SCCA mandated for P1, P2, and FB classes
The magnets on the back of the AiM Solo lap timer makes it easy to move from car to car, but once you're in the second car, you need an extra mounting plate for the magnets to stick to. This is the same steel mounting plate as included with the Solo and SoloDL. It has countersunk holes for mounting screws and tabs to keep the Solo from sliding off under high shock loads.
Includes 2 countersunk 4x0.7mm socket-head screws (to fit the countersunk holes in the plate) and 2 3x0.5mm socket-head cap screws with washers (to fit the threaded inserts in the back of the Solo). This is the "DNKTKPFSOL5 data box mount" required by SCCA rules for P1, P2, and FB classes effective 02/28/2014
