b'TECH TIP PAGE Tech Tip 5A: Why do we utilize a Torque Arm for Autocross & 3-Links for most Road Course applications?Time, or lack thereof. As much as 3-links are great at being tunable, there just isnt a whole lot of tuning time between rounds when Autocrossing.A pro of the Torque Arm suspensions is that they are simple & easy to set up. Torque Arms dont require any tuning, because other than length, they are basically non-adjustable. The key is choosing the right length of arm, because in most cases, the length cant be changed.Shorter arms provide higher Anti-Squat, more loading of the rear tires on initial & early accelerationless on later accelerationand even less on corner entry under hard braking, unless it is decoupled. A longer Torque Arm simply reverses these characteristics.A good road race & track car rule of thumb is for the Torque Arm pick up point to be under the Cars CG55 to 60 in most 108 WB cars. But for Autocross, we want a shorter arm, due to the lower corner speeds. We have found a 45-47 Torque Arm lengths is the sweet spot. Shorter lengths add more forward bite (more grip on initial acceleration) which is critical for coming off slower corners. For the higher speed corners of road courses, with higher corner exit speeds, longer arms work better. With 3-Links, we can tune the Instant Center to form this longer or shorter arm. With Torque Arms you need to pick your length based on priority.Tech Tip 6A: Panhard Bar Versus Watts Link. Both have pros & cons. Our Quik-Tune Watts Link System is the quickest, easiest to adjust and handles equal both directions. We 100% recommend it for autocross, because you have very little time in between runs & may have two courses that favor left or right hand corners differently.For Road Racing/Track Day Cars it is more of a choice between quick versus optimum tuning. A panhard bar (PHB) is more work. First you need to adjust the left & right side PHB heights to achieve equal handling on left & right corners. The axle mount side will be lower than the frame side when you achieve this. We start the axle side 1/2" lower & tune.At the track, assuming you have adjusters on both sides, you can tune each side of the PHB mounting points to favor left or right corners. How? If you lower the driver side of the PHB, you will see more rear grip on RH corners & less rear grip on LH corners. If you lower the passenger side of the PHB, you will see more rear grip on LH corners & less rear grip on RH corners. Raising the PHB on those same sides has the opposite effect.We can tune a double adjustable PHB to favor the 7-9 left or right hand corners of a road course & have faster lap times, but it is more work. A Watts Link will always handle equal both directions. Our Quik-Tune Watts is super quick & easy to adjust. Your call.The Track-Warrior rear frame rails were designed to mount narrower, so the shocks could mount wider. For this reason, we cannot make a panhard bar package fit in Track-Warrior frame rails. We can in the Race-Warrior & factory frame rails because they are set wide.134'
