i am fitting a sparco front strut brace to my car, what torque setting shall i re- tighten the nuts too,

 

IIRC the loading experianced by a front strut brace is a shear/sheer(?) force, which is a side ways force exerted on the fixing bolts/screws and so there is not in fact much torque needed to secure the strut brace in place,Just use some thread lock to stop the bolts vibrating loose once tightened up.
