19s or 20s

[lordchris]

Alright folks

I have a set of 20 Final Editions at the minute, and as nice as they are i am still hankering for a set of forged lightweight alloys.

Considering 19x8.5 with 255x40, or 20x8.5 255x40

Both the 19s and 20s I am looking at are around 9-10KG so pretty light. My question is, is 8.5 width enough for the amount of torque a 4.2 D3 has?

Note i will be getting it mapped shortly.

Would i be better finding a 19x9, would the extra width of the 9 give better grip. Which do you think would have better handling 19x8.5 or 20x8.5. For the wheels i am looking at the 20 might actually be marginally lighter..

Price wise the 20 will be the dearest option.
