How to launch a manual car at the track?

So when i move up to the line at the track to race and stop, My Clutch is in, 1st gear is in, while tapping the gas to the right rev. Guessing it to about 2,200 / 3,000 rpm. But while in 1st/clutch in/and reving i see my car slowly starting to move forward. Does anyone know how do i launch it without it slowly creeping before going?

Why are Mustangs so overrated?

Don't get me wrong I like them but they're just so overrated. And I'm saying this as a guy who likes Ford. They're not the fastest, not the best looking( in my opinion), don't make the most horsepower or torque, so why?

Mustang left and right lower control arm rotten?

I have a 1994 Ford Mustang; have owned it since it was new. I was recently told that my left and right lower control arm mounts are rotten. I have tried doing research on this and can't find a straight answer. What will happen if and when they rot through? I would take a picture but I do not know where to take a picture. I can only seem to find information regarding the lower control arms themselves, not the mount. Luckily this is not my main car and does not get many miles put on it.

My next question would be has anyone else heard of this happening, and what is the approximate cost to get it fixed (I know it depends on the car and many, many other factors).

Just one other thing, the car is not doing anything out of the ordinary as of right now, the steering is fine and it drives very smoothly. I was told that mechanically the car is in good shape (transmission, engine etc.).
