The peculiarity is that the model has the same external properties, but with a smaller number of polygons, which does not strain the game so much. LQ is also a demo version of what to expect when ready.
There are 3 body kits: BN Sports - Alien Rocket Bunny - X-Flow, wheel - Cutter Pandem (only an extension, you can put it instead of the rocket bunny extension and use its bumper) - X-flow.
