Wait a minute - the Focus RS has better handling than the MINI. I find that hard to believe.
It must have better shocks on that the stock MCS, but i think most of it is down to your driving style. I think somebody needs to go on a course
I've never been outwitted with regards to handling.
Incidentally, once the strut brace has been sized to fit your chasis, then you can take it off and refit it with a normal spanner. Although using a torque wrench is ideal, and if you buy one for your wheel nuts (£70) you can use it for loads.
