wells with backing plates as insurance. If your car rolled onto its roof, would the force applied in compression to that thin floor/wheel well withstand this force without ripping through?
The next thing to be compressed is your spine!
REDLINE Harness Mount and Roll Bars fasten to existing reinforced factory seat belt mounts. These areas provide far greater strength than flat sheetmetal floors or wheel housings. In the case of the Harness Bar (944), any forward longitudinal force is transmitted into the boxed section C-pillar, which is far stronger than the B-pillar. With the Roll Bar, the loads would be transmitted through the reinforced factory seatbelt mounts in a parallel (tensile, or tearing) fashion -vs- the perpendicular (or piercing) force applied by most bars into thin sheet metal. Is it easier to tear a piece of sheetmetal... or poke a hole in it. See what I mean?
Perhaps the best feature of REDLINE Bars is that installation is easy using regular hand tools, require NO PERMANENT MODIFICATIONS to your car's interior, and for those still driving to events... they take up very little room! They are constructed of MIG-welded 1½" and 1¾"x 0.120 & 0.95" wall mild steel roll cage stock.
