Need help with my Uni Project - Favourite Mods

[ali-c]

I am in my 3rd year at Portsmouth Uni where Im doing Product Design and Innovation.

As part of my Final year project I am researching and designing a product which will enhance the driving characteristics of an everyday car.

So as part of my research I would like to know what modification (small/large/cheap/expensive) you think has given the best driving enhancemnt to your car??

Example: LCA's, Brake stopper, Air Intake.... (mainly 'off the shelf/bolt on' products)

The answers you give will be compliled and included in my project, and will really help me with decideing on what to persue further.....who knows I could end up with a working prototype and eventually and feasible product for you guys!!!!

If you would maybe give a little bit of explanation that would be great but not to worry if not.

Any input on this would be greatly recieved!!!!!

Thanks

Ali.
