17" RIMS 315/35-245/45 ON A V6 CONVERTIBLE ????????

Howdie,
I have recently posted a thread about putting some KUMHO ECSTA 711 tires on a V6 CONVERTIBLE 225/50/16 Front -245/50/16 Rear--lowered w/EIBACH kit 1.1" Just did that a couple of days ago BUT am not really satisfied w/the looks......

So I was thinking about getting new 17" 10.5" Rear and 9.0" Front `03 COBRA SVT CHROME(Replica) Rims w SUMITOMO 315/35/17 ZR-245/45/17 ZR tires(about $1100mounted and balanced).....would that be too much for a V6-weight wise, Any suggestions on the tire sizes that I should use ?????
Thanx

What????? Nobody likes the Idea of 315s in the Rear ???? I havent seen any yet......that would change I supose ))))

Thanx AP1995V6
I was thinking about that, maybe a 275/40/17x9"
