New Hobby User Group - Automotive Performance

Automotive performance could include: Handling, HP, MPG, brakes, ride, racing, aerodynamics and many other topics

(CR4 Admin Note: March 26, 11:31 EST:

That's a good idea for a group. Per your request, we've added Automotive Performance to the Hobbies User Group. All registered members of CR4 are welcome to join the Automotive Performance group or any other User Group. User groups are a great way for CR4 members to find and network with other engineers working in similar fields or with similar interests.

And to everyone, feel free to suggest other user groups that you'd like to see.)
