OK, so you like to play! track days are just the biz to find out what your car, and you can do! I would also consider fitting a brake bias valve as well..£60ish from Demon Tweeks, and watch your lap times drop! well worth the extra expense, and dead easy to fit, allows you to dial in the amount of pressure to the rear brakes, to almost nothing, so that your driving on your fronts only.. well almost!
