It really depends on what aluminium alloy Audi used for the ASF that might determine any heat treatment is require in the welding of the reinforcement plate.

Watching the R8 factory documentary, the ASF frame is put together on a jig and welded in place by their welders like a non heated aluminium alloy.

The heat-treatable alloys are very susceptible to time at temperature; the higher the temperature and the longer at temperature, the more significant the loss of strength in the base material adjacent to the weld.

The non heat treated aluminium is not so susceptible to loss of strength to time at temperature.

This is why it's important to use an aluminium specialist when doing this retrofit. Aluminium has a different melting point than steel so it doesn't glow red like a steel weld. If the welder is not an aluminium specialist, they can overheat and damage the ASF frame.

While the retrofit weld does appear to be more extensive than the factory weld, the whole uncertainty surrounding this is whether there was any special heat treatment done/required in the process. I think the uncertainty is whether doing the post-factory weld actually weakens the aluminum around the area - not just the weld itself...

If it was a no-brainer, I would probably do the retrofit as well. But now I'm uncertain.

Is it possible to do PMI and check the type of material? Are some of you working on oil and gas or have access to a PMI machine?

Here's a plate closeup - shows material type - not PMI but ...

Here's more info on the aluminium used in cars.

I think Audi is likely using the same material (heat-treatable AlMgSi 6000 series alloys) for the reinforcement plates as the frame.

Structural reinforcement done by Ricky. Bits of other work including replacing mags with passive dampers. The car actually feels so smoother.

I guess the mag shocks would have been near the end of their life. Ricky as usual has been absolutely amazing.

Ricky is the best! Good you got this retrofit done by him.

You guys in the UK are very lucky to have him nearby. :)

To be honest I would not trust anyone else to do it and would have not got it done but for him.
I agree. Seems there's a lot more to it that just "welding the plates". I believe Ricky uses Audi-approved welders which should provide a lot of comfort to future owners should you decide to move her on.

Do you have his contact details? Sent him an email that someone gave me but got no reply.

How long did it take, did you leave the car with him also do you know if he removed the dash etc

Personally, I don't think I'd put on the reinforcements unless you have an issue. Welding changes the temper of the metal in the heat affected zone around the weld, weakening it. There's no way to re-temper it (without full disassembly and baking it)

I have doubts the heat from welding the plates would weaken the surrounding aluminium to less strength than the flimsy weld on the shock tower from the factory.

It's a risk either way. More reason to make sure you guys have an aluminium specialist to do this retrofit so he/she doesn't overheat the surrounding area.

There's no heat treatment done to the aluminum chassis parts during construction welding, and they're mainly done by hand!

I know I'm beating a dead horse...... Did we ever confirm the manufacturing years that lack the structural reinforcement?
I am looking at a 2011 R8, however the build was likely in the latter time of 2010. Can the VIN confirm any data? (IF so, who would have access to this information via the VIN?)

I know the PPI will confirm, just doing my due diligence......

Thanks
Ryan

It was around 2010/11 but no VIN look up available. Only way to check is to take off the boot inner and look yourself.
