)^: this sucks
There's plenty of good 5 lug wheels available... I assume this is why you want 4 lug, I don't see any other reason you could possible want 4 lug.
Which Racingharts did you get?
And you can buy 4lug to 5lug hub adapters (they are like 1" thick... lol, 25mm spacers) so I would assume you could find 5lug to 4 lug...?
