Ignoring the do people drift on 19's discussion as its a bit fruitless as much as people will drift any size (you even mention that yourself), not everyone on dw will be viewing the for sale adds for the sole intention of drifting, they may be looking for the stance look and with those offsets your in that target audience, hence mentioning driftworks and perhaps trying to aid your sale
"Imho", you would be more likely to sell if you split, again, trying to aid your sale.
Do you really want my opinions on Kumho Ecsta's, i doubt it unless it agrees with what yours is, which it wont
