Say goodbye to cowl shake and hello to improved handling. Our chassis stiffener provides a rigid framework under your 1966-1994 Alfa Romeo Spider to eliminate chassis flex, ensuring correct suspension geometry during hard cornering. Your car will feel more stable and solid, turn in more accurately and corner more quickly. The longitudinal rails, of steel heavy-duty box section, mount to the chassis via the steering gearbox and idler arm holes in the front, and tie to the front of the lower trailing arms at the rear. The side pieces are also of box section, and are removable for servicing components.
Because some Spiders have settled over the years (or were never "square" to begin with), your mounting holes may be off a bit. On our first test car, we used a block of wood and a jack to raise the middle of the body on each side, just enough to shorten the distance between the front and rear of the car by about 1/8" or so. By installing the stiffener without enlarging or moving the holes, we essentially reconfigured our car to the standardized dimensions of the stiffener. Most customers have been able to install the stiffener without doing this (we've sold quite a few).
If your car has exhaust headers, call us before you order your stiffener; you may need the optional front cross piece designed for headers. As a side note, from an engineering standpoint, the majority of the added stiffness is created by the longitudinal pieces--not the cross braces.
Finish is black powdercoat. High-grade fasteners and instructions are included.A final note: in our photograph, the portion of the stiffener that is closest to the model's toe is actually the top front of the passenger side (this bolts through the 3 idler arm bolts). At the top of our photo is the rear of the stiffener, where it bolts to the trailing arm mounts.
