Default 993 Rear Spoiler Adjustment

I was cleaning up the car and I noticed that there are some wear marks where the rear spoiler meets the engine lid. Are there any adjustments because it seemd that it is closing too tightly and thus the wear?

I am curious to see if anyone else has this problem. It is not often that you even notice it because the spoiler is normally on auto mode.

Mine has it too. I don't know if there is an adjustment to be made or not. But... ...you are not alone.

Me too - I was going to make the exact same post. In my case wear is turning to rust, so I am keen to find a solution.

I don't think there is an adjustment, but you may want to make sure that you have all your round rubber cushions in place and that there are not worn out. These fall out easily (ask me ..I know) and with age and heat they may have been compressed or too soft. If these rubber pieces are missing or colapsed, you'll get the friction you are describing.

Also, after you replace thos rubber feet, you could place some 3M tape on the friction points. This will prevent the paint from being removed and rust to develop.

Good advice. Mine are all there. Do those rubber cushions have a part number, or are they non OEM - where can you buy them ? Or is it possible to just increase the height in some way without replacing ?

Part #: 999 703 449 40







Upon second look, I think this is the rubber part you'll need.
I don't know its part number....
Maybe someone can help

Cabrio's (Sergio's) suggestion is a good one. I think everyone has the paint rub marks to one extent or another. Make sure all the rubber bits and pieces are in place. I added pieces of "chafe tape" made by 3M to the wear areas. It is a 1/2" clear teflon film tape that is made for this purpose, used in different aviation applications. If anyone need some of this, PM me and I can put some on little spools and send it out.

Problems created by contact between the spoiler and the deck lid can be alleviated by adding or removing shims--or what are referred to as "liners" in the 993 Workshop Manual: "the distance between the rear spoiler and rear cover can be adjusted by fitting liners (up to 4 per side) between the [two spoiler] mounting plates and the rear cover." See Volume 5, Body, 66-1 through 66-7 of the Workshop Manual.

On two 993s, I made the corrective adjustment by removing liners, and in each case the wear--the scuffing of the paint--between the spoiler and the deck lid was stopped.

I jus checked, all my rubber stops are in place. the "liners" sound interesting and seems to be the corrective action. Any part #'s or pictures?

Has the car been in an accident? or have you had work done to your body panels? These "liners" are usually used at the factory to align the lid to the body or if the car was involved in an accident and the fit is no longer there.

Having to buy additional shims or "liners" and unmount/remount the lid to correct an issue with worn out rubber stops seems to much work for when there is an easier fix.

You'll find the liners on unmolested, accident-free 993s; they are what factory technicians use to establish a suitable distance between the spoiler and the deck lid. They are quite easy to remove.

Please please advise where to look for these liners - I can't spot them.

there should be micro switch on the left side under the wing which stops wing when it's running up or down. You can adjust this micro switch from "limiting screw".
