Came across a strategically placed boulder the other day. Dark country lane. It was in a sharp turn. Cracked engine under tray. Thankfully no damage to oil pan or anything else. Tray took the sacrifice.

Would like to replace it with a metal one.
Cannot seem to find any online. Keep seeing Audi ones though!

It may be worth trying to find a sheet metal fabricator and taking your undertray to show them to see if they can make you one, it's amazing what they can do

That crossed my mind. My uncle used to work for a steel factory but due to his health he no longer takes on private work. Might have to ask my FIL. He's a CAD designer for Aston Martin. Whether he is willing to help who knows. Guy is a piece of work.

Don’t forget that if you’re going to fit a steel or aluminium under tray it will need beefed up fixings too. You’ll also need to remember that any hit to the metal under tray will be transferred to it mounts, which is mainly plastic at the front.

Other thing to try is a classic car restorer. These guys from experience ( Car SOS workshop) can make up body panels etc so I don’t presume a fairly simple piece like an under tray shouldn’t cause them too many problems.

Wound be at a price however.

A thin piece of alloy may offer no more protection than the standard plastic undertray , increasing the material thickness to get more protection will considerably add to the weight stressing the mounts and you dont want the metal coming off and getting stuck under the car whilst travelling.

I would just replace it with a standard tray and spend the savings on a pair of glasses and better headlight bulbs .

What about the BMW solution? The M cars have an aluminium under shield. Whilst they also have a different aluminium subframe, the M235i racing shares the steel subframe, and they fit the same aluminium tray to it. Most likely you'd need to drill and rivnut the subframe.

In the days of my E30 325i M sport when they didn't have undertrays I sucessfully managed to crack 2 sumps simply due to the low ground clearance and some undulating ground.

In the end fitted an M3 sump guard, which actually looked like a load of ski's on a frame, downside was it used to scrape on a lot more stuff as it was slightly lower but no impact or detriment to any other components or sumps anymore!!
