Front stiffeners are a common thing on many a TC.. These help with stopping the bonnet flexing on lightweight bodyshells, but like all parts they can also help with tuning.
I made these when the TRF421 was released and have passed the files to many friends and you can see these on a range of drivers cars now. However, I have nevery actually put them on the site.. well now here they are..
The one that most drivers run is the Soft version. This allows a little more flex at the front of the bulkhead. It makes the front end more stable into the corner.
There is also a stiff version if you want to keep more initial bite into the corner.

BTW I've eventually set up a decent repository for all of the free 3D files that I have designed over the years.. I'm slowly uploading them when I have time.
