While GT3 has more length than the RS, the latter has more height and width. The GT3 takes about 3.9 seconds to hit the 60 MPH mark. The same feat is achieved by the GT3 RS in about 3.2 seconds. Other than differences in the specifications, there are also a few distinctions to the interior as well as the exterior. For instance, the GT3 RS comes with a lofty spoiler that is absent in the 911 GT3.

We Recommend

There are only a few additions as you go up to GT3 RS from the base model, the GT3. The most important of which is the enhanced power and torque. However, the max speed goes down in order to compensate for the inclusion of large tires. The design and aerodynamics of the GT3 RS are more aggressive than its sibling.

Besides that, there aren’t many differences between the two makes. The price gap between the two is about $44k. Things are different for racing coupes as that of other non-racing rides. Therefore, GT3 is for casual racers those like to put a load on the accelerator not often, whereas GT3 RS is for those obsessed with speed and performance.
