This is one of those upgrades that is mandatory for any Hyper 7 user. Since the car does not have a front anti-roll bar by default you will need this one to get full control on those tight curbs. An anti-roll bar at the front of the car will slightly reduce low-speed steering and make the turning radius a bit larger, but with will also make it very consistent. It reduces 'hooking' by preventing front end roll and the car will have more rear traction in turns. Anti-roll bars reduce body roll in turns, so they make the car feel more direct.
