Top was up/closed for all in this paragraph. This would seem to eliminate the supercharger as it doesn't come on until engine speed exceeds about 1500 rpms. No blunt force trauma, always warm it up to operating temp before going over 3300 rpms (most around town driving is done 2200-3300 rpms), and rarely exceed 5000 rpms because the opportunity on public roads to go that fast in a Ruf R Kompressor is really not available. About a few weeks ago I noticed some oil on the rear passenger side garage floor. Up until a few years ago I had a 1984 Euro 911 that leaked a lot of oil however I though these new models with their integrated dry sump wouldn't leak. Yea, there is also a creaking from the left rear that happens when putting on the brakes to stop from a slow (<5 mph) roll or going down an incline slowly - like into my driveway. Have an appointment with the dealer on Tuesday morning. I'm thinking the two sounds are unrelated, however the howling from the engine bay and drive train sounds serious. No effect is felt driving the beast. Has anyone seen or heard of the root cause for the drive train howling? Thank you in advance for any replies.
