tsi_tom Posted May 26, 2015 Report Share Posted May 26, 2015 Does D2 have instructions on setting the preload? I didn't see it in the material. Link to comment Share on other sites More sharing options...
Funky Phil Posted May 26, 2015 Report Share Posted May 26, 2015 preload depends on type of driving. It all depends on amount of available shock travel. Street cars generally should have around 30% strut compression up front and 50% out back. This means if the car was sitting on the ground, 70% of the strut should be visible. So if you see say 80%, you have too much preload. Loosen up the spring. My car is setup with 50%. With out correct preload, it throws your cars balance off. I recommend measuring from a constant point (somewhere that wont change with your spring adjustments) to the top of the spring. then start your adjustments. Say your measurement was 10", Id wind it up an inch and see where that leaves you. Leave you shocks set in the middle of the adjustment window. (16-20 clicks. cant remember if they are 36way or not) When you think all four are set, go for a twisty drive with some 0-60 and hard braking. Once preload is set, then play with shock adjustment. Hope that helps. Link to comment Share on other sites More sharing options...
tsi_tom Posted May 27, 2015 Report Share Posted May 27, 2015 How do you see if the strut is 70% visible? Link to comment Share on other sites More sharing options...

twojayzeestarion Posted May 27, 2015 Report Share Posted May 27, 2015 the d2's instructions say "spring should be tight but still move freely" i also read that if you run more preload than a certein amount on d2's it could damage the strut. dont know how much truth that hold though Link to comment Share on other sites More sharing options...
importwarrior Posted May 27, 2015 Author Report Share Posted May 27, 2015 found this from D2 FAQ http://www.d2racing.com/support/faq/ 3. How do I preload the springs on my coilovers?The springs on your full coilover should already be preloaded out of the box (Always verify this prior to installation). The spring itself should be snug up against the top of the coilover and the locking perches at the bottom should be snug up against the bottom of the spring. The spring should not have any free play or be able to move up or down. Do not crank down on the spring and cause it to compress as this can result in an unpleasant ride quality. * Link to comment Share on other sites More sharing options...
tsi_tom Posted May 27, 2015 Report Share Posted May 27, 2015 I remember reading that in the instructions so why does Phil preload them? Link to comment Share on other sites More sharing options...
importwarrior Posted May 27, 2015 Author Report Share Posted May 27, 2015 a lot of that helps with weight distribution for racing or better balance of the car depending on the type of racing. Link to comment Share on other sites More sharing options...
theboyo19 Posted May 27, 2015 Report Share Posted May 27, 2015 I'll be adjusting mine this weekend, first drift event was nasty, it would load up and snap hard on the transitions. My buddys who have 4+years exp couldn't get it around a single corner without snapping into a spin out haha Link to comment Share on other sites More sharing options...
tsi_tom Posted May 27, 2015 Report Share Posted May 27, 2015 They make a strut for drifting. Are you using the street version? Link to comment Share on other sites More sharing options...
Funky Phil Posted May 28, 2015 Report Share Posted May 28, 2015 (edited) Better weight transfer and dist. They say "can", not "will" Doing a burn out "will" wear your tires outA proper burnout "will" assist in a better launch.Speeding "can" result in a crash. So "can" driving the speed limit. They say not to so they dont have to hear people complain when they do it incorrectly. I want the springs to react sooner to sudden changes and assist the shocks.

tankbob Posted May 30, 2015 Report Share Posted May 30, 2015 From my own understanding preload has a similar effect as running a stiffer spring, only so much preload can be added before the strut should be revalved to handle more load. Link to comment Share on other sites More sharing options...
theboyo19 Posted June 1, 2015 Report Share Posted June 1, 2015 its been a few years since i got em, took em out of my old car that handled fine, somewhere along the way i messed up the preload, i honestly dont know what version i have Link to comment Share on other sites More sharing options...
