Research Facility question

If I sell my Research Facility when I get KERS, would Reverse Engineering, DRS, and KERS still be available for use?

One person said yes, and another said no that responded.  I just want to ask just in case I need to sign a driver with a large fee.

Once you have all that researched, you can sell this facility, you won't lose anything. I've sold it a long time ago and I have no problem activating KERS or DRS or copying parts :D

Okay thanks.  Much appreciated.

I have buyed the DRS research facility, but I dont'n know if it is working already. I buyed two races ago. ¿¿How does DRS facility works, how do can I know if it is working??
Thanks in advance for your answer.

The DRS system should work automatically during races Fransisco, as long as it's Lap 3 & beyond, and if your within 1 second of the car in front of you, even lapped cars.  You don't have to press the button to use it in the free and 2D viewer.

Thank you Jeremy.
