Building a racecar is not the most affordable endeavor on earth when you factor in quality parts and labor to have things like chassis work and fabrication done by a reputable shop. Having the ability and tools to do the work yourself can save a lot of money, however, you still need good parts to create your car. One of the things a DIY type can do at home is building a four-link suspension and David Zimmerman from Team Z Motorsports has provided us with some information on how to make this happen.
Adding a four-link suspension is something that can be done in a home shop provided the person doing the installation understands the basics of how it works. Zimmerman offers some advice for anybody who wants to try and add a four-link to their car that will help make the process easier and ensure the suspension will work correctly.
“Before someone even starts this project they need to look at the four-link bar length for the build. You don’t want to go to long or too short because that will affect the leverage points with the car. The next thing to keep in mind is having everything jigged; it’s important for everything to be straight as it goes in the car because if it’s not, it will affect how everything works. You also need to know where you want the ride height and the bracket placement. If you don’t take the actual ride height of the car into account when you’re putting the four-link brackets in you can be at a point where you won’t have any adjustment available.”
Zimmerman and Team Z Motorsports have developed a four-link kit that makes building your own rear suspension at home a less daunting task. The move into the DIY market for Team Z came from their huge workload and not having enough time in the day to get cars done. To alleviate this issue Zimmerman decided to sell these four-link kits so people could build cars at home or have their shop of choice use the parts.
When Team Z designed these brackets they wanted to be sure they were easy to use and full of adjustability. The brackets will work with big or small tire cars, so the amount of anti-squat needed was taken into consideration as they were created.
“All of the big chassis builders out there have a highly adjustable set of front 4-link brackets, but it can be a challenge to adjust them. You have to pull several bolts out, make the adjustment, put the bolts back in, and if you’re off on the adjustment you have to repeat this time-consuming process. We took our small-tooth incremental adjusters and built that into a forward 4-link bracket. You can move it up or down about a hundred-thousandth of an inch at a time. There are thousands of different instant-centers available for adjustment with these brackets,” Zimmerman explains.
Installing your own four-link can be done with the correct planning and parts. Team Z Motorsports makes the process even easier with their four-link kit that comes in different configurations based on your application and it includes all the parts to finish the job right the first time.
