Okay, fair enough about the racing transmission whine. I guess it's a horrible sound that I'd have to deal with. So how about this:
An option to change just the rear-end of the drive train? Or to take a three-speed and add a 4th over-drive gear?
As I've already written in another post they should have separated transmission tuning components into final drive and gearbox:
The gearbox section would have:
- Standard gearbox
- Close gears sports gearbox (with a longish first gear, and all other ones close together; 1 extra gear depending on the car, very slightly increased whine)
- Super close gears sports transmission (with a long first gear and all other ones very close together 1 or 2 extra gears depending on the car, very slightly whine)
- Racing sequential gearbox, fully customizable (fully customizable, 1 or 2 extra gears, full whine, slightly increased efficiency and faster gear changes)
The final drive section would have:
- Standard final drive
- Sports final drive set (a selection of 4 different final drive ratios, 2 shorter and 2 longer than stock)
- Semi-racing final drive set (a wider selection of 8 different final drive ratios)
- Racing final drive, fully customizable (including additional noise and efficiency)
And while they're at it, they could also expand the limited slip differential section, for example true 1-way LSDs, standard fixed setting LSDs, 100% locked differentials, etc. A fully customizable LSD should be expensive and a "last resort choice".
