Beta Backyard Kart 0.17.6

This update definitely expanded in scope beyond what I had intended. There was so much I discovered while working on the configurations that I figured I'd push this update back a bit.

The changes in this update make the 250cc and Predator configs feel like I am driving the rental karts at my local track. Especially in vr. The axle hop is very predictable now and the tire bounciness is only really present at speeds below 15mph or on very bumpy roads like those made of meshes.

Due to this, and with the changes to the Standard frame configs altogether, I am feeling like I am finally getting close to something I could consider a 1.0 release. I still need to work on the independent rear frame since it likes to explode and completely redo the rear coilovers since they do not act as I would expect.

Below is the list of changes for this update:

Frame:

• Independent rear
  • Reweighted the frame to be more realistic
    • This one was actually much closer than the standard frame with only about 30 lbs of weight savings
  • Applied the same rigidity changes as seen on the standard frame
• Standard
  • Further tweaked beam spring and damp values

Suspension:

• Independent Rear
  • Changed torque reactions to align with the standard frame's axles
  • Changed some beam values
• Front (Standard and Welded)
  • Added meshes for the front brakes

Wheels:

• Slightly modified the kart wheels
• Added even smaller dark owl wheels

Tires:

• Significantly modified the kart tires
  • This does not change the handling a whole lot, but it does improve stability at higher speeds

Engines:

• Predator 212cc
  • Changed sounds to be less harsh
• 500cc
  • Changed engine sound to the i4_4 sound
• 600cc
  • Changed engine sound to the i4_4 sound
• 900cc
  • Changed engine sound to the i4_4 sound
• various tweaks to engine sounds across the board aside from the 250 and 350cc engines
• Increased friction values and reduced engine braking torque

Transmissions:

• Reduced the gear whine for the 6-speed race transmission
• Made the race cvt and centrifugal clutch transmissions more stable

Transfer cases:

• Introduced One Way Viscous Coupling to all of the transfer cases
  • This significantly reduces the strange oscillations in the powertrain that result from the relatively low gearing.

Misc:

• Added the dark owl bodykit
  • This one adds significantly more downforce to the front and even further lowers the center of gravity compared to the sbr bodykit
• Added the race kart bodykit
  • It's lighter than the others at 30 lbs vs 50
  • It protects the tires
  • Has a slight downforce effect on the front end.
• Retuned almost all of the welded front configs excluding the V8, Vivace, and Autobello configs
