I'm open to both imho, but even for my taste there's a point where it goes too far like the 12"s shown above.
By all means, stretch can be done very nicely indeed, but, I think there are just some silly examples whereby the car imho is dangerous.
I however, find my 255 out front on 9.5"s a little stretched, whilst the 285 out rear on 10.5 is a little too fat for my liking also?
For me stance up to a degree, performance up to a degree, hopefully one w/out sacrificing t'other, but I can sort of understand the appeal of form> function up to a point also
