For mango vinaigrette, combine mango, cilantro, green onion, ginger, 1/4 cup lime juice and rice vinegar in medium bowl. Cover and chill.
For marinade, combine remaining 1/4 cup lime juice, garlic, salt and pepper in small bowl. Using kitchen shears, split each lobster tail in half lengthwise. Pour half of marinade over lobster tails.
Grill lobster tails, meat side down, on grill rack coated with nonstick cooking spray over medium heat 2 to 3 minutes. Turn tails over and grill 5 to 8 minutes more, basting with remaining marinade. Remove from grill and serve with mango vinaigrette.
