Which car ZR350
OneSpot Gaming did a driving test between the ZR350 and the Jester RR. The above video showcases their overall performance in GTA Online.
It turns out that the Jester RR is a slightly faster vehicle. Its top speed overtakes the ZR350, albeit just barely. The Jester RR also handles better on various types of terrain. Last but not least, it has a shorter braking distance.
Overall, the Jester RR is somewhat better than the ZR350. The only downside is that it's a more expensive vehicle. Some GTA Online players might decide to go with the ZR350 as a cheaper alternative. Nonetheless, both vehicles are just fast enough to win street races.
