Our Cage Foot Plates Are Laser Cut, CNC Bent And Are Designed To Be Contoured To Fit To The Bodywork Of The Car, Meaning There Are No Large Gaps To Fill With Weld. Furthermore, The Accuracy Of Our CNC Tube Notcher And Mandrel Bender Means That We Can Guarantee Consistency Between The Design And The Final Product: This Ensures Tight Fitment To The Bodywork In Many Places, Meaning We Can Stitch Weld Your Cage To The Bodywork To Increase Stiffness And Chassis Rigidity.

And With Many Things In Life, The Stiffer The Better.
