Before I can see new visual effects I would like to see dynamic weather effects, realistic clutch-, brake- and tyrewear, realistic gear ratios and more expensive license to keep LFR'ers out from the community.
Well that's not visible suspension necessarily. Anyway, when do you see the suspension on a vehicle? Not really that much, except on big trucks. I think visible suspension is pretty much the same suggestion as underbody modeling. It is mostly under the body.
