  1. For the sake of closure and thanks for the advice I wanted to follow up, I intended to return the wheels to 18" but couldn't find what we wanted in a timely manner, a decent looking black 5 spoke. We were looking at the Victor Baden's but couldn't find a full set in 18" or 19" so we opted for staying with 19" rims and chose the Bridgestone Potenza S04 pole position 235/35 19Y tires up front and 305/30 19Y's in the back on Roderick 19" x 11" RW5 's in matte black (about as tight of a fit with this wheel as one could get without spacers). After a month on the car I have to say we are really ple
  2. I've never known an engineer to be so cavalier about precision, In the spirit of the forum it would have been helpful if you'd just answered the question .....
  3. The website I pasted in did not get into the above post, is that against forum rules to paste in a link to another website for data reference? the 804.3 & 808.2 rev/miles referenced were for the Porsche summer tires listed in my manual.
  4. Hi guys thanks for all of the posts, my manual lists the summer tire sizes as 225/40 ZR 18 front and 295/30 ZR 18 rear, I found this website that was helpful https://tiresize.com/calculator%C2'> (click on the tire size calculator for rev/mile info) /, Dave is your comment related to the difference in revolutions per mile ? From that web site the difference 804.3 rev/mile front to 808.2 rev/mile rear is that the impact that you are referencing for fluid shear ? Is that the impact in % difference that xmaciek82x is referencing ? Should I try to keep those front to back numbers as close t
  5. Thanks for your response, Buying the car second hand, I don't know all the mods that have been done to the car as far a larger brakes etc, I'm satisfied with the overall performance and don't plan on racing. So based on your note, I am correct that the 235/40 19" up front and 295/30 19" rear will work, correct ? The 19" rim size is only referring to the rim size the tire will fit, I don't have to buy lower profile tires to compensate for larger rims. I just want to be certain before I put an order in for these tires. Thanks Glenn
  6. Hi, I have a 2004 996 TT. I purchased the car with 19" rims on it and I'm not sure what to do about replacement tires. The front tires that came on it are Michelin 235/35 ZR 19, the rear tires are Azenus 275/30/ ZR 19. With the difference between the stock recommended and the mismatch on the tires now, I'm not sure if any thought was given to the correct sizing. I have to replace the fronts, the rears are new. I'm more inclined to replace all four. Does anyone have any insight as to what the best size selection would be for this ? It's a summer car that only sees rain when the unexp
  7. Yes there are two hydraulic Rams that are fed from the pump housed in the rear lid under the fan housing. The pump like any hydraulic system pumps the fluid through the bottom of the ram, to extend the piston and the top or reversing flow to retract it. Have you nticed any fluid leaking usually residing in the caps on the bottom of the rams. I would check to see if the Pistons are raising Uniformly, same speed same pace, any binding also when the pistons are extended are there any scratches or gunk on them that would impede free movement My system was almost bone dry with residue in the c
  8. Does it function properly otherwise ? I.e. Go up on its own when you hit the proper speed and retract when you slow down? Raise and lower when you press the button? If that's the case it's likely that it's one of the micro switches found on the passenger side ram under the snap on plastic cover. My spoiler wouldn't function at all. The fluid was leaking and really low, i removed it and purged and refilled the fluids but I bunged up the top micro switch and now I get a warning when it raises at speed I just haven't had the time to replace it. They are very small a very easily bent so be c
  9. Thanks JFP, I appreciate the encouragement, I'm confident that my guy can find an alternative solution besides replacing an otherwise flawless tranny. I'll update the thread when the repair is completed. Best regards Glenn
  10. Sorry to revive this old thread but it explains the situation that I'm having with my '04 996 TT and it's going in the shop on Monday and I have been told the same story. My independent wrench feels that it is repairable even though Porsche stated there was no gasket for that part. Has anyone else had any updates on this issue ? Has a new gasket hit the market or is a fabricated gasket a solution to this. Any input would be appreciated ! Thanks Glenn
  11. Hi, I'm trying to remove my PCM 2 unit and have found posts that reference the hex wrench and detents that need to be pivoted and then I saw this diagram that Loren posted a while back. I have pivoted the detents, actually pivoted them right out of the radio so I know they are not providing resistance. This is the first time that I have seen reference to a spring clip that needs to be pressed and it seems more in line with what I am experiencing. I have a 996 TT, am I at the stage now where I just need to squeeze the tabs (that I do see) and pull the unit out ? Pressing in the tabs
  12. Hi , I have a PCM 2.0 is there a separate code for the radio and one for the nav ? It's my understanding that with this radio I have to go to the dealer to get this code retrieved. When I bought the car they had put in a new battery so I'm wondering if they only had the code for the radio as it works fine but the nav can't locate any satellites. Thanks Glenn
  13. Hi, sorry for the late response, I just saw this. I didn't know there was a two battery option ? Would it be located near the main in the front compartment ?
