Who makes the most realistic racing simulator? Since SimCraft makes the only simulators with motion simulation based on physics, we are pretty sure we do. Here is some professional praise for SimCraft APEX Racing Simulators to back up our claim:

SimCraft APEX Racing Simulators provide the best feedback and is the best representation of what we do as race car drivers in real life. If you are looking for the most realistic racing simulator, you have found it!
"I have been in motion simulators before and they were not that accurate...and then I drove the SimCraft motion technology...it is second to none."

NASCAR Cup Driver
"SimCraft is the most realistic simulation solution on the market. Not only is it a great training tool, but it’s incredibly fun, that’s the most important part. All of the controls feel super realistic and very connected to the software solutions. Having the unit has been very valuable to our on-track performance."

Justin Algaier
NASCAR Cup Driver
"There is only one style of sim I can drive, it has to be a SimCraft APEX. SimCraft is the only sim I have driven where the motion feels natural, like driving a race car!"
Spencer Pumpbelly
IMSA & PWC Driver
"I used to strongly dislike sims until I drove an APEX4 GTS from SimCraft, and before I finished my first lap, my opinion of sims completely changed. I had driven a couple before that moved the seat around and since my seat does not move around in my car, I found seat mover type sims unrealistic to drive."
Andy Lally
IMSA & PWC Driver
"With racing governing bodies restricting testing, driver seat time has been impacted the most. Therefore simulators become an important part in a driver's preparation leading up to a season. The brake pedal effort and sensation is really close to real life and the feedback at the wheel and the strength needed to drive it gives me a good workout as well."
