1st thing to do is just wait a couple days to see what you've got once it arrives,
My personal opinion is that a "stg 3" car is a good driving road car
I.e greens, 3bar 500 cooler 3 inch exhaust and either t3 for punchy responce or t34 for bit more power,
Obviously proper chip to suit,
post up some pics when you get it to help identify what you have
Differant people will have their preferance but thats tried and tested and reliable
