I bought a Techart rear spoiler in the UK for the 944 Cab and had it shipped to the US. It came with just some cheap screws for mounting it to the trunk lid. I drilled the holes and attached it with the seven screws that came with it. I wasn't thrilled with the screws and the strength of mounting fiberglass with just a few screws.
I kept thinking about finding a way to bolt it on for more but never got around to doing it.

One early Saturday morning I am on a very empty stretch of road so I decide to stretch its legs. At about 120 I hear a single strange thump from the back of the car. I didn't hear anything else and the car didn't seem to drive any different so I continued on home.

I got home and as I was getting out of the car I looked back to see a row of seven cheap screws sticking out of the trunk lid.


The lesson is don't do a high speed run with questionably mounted body parts.



I bought a replacement spoiler and this one arrived with several steel inserts bonded into the fiberglass and bolts to hold it on.

Here are couple pics taken a few weeks before the high speed run.
