Smith adds, вЂњThis spring compression baseline is crucial at placing stored energy in the front suspension movement. You can find extensive tech sheets for spring selection within the QA1 technical pages of the website. вЂњWhether it be a stock-style spring, one of our stock mount coilover systems, or a true custom mount coilover shock system, your front springs should be compressed by the weight of the car at 30-35-percent of that springвЂ™s overall length,вЂќ Smith explains.ДЄs a starting point, QA1 offers a wealth of charts to select coil springs based on your car's four-corner weights and shock angles. Stored Energy In Your Front Springs Is The Key Starting PointД«efore we get into shock tuning, letвЂ™s look at the springs that a racer installs on their front suspension. With input from Steve Smith, the Lead Technical Writer for QA1 High Performance Suspension and Driveline, we will concentrate on your front suspension and provide some in-depth explanation of shock and spring applications, along with their tuning. Mastering the shocks and springs is as definitive as putting the best racing engine together yet missing on the tuneup. Most drag racing and performance suspensions include some shape or size of adjustable shocks as the norm.

With the help of the gang at QA1, weвЂ™ll work to take some of that trial and error out of the equation to get you in the ballpark and on your way to quicker, more consistent launches. After all, thatвЂ™s where the drive tires are, right? In reality, though,В the rear suspension works in direct concert with the front shocks and springs, and whatвЂ™s going on up front can make or break you, whether youвЂ™re a heads-up or bracket racer.В At the end of the day, itвЂ™s all about transferring weight adequately and efficiently, and while itвЂ™s not rocket science, thereвЂ™s much to be learned through trial and error to balance the setup. He has guys riding around on bikes with less than 2' of trail and they love them.Д«uilding one yourself is not that big of an endeavor if your handy.Drag racing newcomers often fall prey to the ideology that performance and consistency both begin and end with the rear suspension configuration and setup. He will take all the measurements that you give him and build it custom to your bike. He does awsome work and his narrow version is tight and kickass. Then you have Jaxons ISG fork which is an improved version of the Harmon spirder. Gambler makes girders buy I don't know how well that company is operating since it change of ownership. Some of the nicest looking girders are made by George Counes at Spartan Frameworks,$2,100 raw. With a little time on the drawing board you might be able to find a girder off the shelf that will work for the trail numbers you want. On my bike the rake is at 42 and the main leg of my girder is right around 43.

If you have flop then you want to reduce trail and off the shelf girders have little room to shorten the links. Changing the connecting links only does minor changes in the trail numbers. The connecting links are typically around 4.25' long. In my personal opinion a good functioning girder should be custom built for a specific bike.
