Performance Traction Management
What is this? (in Magnetic Ride Control with Performance Traction Management ($1,795)
Specifically, does the MRC option mean the car will launch better? (assuming it has better traction)

A friend of mine who has MSRC and uses his 'Vette as a daily driver said he wouldn't buy another 'Vette without it. In everyday driving, according to him, it makes the car much more comfortable to drive. Not only that, the MSRC dynamics will change according to the driving mode selection in the C7, getting stiffer in competition modes.
The way it works is that there are metal particles in the shock fluid and a rod or wire running through the center of the shock. The wire or rod has an electric current that passes through it and by varying the current the viscosity of the shock fluid can be dynamically changed in millisecond increments. So, as road conditions change, sensors in the system can stiffen or soften the ride to make the car more stable, whether on the road or on a track. The point here is that it isn't just designed for track duty. It can smooth out a very rough road or dips and keep the tires firmly planted for better control in everyday driving situations.
Any owners on here with MSRC can probably give you a better explanation and tell you about their experience with it.
The one drawback is that shock replacement can be pricey when they wear out.

What it Does
Mode 1 - Wet
For use in damp or wet track conditions by drivers of all skill levels. Engine torque is managed based on wet track conditions. Traction and yaw control are enabled.
Mode 2 - Dry
For use in dry conditions by less experienced drivers, or those learning a new track. Engine torque is slightly managed based on track conditions. Traction and yaw control are fully enabled. This is comparable to the Competition Mode on previous Corvettes.
Mode 3 - Sport
For use in dry conditions by drivers familiar with the track. More engine torque is available than in Mode 2. Traction and yaw control are reduced.
Mode 4 - Sport
For use in dry conditions by drivers familiar with the track. The same level of engine torque is available as in Mode 3. Yaw control is disabled.
Mode 5 - Race
For use in dry conditions by experienced drivers familiar with the track. This mode requires more driver skill than all the other modes. Available engine torque is maximized for cornering speed. Yaw control is disabled.
Off
Stability control of all types is disabled.
Only ABS remains active.

), but...the OP was asking about PTM, which is used to optimize traction exiting a corner.My understanding of PTM is that is pulls timing in order to reduce power, allowing the driver to floor the throttle without causing wheelspin and loss of control (excessive power-on oversteer). PTM uses the wheel speed sensors, yaw sensors, steering angle, and accelerometers in an attempt to determine the optimal amount of power to deliver. It also has various settings that will modify how it calculates the power based on the other inputs. There are settings for (among other things) wet, dry, race, and PTM off.
The more agressive the setting, the more power that will be allowed, but it will still vary based on the inputs mentioned above.
I've pieced together the above explanation from various sources, so some might not be quite right, but I believe it captures the intent of PTM as well as mostly how it works to optimize performance. Basically a traction control system that is trying to improve power delivery.

I read the OP to be asking about MSRC with PTM. Since I don't know much about the PTM part, other than it reduces wheel slippage, I answered the part I know something about, MSRC. Thought I was on-topic, since you get them both in one package. Thanks for the PTM explanation.

Hey guys, basically I want to know whether to get the $1795 option of MSRC with PTM. I don't care about ride comfort or the ability to take turns on a track. If however, the option helps with drag racing or reduces wheelspin when accelerating in a straight, then I'll likely get it.

And to Achmed, I'm more of a road course guy; I don't know enough about drag racing to know for sure if MSRC with PTM would help. I do know that increased weight transfer can help with the launch, and since the MSRC has a softer shock setting than the stock Z51 shocks, it could make a difference in that respect. Still, if you don't need it for the ride or adaptive handling benefits, putting that money towards other mods more suited for drag racing (tires for example) might make more of a difference.
From my perspective the MSRC is a critical option, with or without PTM.

The c6 Zr1 uses MRC to launch and the c7 system is more evolved.
