Sorry about fb id, we can discuss anything here, you will get more info here because there are so many people to help you out. About the looks you can add rims and wider tire it will also improve stability go for 165/70/13 with alloy rims. Unfortunetly there is no good body kit available for WR, original one looks awesome but has high price tag.
Install good rear door speakers and you will have good sound for normal use, it will cost you 3k to 4k original one sony, kenwood or pioneer.
