Actually, procarparts.com has a strut tower bar that clears the oil cap... I just bought a set of the front and the rear, they were $20 a piece, They're a hell of a lot thicker than the megan racing bars, and dont flex at all. Just a word of warning, though, they're not pretty. Mine had polishing compound stuck in the corners and the holes drilled in the bar (that probibly dont do too much) aren't drilled very well. here's the pic of it installed in an actual 2gnt engine bay,


and here's the link... They have other bars on the page, but these actually had pictures with them, so i went with those...
