I have those fitted to my car, they are a simple installation. I can't say how much stiffness they add but I am happy.

Well, given the fact that they're attempting to sell a strut tower bar, when we know (from many sources) that such a product will not allow the bonnet to close properly, I'm not impressed so far.

Jaguar XK8 4.0 (1998) Front Strut Bar / Front Tower Bar

In a photograph they provide at this link, the bar is installed, but the bonnet is removed from the car. You can see the bar laying over the intake manifold, which itself lightly rubs against the bonnet liner when closed. They must have been sorely disappointed when they attempted to re-install the bonnet and close it. But it's not stopping them from attempting to sell the bar anyway (at a low cost of $ 0.00).

Well, there are some advantages to the ultraracing stuff as well.
It does not move
it is quite
lower center of gravity
It does not change the temperature settings in the car
and above all it doesn't need a bathroom stop every other hour.

If you want to stiffen your car why not fit the braces from a convertible.

I spoke with Ultra Racing yesterday & the strut brace will not fit a supercharged car. If you look closely at the car there is a bonnet fitted as you can see the r/s side strut.

Back when I was in the autocross circles with my old car there was a lot of talk about these underbody subframe/frame cross bars. Few guys tried them, but the consensus was no-one noticed a difference (and the times didn't improve, either). If anything you are adding weight. I'd save your money, and if you really want to buy something for your car, buy yourself an exhaust system or just save it for maintenance
