With a 503 - horsepower version of the 4.7 - liter V8 from Aston's GT4 race car and a fully adjustable suspension, this trackday Vantage rides on 19 -
inch centerlock wheels and Michelin Pilot Cup 2 tires.
The GT had already featured a radically styled body, but the GTR took this a little further with features such as a very large rear spoiler bolted directly to the chassis like a true race car, 18
inch hollow magnesium Speedline
centerlock wheels, pneumatic air jacks for raising the car in the pit lane (like the SV - R, it was too low for a rolling jack), and an emergency fuel shutoff switch on the left front fender.
