Apex Assassin Autosport's Praga R1 "Assassin Package" is a top tier upgrade package for your R1. While the Praga R1 is already an amazing product out of the box, you may find yourself lacking horsepower in some racing organizations such as NASA, where we compete in the Super Unlimited class. Or maybe you just want to get pushed back in your seat when you stomp the go pedal.
The Assassin Package is capable of an easy and efficient 150+ horsepower gain over stock with headroom for more. This package features top of the line products as well as custom in-house built parts that are unobtainable anywhere else. With our upgrades you can expect 160+ mph top speed at tracks like Sebring International Raceway, putting you above GT3 and LMP3! Now offered in two stages to suit your horsepower desires! |
