Is the extra couple inches worth the money? 20x12 vs 20x10?

[Bud311]

Wanted to get a any opinions on if a 20x12 three piece wheel is worth the money vs a 20x10 wheel? You pay a decent premium to get the extra 2". I think the 12" looks really good, has anyone gone thru the same thought process? Any opinions?

The set up I am going for is a 20x12 (335/35R20) and 19x10 in front. It would go on a 1967 Nova (LS7 w/ Tremec 6 Speed)....

I been looking at Forgeline, Fesler, etc. Any other suggestions?

Thanks!!
