Big vote for RBF600, I've run it in all my cars.
DS2500s/A.N.Other performance pad and better fluid make a massive difference. Braided hoses will stiffen up feel too.
Possible downsides are faster wear on the wheel bearings, due to the heat and you might melt the odd CV gaitor on a really hard track day... but for a daily hack, no issues.
