Have a search on the SVrider forum, look for Zoran's braced arm thread.
He got a stock SV arm braced to use in a tuned race SV (90bhp), but could detect no real difference when compared to stock in terms of flex.
It might look cool but I think this is a bit of overkill for road use. You could spend the same cash on a penske shock and really notice improvements.
If only I had that sort of cash to spare.
