Front suspension. The basic suspension layout of the escort Cosworth is as follows: Front suspension consists of McPherson struts with lower control arms which are fixed to a bridge going under the engine to the other side of the car. Then a 28mm anti-roll bar is attached to the lower control arms. The anti-roll bar then passes through two bushes that are fixed to the chassis with four bolts and a bracket each. The anti-roll bar not only controls body roll it also has the purpose of controlling the for-aft movement of the track control arms. The shock absorbers are hydraulic, double-acting. A very uncomplicated and simple setup, but it works non the less. |

Rear suspension. The rear suspension is a more complicated matter. It kind of consist of three parts: The tubular subframe or crossmember as it's also called, and the two y-shaped trailing arms. The crossmember is a long steel tube that's bent on the middle and passes over the rear diff housing. It has three attachment points: The rear diff, which in its turn are held up by the crossmember and a rubber mount directly to the chassis. The crossmember and rear diff is bolted together using 4 bolts that goes through two metal plates welded to the tubesection of the crossmember. Making them for practical purposes one thing (as far as stiffness goes). The crossmember is also attached to the chassis at each side. This is done by a big bolt going through a big rubber bush that's inserted into the crossmember. The bolt is then fastened in the chassis. To stabilize this there is a metal plate at the bottom of the bush that the bolt goes through. This plate is fixed to the chassis with two bolts about 15cm in front of the bush. The trailing arms are each fixed to the crossmember with two metal-to-metal bushes. One that sits at the outer end of the tubular section of the crossmember, the other sits at the plate that's attached to the rear beam and diff housing. Then there is an 22 mm anti-roll bar that's attached to the trailing arms about midway on the arm with a linkage. The anti-roll passes to the rear of the diff housing and goes through two small bushes that's attached to the chassis with brackets. The hydraulic, double-acting shock absorbers are attached to the very rear of the trailing arms. The springs sits in a recess in the trailing arm without any fastening, with bump-stops in the middle. The springs won't move because of the compression it receives when the trailing arms are mounted to the crossmember. |
