Rookie racers think they need the links in the same holes, or location, on each side.Not true. The sway bar works the same on left & right hand corners regardless of any arm length differences on the opposing sides. Same front or rear. Most people think a front sway bar with two holes in arms has two rates. But you can split the holes with one link. The actual bar size & rate you receive in your package is tailored by your cars weight.For example ONLY, if Clients AutoX-Star car ends up around 3400#, we utilize our 1.25 x 34 x .250 Wall Sway BarIt is a 3-piece 4130 chromoly splined sway bar from Speedway Engineering. The sway bar mounts under the 34 wide OEM frame & the sway bar arms are under the frame as well. This adds inner tire clearance without causing any issues.With our 45 steel sway bar arms the 9.25 long holes provide a 830# rate & the 8.25 short holes provide a 1044# rate. If you put one link in a short hole & the other in a long hole, you split the rate & have 937#. The lower the rate, the more grip up front & less in the rear. Conversely, the higher the rate, the more rear grip & less in front.Ron engineered this setup to run the softest 830# rate on tight autocross coursesthe 937# rate at average autocross coursesand the stiffest rate of 1044# for large, Nationals size autocross courses. If youre at a track and need more rear grip throughout most corners, adjusting your front sway bar stiffer adds rear tire grip. Just the opposite if you find you need more front tire gripsimply adjust the front sway bar to be softer.Many racers automatically run the softest rate on super tight courses & the higher rates on courses with more open radiusand higher speedcorners. And its quick & easy to adjust if you find you need a little more.One key thing: When you are splitting holes, you dont want to accidentally put any preload in the suspension. No pit surface large enough for a car is truly flat. So you do want to find a spot where when you unbolt one link, the sway bar arm doesnt spring away. Ideally, you want the bolt to come out easily, with no bind. Then adjust the link length to bolt in the other hole, without binding as well. Just another tuning tip to get you dialed in optimally on race day. 174'
