ABS on the VX is indeed gash on track, so most of the trackday VX'ers have a cut off switch.
However if you drive like a girl on track (hello !

) then uprated pads make a massive massive difference. In saying that the lardy VXT weights 100kgs more than mine.
I recent post on SELOC summed it up for me when the guy said in isolation a VXT is stunning, but compare it to a S1 / S2 / Exige and it can be found wanting in certain areas. But compared to everything else on the road it is just that - stunning. Tis a hell of bargin tho.
EDIT : in the cold light of day that was far too harsh! The brakes are exactly the same as a Lizzy, only they have servo assistance and ABS. As i've said the ABS can be a bit problematic when it gets hot on track, but other than that its ok in general road use. I've stuck Mintex 1144s on my car and they are night and day compared to standard.
Focus ST estate, i3s and more pushbikes than strictly necessary.
....did i ever tell you about the Evora and VX220 i used to own?
