DMX To Sue Over Arrest?

X -- who was allegedly going 102 mph in a 65 zone -- tells TMZ, "I was going 85 miles per hour ... I know for a fact I didn't go more than 90."

X adds, "I'm used to driving fast, I'm a New Yorker ... but I constantly look at the speedometer when I'm driving ... I need to make sure I don't drive too fast."

The rapper says he knows he was technically speeding, but he feels the cops abused their authority by putting him behind bars ... even though his rap sheet takes longer to read than "War and Peace."
