Since I fitted my lower brace to the car I get a knock/creek from hard cornering. I cant see any signs of movment under the car. But am not over sure if I have done the wishbone bolts up tight enough. Anybody have any advice or exerience with a similar noise or having fitted a brace?

I used to get the same occasionally when i had the lower brace on my P1. I eventually took it off as I mainly put it on for track days using slicks and haven't been on a trackday for a few years only to find all the bolts bent to buggery (technical term alert) - possibly from the cornering forces with the slicks?

 

I have run a Whiteline front lower brace for 3 year, 120 hillclimbs and 8000 road miles without any issues at all.
Put it back on yesterday after changing down pipe.
I do the wishbone bolts up to 50 Lbft torque as there is a crush tube in them although i have Polybushes everywhere.

You shouldn't have an issue at all.
