Hi,

I've got a 2002 986 with too much negative camber on the right rear. I found this out after removing the rear wheel to do some thorough cleaning. The inner portion of the tire was down to the threads and belt! I replaced the rear tires with Pilot Sport PS2s Thursday, but can't get in to my Porsche shop for an alignment before next week. Problem is...autoX on Saturday. I don't want to miss it, but I don't want to chew up my PS2s.

Any help would be greatly appreciated.

Thanks,

E

PS the only tools I have are a pair of pliers, toenail clippers and a butter knife.

I wouldn't mess with them unless you have a magnetic level and the proper plates to also adjust toe. Changing the camber on the 986 rear will also effect you toe. I would try to find a shop in town or push the dealer to get you on the rack before you abuse the new tires at an autocross.

I just had all 4 replaced and asked for the Michelin Pilot Sport Rib. When I got home I discovered the front tires were sport ribs and the rear were pilot SX mxx3 tires. I think the ribs are N2 and the SX are N0. The dealer claims they made a mistake, but they are all good tires. The dealer said he would swap them out. Should I care enough to go back and change the rears out to sport Ribs?

Yes, you should care and you should get the rears swapped out with the Sport Ribs. The main reason is to maintain a consistant compound/construction between the front and rear. That's why Porsche says specifically to not mix N types front to rear. i.e. N1's on the front and N0's on the rear are a big no no and that's within the same tire model. When you cross model types it's even more of an issue as N0 in one type and N0 in another are still not compatible.

Get them all the same, especially for the money you probably spent doing tires at the dealer.

The part numbers are:

Throttle: 955 423 211 10

Brake: 955 423 212 10

You can get the set along with a nice matching dead pedal here: http://www.eagleday.com/cayenne1.html

Here's a chart showing the Back Spacing (BS) vs. Front Spacing (FS) for various widths and offset (ET)

W ET BS FS

9 60 6.86 2.14 <<--- = Stock 20x9

9 43 6.19 2.81 <<--- = Stock 20x9 w/17mm spacer

10 50 6.97 3.03 <<--- = TSW 20x10

9.5 52 6.80 2.70 <<--- = OZ 20x9.5

As you can see the TSW's actually stick out farther than the stock wheels with the 17mm spacer (3.03 vs. 2.81)

Loren,

That's great!

Do they give specifics for the S and Turbo variants of the logo?

I know there are templates in the 911 and Boxster sections for the installation position of the rear logos but I can't find one for the Cayenne. My dealer says they eyeball it, I find it hard to believe that Porsche hasn't documented the logo placement in detail.

Does anyone have that information?

Thanks.

Loren,

I saw those after I made my post. Thanks for keeping me honest.

Loren:

Do you have the published specs for the CT ? toe, caster, camber ect. ? Thanks :lightbulb:
