Trying to decide which lens to get for low light shots. Most of the shots I'll be taking at night will be drag racing photos so I need something quick to focus. On the fence with several choices of 50mm Nikon lenses but can't decide.

I've used the 50 1.4D for a number of years on a D100, D7000 and D600, mostly in lowlight situations, but never for drag racing. Most are indoor shots. Haven't noticed it to be slow focusing. All of my racing shots (sports cars) have been in daylight with 2.8 zooms.
I don't think you can go wrong with any 50. I bought this one a long time back when I didn't know any better.

I concur. You really can't go wrong with any 50mm lens. They are all fantastic performers. I think you would be more than happy with the newest 50mm lens, the 50mm 1.8G. It is relatively cheap, focuses a little faster than the 50mm 1.4G and is extremely sharp. And I'm sure the high ISO of the D7000 will be more than enough to compensate for the 2/3 stop you loose from not having a 1.4 lens.
I've never used a D7000, but I'm sure the focusing motor in it is fast enough to not discredit the D lenses either.
I'm not sure of your FOV, but, I wouldn't rule out the 35mm 1.8G. Its the little cheap gem of the DX world. And I find that in extreme low light situations with very slow shutter speeds, it out performs the 50mm 1.8G by a nudge or two.

A 50, on a D7000 has a narrower field of view than on a FX or film camera so if you are relatively close the focal length might be right for you. If you are in the stands, 50 is going to be too wide.
For very fast action that is predictable in position versus time, pre-focusing on a point, manually, would allow the camera to be very responsive, without waiting for AF locking. The 50, all of them, are relatively "casual" in focusing speed. I have a 50 1.4, 50 1.8D, 50 1.2 MF and a Sigma 50 1.4, and all pf the last 3 are faster in focusing than a 50 1.4. For value, it is really hard to beat the 50 1.8g and it is likely better optically than the 1.4 version. The Sigma is fast but the corners are not as good as the Nikon 50 1.4 or 1.8G. It is a superior portrait lenses however with beautiful bokeh.
Before deciding on a focal length I would go out there and shoot with a zoom and see what focal length works best.
If you are shooting RAW, don't be afraid of getting under exposure with a D7000. By using a reasonable shutter speed, and stopping down just enough to give some flexible DOF, so your shot is not blurry from motion or lack of DOF, ignore the fact of a low ISO setting gives a very dark or black frame. The data is there and color and detail will probably be better when boosted in post processing than running high ISO. So think of optimum FL first, and 2.8 or faster lens will be plenty fast enough to use a reasonably fast shutter speed without having to use excessive ISO, provided you intend to do post processing.
If you do not want to MF, and depend on speed of both the AF system and lens to capture such a fast receding object, I would look into a 70-200 2.8, either VR 1 or VR II. Although it is moving a lot of glass, it is one of the fastest focusing lenses I have. If I just had to have the extra light and can accept only part of the car being in focus, I would use the 85 1.4.
If you are shooting from on-track, a wider angle lenses will present a an easier focusing task. The deeper DOF would be much less critical. A 35 1.4 Sigma is the best "Normal" lens on DX and a good price. I would use my 24 1.4 if I had close access. The 28 1.8G is awfully good also and much cheaper.
