I have made the following changes (so far)
Physics
-Changed engine specifications (Now the 128hp 1.8 and doesn't suffer from the low inertia value)
-Fixed the suspension, new configs
Model
-General model improvements, retextures, coloration, etc.
-New configurations: pop up lights up, rollbar, combination.
-New wheels, 7 spoke LX4 wheels.
-Retextured lights and interior.
-Reorganized gauge cluster.
-New steering wheel.
Car is a WIP. There's still some things with the model I need to tweak.
I like this mod a lot! Even if my taste is biased owning a 1994 Miata. Does handle pretty good, but it acts pretty oddly under two circumstances.
1 is the flywheel weight (?) The car seems to rev up and down really quickly, definitely find a way to slow that down.*
2 is with an open differential. This may be the game rather than the car though but this also may be tied to the flywheel.
Some other suggestions include configurations like a hardtop, R-package aero, and pop-ups, and different wheels, something similar to the daisies or hollow spokes.
