Has anyone done 300KMH?
The 996tt and the two RS4 in front of me hit 300Kph, but I got scared after hitting 260Kph, the car was still accelerating. Could this car hit 300kph?

The thing is limited to 255-260 Km/h, so unless you remove the limitation (easy thing to do) it will stop pulling at that speed, mine stop pulling exactly at 263 Km/h.
Without limitator top speed is about 290 Km/h

the car will stop accelerating b/c of drag b4 it runs out of revs
i believe that these cars r geared for 180mph+ (i think its 182 or 188)

all those high speed driving are damaging my front grill, front bumper, hood, fenders, radiator, windshield, head lens, fog lens, side mirror... I've already tried my best to keep 20 car length from those cars specially the R-compound tires.

It was extremely dangerous even I only hit ~210km/h at the No.3 Expressway. The C55 acceleration started to slow down after 176km/h and when I managed to reach 210km/h traffic in front was getting dense.
I must admit the engine brake of C55 is superb. :p
If Raywong tells me the best time , best place to test top speed, I will try 250km/h. And true, the highways have too much rubbish which had caused my frontend over 50 bits of body paint drops already.
