Do The Spoiler Mod and have it on manual only, like I did.

Now, the only time it goes up is on the freeway when I put it up.

Went from a bazillion times up-and-down around town for no reason everytime I drove the car, to about a half-a-dozen times a year.

And The Spoiler Mod was free and took 10 min

Same here. Replaced mine and it was broken a year later. I always use the manual override to keep the spoiler from going up and down but even still, I only got a year out of the new one.

Great mod and easy- did it too!!

I've done the spoiler mod and only deploy it manually when I think about it at higher speeds (around 70 mph). I'm still not clear if the spoiler's main purpose is for aerodynamic improvement at higher speeds, or for improved cooling, or both. And if the wall is broken, does it matter a little or a lot? I'm not convinced I need to replace my broken wall, since I seldom deploy the spoiler, and seldom drive in air temperatures above 80 degrees. But if I'm wrong, I'll replace the wall.

The spoiler's purpose is for aero.

The $10 option is to use Gorilla Tape.

Robin Sun monitored IAT with the spoiler up and down: https://rennlist.com/forums/993-foru...sequences.html

see post 14.

since the wall deflects air into the intake, I would think the wall or lack of it has an affect on IAT.

Thanks for the info. There is a gap of about 1.5" between the top of my curtain and the deck lid, so I doubt any tape would help much on mine. I don't drive above 80 too often, live in a temperate climate, and have the bottom engine cover removed on my car, so don't expect any issues. I will likely replace the curtain next winter while doing other misc repairs to the car.

I always thought the ultimate fix would be some silicon sheeting fixed to the spoiler wall remnants, I haven't studied it closely though so no idea if that would really work.

I have the Ruf spoiler module...raises at 80mph, lowers at 40mph. Still on original spoiler wall. If practical for you, you might consider opening he deck lid after you drive, to keep the heat from the engine from soaking up into the plastic wall. Not sure if that helps, but mine is in perfect condition after 19 years.

- I recall Paul Frere's book stating that the 993 retractable spoiler reduced both coefficient of drag as well as lift. Not as effective at either as the fixed wings of the 993TT, the earlier Carrera, or the 930, but still effective at high speed, nevertheless.

- The spoiler wall, however, was designed for directing some of the airflow that courses over the top of the car into the engine bay (aided by the negative pressure created by the engine fan). If the spoiler wall is separated, then air presumably passes past the wall out the rear as opposed to going down into the engine bay.

- OK, so that's the party line. Whether a torn spoiler wall actually translates to compromised cooling in our real world of commuter use and occasional fun runs is undetermined. Fix it if you have time, have an itch for a project, or are just A-Rententive about these things. But I seriously doubt a spoiler wall that remains torn is anything more than a mental irritant ...and one that is easily ignored given its location

The WORST kind of irritant for me

On hot days with the air conditioner running I put the spoiler up and it helps cool the motor. Definitely drops the temp at highway speeds
