Hello,
Does anyone know of the torque spec for the undercarriage cross or sway brace? I pulled the ones on the car to remove rust and refinish. Thanks

 

There are several braces (in rear and front). Wherever they mount to the subframe/uni-body the torque spec is 70 Nm and where they mount to the body, it is 48 Nm.

I recently took my front brace off when replacing my downpipes.
Such a detractor from the overall engineering of the car.
Everywhere you look under the car, it appears brilliantly executed using modern well finished light weight materials - except for the bracing front and back.
I have never seen such a poorly made chassis parts on a modern car.
Its as though someone accidentally fitted parts from a Russian tractor (from the 1940s) - they do not belong on this car.
I have owned my car since almost new and it never sees salted roads (and rarely rain) and is always garaged.
Despite this, the front and rear bracing are rusting through.
When I took a wire wheel to that crude pig iron brace, it revealed rust under the paint and a very crude pitted surface.
I took off as much as possible, but I could not get it all off due to the pitted steel bits welded together, hiding some surfaces.
Disappointing and off putting.

 

Do we know of any aftermarket braces with higher quality ILO De-rusting and re-finishing?

 

I would replace the brace if there was a lightweight quality replacement available.
I understand that this bracing is Tata's contribution to the F Type - obviously part of the economics of producing this car.
However, I equally appreciate that in the process of producing this car, there are always compromises in design, engineering and economics.
I can almost imagine the meeting in which the car's designers conceded to using the cheap bracing while maintaining design and engineering in other critical areas.
Car designers and engineers don't get to realise every element of their vision , so in the end, I do applaud Jaguar for taking this beautiful car to market and overcoming the challenges of doing so in this very crowded and competitive market.
It's just disappointing that this bracing is so utterly crude, pitted steel coarsely welded together, and clearly made using primitive casting methods.
Illustrates to me a glimpse into the challenges of operating a premium business with heritage and modern day design talent, under the ownership of a company that has the capital but does not share the same values.
