Anyway, I was pondering on some additional upgrade parts to fill some of the unused mount points and fulfil some roles that i don't know of having any sort of IC means of accomplishing the the moment. Please feel free to add your own suggestions here!
Car parts
Front Mount Point
Badlander Action Parts Faraday Shield
A faraday shielding that is installed on the front mount point, the shielding provides protection against the effects of an EMP against a vehicle. While the initial blast will still kill the engine, it can be quickly restarted. The shielding does not however protect the vehicle's security system, so owners are advised to move out of the affected area quickly, lest their doors be unlocked for them.
Rear Mount Point
Street Ninja Stealth Muffler
The Street Ninja Stealth Muffler is so effective at masking the exhaust note of a vehicle, that not only is it impossible to tell a vehicle is running at a glance, but it's possible to completely miss one even driving through the same block as you.
Roof Mount Point
Badlander Action Parts Light Bar
A high intensity light bar mounted to the roof of a vehicle. The collection of spotlights aim in every direction, not only lighting up your immediate vicinity, but all adjacent areas as well!
Bike Parts
Motorcycle Fenders
SHI UrbanLight Fenders
Much like the SHI UrbanLight side panels, these fenders provide street glow illumination. Available for both the front and rear fender!
Motorcycle Fairings
Badlander Action Parts Drop-Tanks
While they don't actually drop off, these motorcycle fairings do perform the same function. Each fairing increases the fuel capacity of the motorcycle it is installed on, without adversely affecting the stylings or aerodynamics of the bike.
Motorcycle Transmission
SHI Tall-Geared Universal Motorcycle Transmission
Motorcycle Transmissions are normally geared short to maximize acceleration, but the SHI Tall-Gear line is designed to keep your RPMs lower longer. Equipped motorcycles don't accelerate as quickly from a stop or going around turns, but fuel economy is dramatically improved!
