Hi Gents, 
  
Couple of questions for a potential new owner, take advantage of your opinions.. 
  
- What is the difference between a 350z GT & the 350z GT4, as far as I can gather it is slightly increased power, some different wheels and a production number badge.. is that it!!?? 
- Lowering springs, your recommendations (Eibach?) 
- If you fit mild lowering springs can the alignment be set up properly afterwards or do I need to consider other adjustable items..? 
- Spacers, your recommendations and what do you go for front and back, just to achieve a neater look of sitting nicely in the arches? 
- What's everyone's favourite stubby aerial? 
- What's everyone's favourite 'must do mod', small things that make a difference to owning your zed? 
- I shall do my homework but also interested on aftermarket exhaust and y-pipe, don't want to break the bank for some true duals and want to look as stock as poss.. 
  
Thanks for your time, look forward to your feedback.
