Any tips on what kind of lug nuts to get for these? (both spec-wise and color-wise)

Are there enough turns available on the stock studs? I don't know whether the depth of the hub part of wheels is a standard thing or varies model to model.

Also, is there enough space around the lugs for a thick deep socket, or does one need to use a thin/special socket?

These are the lug nuts I got, but any M12x1.25 conical lug nuts will work.

They work just fine on the stock studs and I use a standard 17mm deep socket for them.

OP good looking on the 86. Maybe my big spring purchase

They do make the TC105X in a 18x9.5 5x100. I think it's new. Offset is +45 though.

Yeah, But I went with the te37 saga already :)

Would that fit even with coilovers? Seems like it would rub somewhere.

My enkei raijins are 18x9.5 with the same offset, no rubbing anywhere

How much front camber are you running?
