Top 5 mods for street use

I have a few questions I thought might be fun and informative for us new to the site. I've searched forums, but didn't find specific topics so if this has been discussed, please send a link. If not;
- Top 5 (or how ever many you want to add to any list) mods for acceleration
- Top 5 overall performance mods (Handling, wheels, weight reduction carbon fiber etc)
These are for the average budget, not for expensive mods like bigger turbos for example.
As well is there a trusted app anyone uses for timing a 0-60 run?

If your state allows, add on Black Boosted catless downpipes and get the ECU tuned with the new setup.

The original owner also put it on a E50 blend of gas, and results from the dyno test can be seen here:
