yeah i believe the brakes are bigger.. but only after/or up to a certain year.. cant remember what way round that is..
they also have ABS too.. not sure if any 8v's did
My '96 8v has ABS. According to the specification/history section of Parkers Car Price Guide, all GTi's had ABS as standard from October '94 onward, together with drivers airbag & immobilizer.

Although, the trader I bought my GTi from said it didn't have an immobilizer
