3 3/4" Spot Mirror with bracket for 1-1/2 and 1 3/4" roll bars Mounts on driver's side or passenger's side Adjusts easily Bolts in place solidly Todays race cars are harder to see out of than ever. Head and neck restraints limit head movement and the new seats make for big blind spots. Longacre has created a new spot mirror designed to get back the lost field of vision. The new mirror locks into place insuring vibration will not affect the adjustment. The clamp on design makes for a simple installation on the driver or passenger side and the mirror picks up a wide area. Drivers can use the mirrors to make sure they are really "clear" before chopping into a corner making for less on track contact and another improvement in driver safety.
