What kind of tires are you running? 285 is pretty wide! Try lowering the tire pressure to 30PSI, or even 28PSI. Also, an aggressive rear alignment will decrease traction in the back, I'm at -2.5* and I will soon change to stock or even -1* camber in the back
changing to a lightweight flywheel will 100% change boost characteristics which wont have been tuned for, i.e faster building of boost @ a certain rev range... drop ess an email and let them come back to you ;-)

iron forget all these massively wide tyres, drop in a proper road legal slick, like the ps cups and a 265 section will have MORE than enough for anything your car can throw at it.... downsize to an lightweight 18-19" and revel in much better traction and response, in reality the 19" lightweight options are that good now and as light as the 18s, you can still retain good looks and have a great, responsive vehicle...
