xREL.v3

Update v1.2.4428:
Better car handling, due to re-balanced tire model, suspensions, brakes and many more.
improved tire models, pressure calculation
improved performance for lower end systems (especially in racing and mechanic mode)
Home with sleeping (motel)
Two new sport cars from 80's, new engines and parts
Added euroa differentials in range of 1.2-2 ratios
Color coded Differentials shows which diff is better for a job. RED = stiff differential, YELLOW = mediuma, BLACK = soft. Use stiffer differentials on high torque engines to prevent too easy wheel spin in corners. You want more drift? Use a softer one!
Improved updaters, with backup of your game saves (in case an update would brake it, you can revert)
No more restart for a street race of challenge allowed
Added sound for spinning tires on dirt
Updated lap times to fit to our new physics
Fixed aerodynamics calculations
Fixed store issues, when you might end up with loosing your stuff
Fixed lights on Imalona
Updated localization (Spanish is coming!)
Update several 3D car parts and models
Bugfixes

NOTE!
Due to the changes in physics models and parts, you might need to re-balance your own setup. As a basic guide, you can follow these:
Lower tires pressure if cars slides too much, usually pressure should be between the middle and lower end of green zone
Too much oversteer => lower rear tires and/or rise front
Too much understeer => lower front tires and/or rise rear
Can't get any grip, use wider tires! Heavy and fast cars should have 265+
Use stiff (RED or YELLOW) differentials if wheels spins too easy in corners
Use the right type of tires!! Dont race with slick on dirt...
Change sway-bars (antiroll bars) to adjust "bouncing" effect at punch start in corners
Change you suspensions if your car bouncing too much on a track
Your car is strange in corners and straight as soon you accelerate or turn? Check your tires, sounds as a flat tires!
