Was interested on what peoples opinions are when it come to building a high powered s2, im thinking of 300+ bhp.

Apart from the engine / gearbox, what would be on your list of things to do, such as :

1) Any body strengthening?
2) Are driveshafts up to the job?
3) Rose jointed TCA's?
4) Suspension / Coilovers
5) etc...

What would you do in order to do it properly ?
