TAILIEUCHUNG - Installing a 4-Link Rear suspension & 10-Point Roll Cage

Whether mode choice yields expected impacts on daily activity level remains an open question. Available research confirms declining activity levels for children (Dietz and Gortmaker, 2001; Trost et al, 2002) and adolescents (Sallis, et al, 2000). However, studies evaluating the role of walking to school have been mixed in finding statistically significant increases in children's daily activity level (Krizek et al, 2004). For example, one study found no effect on total activity for five-year-olds driven to school (Metcalf et al, 2004); another found increased total activity correlated with walking to school, yet with statistical significance only in boys (Cooper et al, 2003). . | How To Pro Street a Unibody Car Installing a 4-Link Rear suspension 10-Point Roll Cage Cars with 4-link rear suspensions and full roll cages have long been common on drag strips. After all the cages offer the greatest amount of protection for the occupants during mishaps and the 4-link offers the greatest amount of adjustability for maximum traction under a wide variety of track conditions. As can be seen in these before and after photos of a 1963 Nova the installation of a 4-link rear subframe allows massive amounts of rubber to fit under a car. In the foreground are the components that are included in our basic rearsubframe kit. The first step in a project to upgrade the rear suspension of any car is to make sure that the axle centerline will end up back where it started. Here a measurement is taken and recorded of the stock location using the door opening as the point of reference. Reference points are also critical under the car for fabricating the new subframe in this instance the front of the transmission crossmember-mount is the fixed point choice used for measuring back to the front of the axle housing. The location of the front subframe crossmember is specified in relation to the axle centerline in this kit 25 inches forward. Keeping in mind that there is a 1-1 2-inch difference between the axle centerline and the front of the 3-inch-diameter axle tube 23-1 2 inches is subtracted from the 73-inch reference distance this distance is then measured back from the transmission crossmember and marked on the car s floor which will be cut along this line.

If a torch is used to cut the sheetmetal be sure to have a water sprayer visible under the wheel well on hand to extinguish the flames that will probably result
