lanted brackets are stronger than the rest! They are made from 3/16th inch steel making the welds stronger and more durable. The Planted bracket will not bend or warp with heat whereas other brackets can be bent by hand.
Planted brackets are more versatile with predrilled slots for sliders from most major aftermarket seat manufacturers like Sparco, Recaro, OMP, Cobra, Racetech, Status, Corbeau, Bride, Momo, etc. There is also extra material for direct mounting when the driver wishes to eliminate sliders altogether.
