I successfully run 295/40ZR20 tires ... No fitment issues whatsoever.

Having the main unit concealed is a great feature, especially if one gets interviewed often by Johnny-Law.

I use an Escort 8500 in my cars and I've noticed that when the unit is installed in the Cayenne, the sensitivity drops off. In both cars, I mount the detector on the front windshield, just above the dashboard.

On a side-note, I use a toll transponder for toll roads/bridge tolls. Inspecting the front windshield, I noticed that there is a factory film installed, and it has a gap (no film installed) along the rear view mirror location. If I place the transponder there, it works. The Homelink signal may be broadcasted at this location as well. Additionally, the transponder works in the Cayenne when the unit is placed (momentarily by hand) along the sun-roof glass.

The point I'm trying to make is that the factory film (tint) reduces (attenuates) the signal of the radar detectors. To have the greatest radar detector range/sensitivity, it is best to have the detector's receiving unit outside of the vehicle's interior.

My other car has ceramic-based film instead of metal-based film (yes, I installed film on the front windshield). I have no issues with signal attenuation with the ceramic-based film.

Check the current lineup of collapsible spares that are used with the current Cayenne Turbo (957). The 955 CTTS should have the 380 mm front rotors. Ruf's big brake kit (Brembo) should be 380 mm - not 405 mm. The 957 CTT uses the monster ATE calipers and rotors. Those should be 380 mm minimum.

Looks great! Any mods to the drive-train?

The blade for Porsche Keys is the same as with VW/Audis, and your local VW dealer can cut the blade for you usually for free. There are several vendors on eBay that sell replacement remotes for Porsche both new and used that are under $100. That just leaves getting the key authenticated with the cars security system, and some dealers will do that for free as well or charge less than $75 to do it.

+1 ... when I purchased my CTT, I purchased several key fob/remotes on eBay. I then got them programmed and key cut by my local Porsche dealership.

For the past two weeks, I was getting the same fault (Air Suspension Faulty - Workshop). I just brought my vehicle in for a 60K mile service and thanks to you guys, I was able to tell my local Porsche dealership "NO, I'll repair it myself. I read on RennTech.org how to repair the air suspension compressor." I'm off to the VW parts department ...

I think you may have something there.. I logged in "Porsche 911" and then in a seperate Google search page "Porsche Carrera". Results:

Porsche 911 8,290,000 Google Web Pages found

Porsche Carrera- 10,700,000 Google Webpages found

Strangely Porsche Carrera seems to be used more.. Who would have thought??

Well, sure Carrera is going to get more Google hits ... "Carrera" name/package was first used with/on the 356 way back when. Carrera is a sub-model name/package that has been used with many Porsche models to date. THE Carrera is of course the Carrera GT.

I've noticed if you tell someone that asks you "what kind of Porsche do you drive?" and you say a Carrera, they usually assume it is the 911 model. These people typically don't know Porsche vehicles at all. Now if they follow up the question with "oh, which Carrera model?", ding, ding, ding - we have a Motor Head winner, or at least a Porschephile.

From Wiki ...

Carrera is a trademarked name (Spanish for "race") exclusively used by Porsche for its models to honor the company's success in the Carrera Panamericana race.

The following vehicles have been called Carrera:

* Porsche 356

* Porsche 904

* Porsche 911

o Porsche 911 (1963-1989)

o Porsche 964 (1989-1993)

o Porsche 993 (1993-1998)

o Porsche 996 (1998-2004)

o Porsche 997 (2004-Present)

* Porsche 924

* Porsche Carrera GT

Can anyone give me a suggestion on cross drilled rotors for an 04 Cayenne Turbo? I hope I don't offend anyone, but I'm looking for someone that's installed a set with no issues/good experience. I know of companies that make them that I've used for other cars I've had. However, I'm looking for someone that's used then on a Cayenne. I've looked on E-Bay and see a few but am always a little nervous on using someone new with personal experience or recommendation.

Happy New Year to everyone! :renntech:

Well, throwing caution to the wind, I went with slotted rooters instead of cross-drilled.

I did this to reduce the risk of debris getting between the rotor and pad (as compared to cross-drilled). It is very rare to see 4-wheel / off-road vehicles with nothing but non-grooved, non-drilled rotors.

I purchased all of my rotors (StopTech SportStops) and pads (Hawk HPS) from Zeckhausen Racing. Hardware was purchased from Porsche.

I chose to cryo-treat the rotors and pads to extend life. I used CryoScience.com

You will need to have a specialty bit to remove the rear rotors. I purchased mine from Snap On. It is a 16 mm triple-square socket driver bit (Snap On Part Number: STSM16E).

Best of luck.

Rick -

Congrats on your new acquisition ... nice choice.

I'm really surprised that your vehicle did NOT come with Park Assist. A Cayenne Turbo S typically would have this system already installed, though it is an option (I believe). I'd check with your local Porsche dealership first what would it cost to install Park Assist versus installing the Wireless Laser Pro Park system.

I just ordered a set (front and rear) of Hawk HPS pads. I'm waiting for my rotors to show up, then I'll change the brakes. I'll report on the pads soon. I'm currently using OEM pads, hence, "dust generators".

For what it's worth, I purchased my rotors (StopTech SportStop) and pads (Hawk HPS) from Zeckhausen Racing.

When changing pads, Porsche recommends that new hardware is used: pad retaining bolt, pad sensors, and retaining clip.

Anyone know how to hook up the Bose Subwoofer to the Factory Bose System in a 2004 CTT?

Thanks for any help in advance!

- Andrew

Andrew - PM me with your e-mail for a general instruction on how to remove and install the Bose Subwoofer in the spare tire well. There is a connector to hookup to, but unfortunately I don't have the pin-out for the connector to the PCM unit. I'm assuming you are trying to connect to the PCM.

Norman

Moose - I believe in RFM's posts "prohibited" means "not necessary".

This may be "lost in translation", but I believe that the point/suggestion RFM is making is that if you are only changing the brake pads, don't remove the caliper from the spindle assembly. And I'm sure you know that if you are changing the rotor, then the removal of the caliper is necessary.

Great ... sounds like you got a plan. Best of luck, and be easy on your knuckles!

I believe I found the socket you'll need.

Snap-On P/N: #FELM10A

Description: Socket, Metric, Spline, Deep, #10, 10 mm Hex

Here's the link:

http://buy1.snapon.com/catalog/item.asp?P6...amp;dir=catalog

Thought of that one, but again it's 12-point and it's for a ~10mm head. the two heads on this caliper are maybe 13mm and 16mm and 10-point.

No, Moose, that is a 10-point spline head socket. Give your local Snap-On rep a call. You'll be good as new I'm sure.

And here's the link to the entire spline socket collection:

http://buy1.snapon.com/catalog/catalog2.as...re=snapon-store

I did a quick web search ... that bolt is a "Spline-Drive" head bolt. And you are correct, it is common in the Aerospace/Defense world.

Snap-On has an impact socket for a Spline-Drive ... http://buy1.snapon.com/catalog/item.asp?P6...amp;dir=catalog

Here's a website that sells the bolts - give them a call, they may be able to sell you tooling for this bolt.

http://www.fastdim.com/bolts_spline.html

The parts list (March 2008) calls the large bolt "hexagonal-head bolt M16 x 1.5 x 48".

Have you tried a hex socket on it?

That's a strange bolt head ... not a hexagonal head (12 point) for sure - as Moose described earlier, it is a 10 point or spline head.

Would this specialty socket work? It is from Snap-On.

http://buy1.snapon.com/catalog/item.asp?P6...amp;dir=catalog

No, they're male bolt head, and they have 10 splines instead of 12. i'll try get a pic later.

Oh, okay. Yes, a picture will help. The 955 (2003 - 2006 Cayenne) uses the XZN bit. I've seen bolts on high-end multi-piece wheels (HRE, Kinesis, etc.) use a multi-spline male cap.

The 2008 Cayenne Turbo brake calipers - are they manufactured by Ate? They are huge and must weigh a ton! Monsters.

Hmm... are you sure they aren't triple-square bolts?

http://en.wikipedia.org/wiki/Triple_Square_screws

I agree with Loren ... they are triple square bits, also known as XZN bits. Sure, Snap-On sells them, but can be found by others as well.

Here is a link to AutoDax.com that sells a XZN Bit Set for $28.97 plus S&H.

Good luck.

Anyone have any experience with snow chains on the Cayenne "S"? I was thinking of picking up a set for my 20" wheels but the cost is staggering - over $1,000 for a set of 4. I would like to know if anyone has used them and what opinions are. Also, any good sources for better pricing? Thanks.

I haven't put any snow chains on my Cayenne to date. For most conditions, All Season or Mud and Snow (M&S) tires without chains should be adequate for driving in the snow.

Take a look at this link about snow chains on a Cayenne.

Well, it was pilot error on my part - I had ALL of the CDs upside down in the magazine. A little embarrassing.

Sometimes, N-spec tires are not available for contemporary wheels of today. To address this, I examine the N-spec Tire "specs" and then look for tires with the same or better specs. I look at tread wear coefficient, maximum load, speed rating, etc.

I'm impressed with the performance of the Scorpion Zeros Asimmetricos - great value ... $275 per tire compared to $441 per tire of the Michelin Diamaris.

I haven't DE/AX the Cayenne yet, but based on the performance through the caynons (tight technical corners at times) I'm confident of the tire.

Have fun ... rotate often!

I also rotate AND balance my tires on 5K mile intervals. I'm running 295/30 22" Pirelli Scorpion Zeros ... 15K+ miles and they are wearing great. I drive highway, city streets and aggressive canyon carving rallies.

What tire are you using?
