  1. Re: High Pitched Brake Squealing on 987s To end this fuss, I ended up paying for my pads HKD 2780 rear pads and I had requested for my old pads to be extended to me for double checking at another brake specialist if need be. So far the car doesn't squeak. There's no vibration so it is unlikely that the brake disc is warped and the caliper seldom gives me problem so squeaking usually means that the pads are worn (but unlikely on mine at 7000km) but in any case, I had gotten myself new pads. Also put in 5 mm spacer set the difference is minimal. I wish they had the old 986 set on simply rear 14 mm but now I have 4 sets of 5 mm. Loren, I repeatedly asked for an explanation and the answer was this: Selected vehicles of Porsche would exemplify squeaky noises due to the materials of these racing stock brakes and we wrote to the factory and they said it was absolutely normal and safe. Well, what can I say right? Let's hope it doesn't return.
  2. Thanks. MY VIN wasn't on the TSB list cos I live in HK. I am through with this squeeking and had decided to replace the rear pads at my own cost but this is certainly a bit out of the ordinary to change pads at 7000 km.
  3. Even with the rusting on top and bottom of the rear rotor (the 2 strips of rust that were absent on the front rotor?) Let me check my vin I have a HK vehicle.
  4. Front disc. No brake squealing at all. Loren for sure you are definitely knowledgeable enough to tell me. The dealer left the decision up to me and of course changing pads at 7000 km is at my cost and I wonder how long it would take for the pads to wear down so even contact can be achieved again.
  5. Rear disc. Both discs in same condtions.
  6. My car's rear brakes squeaked consistently and the service centre sanded away the edges in an attempt to eliminate the squealing. They sanded away the top and bottom edges of my brake pads leaving the middle in tact. Visually it is not nice as I checked out other 996 and the discs have no such edge rusting. I worry that if I don't change the pads, the rust will keep building up just like if you wash your car without driving it for a prolonged period that the rust would eat into the disc/rotor. Maybe I should consider changing the pads just to be sure. I know any rotor/disc will rust even with hosing but usually the rust will be taken care of by application of the brake a few times. However, on my rear rotors, now there are two distinct strips showing rust top and bottom due to the sanding away. Advisor said the only way to get rid of it is by natural wearing till the pads are even again or I have to change the brake pads. Should I be concerned? I mean visually it's not that nice but long term wise? I wouldn't mind changing pads but at 7000 km is a bit early. The advisor said on the TSBs, one of the solutions was sanding away the edges another being changed pads. However, he assured me that safety is not of a concern. It could potentially also be caused my the city driving condition of HK and the "soft braking" habits of mine. I doubt that it had anything to do with bedding in the brakes because I believe that these stock brakes aren't racing brakes and they should be intuitive enough to be bed in slowly by any everyday driver. Visually, it's really not going to go away not for a while but I worry the rust would build up to a degree that it hardens and get burnt into the disc.
  7. My dealer said a TSB was issued on selected vehicles having high pitched brake squealing when brake pads were applied softly or progressively, can someone shed some light on this TSB? Anyone experiencing this problem?
  8. Just found this: here are some times around Hockenheim track by German Sport Auto mag : Mercedes SLK55AMG 1.17,1min Porsche Boxster(240hp,PASM,18") 1.17,4min Porsche Cayman S(295hp,PASM,18")1.15,5min 1:15.7 --- 123.646 km/h - Porsche Boxster S (2005), 280hp/1406kg (sport auto 12/04)
  9. this is rare but a stock black boxster S and the guy looks like he was trying hard to overtake him but he couldn't although he had 75 hp over him... making him around the 350 range... maybe it's an M3? I wonder how a M3 would run against a 987 s but M3 has the SMG which is touted to be one of the best sequential pioneers. Alternatively, another car which I would definitely be interested to watch a video on chasing around a boxster s or other way around a 987s chasing around a M3 and or SLK 55 AMG. The 55 AMG for sure is like way ahead of a 987s with a 5.5 L V8 churning out 300+ hp but that was what I drove for a while before. I don't think I will ever miss it but the 55 AMG still feels very much like a softie but it can definitely win in a drag race but running around the hills or curves, I don't think it will have too much of an advantage over the 987s. There was a video comparison made by Top Gear between boxster s and SLK 55 but the 987s definitely handles better. I am sure 987s would have no problem doing a few rounds on the R171 slk 350 but it would be fun to watch it head to head against some muscle cars like M3 or 55 AMG. What do you guys think?
  10. IMHO - I think you have a few more model years before you need worry As the Boxster is the lowest cost Porsche sold, it is also at the bottom of the list for features. Certain features are held back just to preserve a gap between the Boxster and Carrera/911. A simple example would be no glove box in the Boster until 2004, even though the same dash in the 996 had a glove box. I suggest it is likely to be several years before the new high tech transmission technology "trickles down" to the Boxster. In a likely scenario - First the transmission goes into the TT/GT3/GT2 cars, then into the Carrera, then into the Cayenne, Cayman and the (as yet to be named) 4 door Porsche Sedan, then the second generation of dual clutch transmission hits TT/GT3/GT2, THEN we see the first generation new transmission in the Boxster . I may be pessimistic here, as Ceramic brakes moved down the food chain very quickly. This is almost certainly due to the fact that Ceramic Brakes are a seperately billed high cost item. If the paddle shifted transmission is marketed like ceramic brakes , you may see it travel down the food chain to the Boxster in 2-4 years. Looks like it and the 987 isn't gonna get it maybe in the next 24 months and I think maybe in 36 months for sure. Most technologies (new ones) go to the high end models first to keep the segmentation clear between entry level models and to protect owners paying premiums. The only concern (it is going to come but when is the question) is that tiptronic S wouldn't be supported anymore. The real question is whether or not tiptronic S would go in parallel with PDK just like the PCCB. Normal brakes are used but PCCB is a high cost item that you can add on. For e.g., all normal 987 or 997 would have manual as standard and tiptronic S as option but you will have to pay a ton more like the PCCB to get the PDK technology. This makes perfect sense for P to cash in on a new technology like that and very hard to imagine P to completely replace tiptronic with such a newly developed and high cost item. Any normal user wanting an automatic without too much worry on shifting lag times can simply take the good o tiptronic s and those who want something simlar to DSG that shifts faster with less lag time could pay more. This would look most natural as a market segmentation strategy to me.
  11. Anyone has any input on this front? I didn't wait at all and ordered my 987s tiptronic and now most of the news is out on the 997TT except the deployment of PDK/DSG. P is really keeping that under the lid and seal so no news at all. I know all 987, 997 2006 MY will get tiptronic S only and no PDK at all. However, it will definitely be a bummer to find that I just ordered the 987s in tiptronic to be the last production year of a new model with tiptronic S cos it is highly likely that all MY 2007 cars will start to get PDK. Does anyone know any news on the PDK deployment if at all?
  12. A friend of mine who lived in Edinburgh said because of the rather rainy and moist weather in Scotland, cars tend to rust more easily. A friend of mine shared his maintenance tip with me and said that cars in general would be better off to avoid as much water as possible. Hence he said that the better way to keep cars would be to use wet clothes to wipe your car on a daily basis and spray hose it maybe once a week. He also said to never spray directly at the rims like those car washing houses do but on the tyres more because spraying directly at the rims would mean spraying too much water on the brake discs and it wouldn't be good for the car either. The weather in HK is defintely great for keeping exotic cars like Porsche. We never snow in the first place so salt and dirt and mud aren't too much of a problem. Just want some inputs on maintenance and care. In general, does using a hose to spray the RIMS of a car on a daily basis to clean the dirt tend to cause premature rusting on the rotor and brake disc? The disc always rust to a certain degree and I believe that washing on a daily basis is not a problem as long as you drive it after instead of letting it dry naturally. I believe that from a maintenance POV, it is always better to wash the car in the morning and then drive it right away so the heat can evaporate the water instead of letting it stick with the axles and rotational system overnight. Any input? Intuitively, the more frequent you wash the car, the more chance for you to cause premature rusting?
  13. Any simple break-in procedure on a 987 stock tip S? Some people actually said modern days cars are so well made that there is little to be worried about on break in. Just drive it but I doubt it. Inputs?
  14. How's the breaking in coming along and what are you doing now on break-in procedure. I am still thinking whether I should get it in Silver Black or Black on Black. Though I like Black on Terracotta but that option ain't worth it in my mind.
