ive took everything loose and i still have no drop and it is a 9in shock what to do

[junebug]

is the rearend hitting the underrslung.....if the shock and spring is loose on lr and its still not down to the underslung then that means that u have a bind in the birdcage somewhere

[junebug]

do these cars even have underslung bars? if not then the lr should fall completely outta the car with the spring and shock unhooked.....there is definately something binding up if thats not the case

[dirttrackrocker]

I don't think lightnings have an under rail.. Theres definately a bind somewhere...

Do you run a dampner shock like a 9010 or something like that?

[bluemod]

yes i do run a 90/10 damper is this bad or good that i do

Measure your rear end to frame rail at ride height. Put jack stands under frame and remove rear shocks and springs. Put jack under the middle of rear end and jack it up to your ride height. Move the rear end up and down on the right rear and left rear just like it travels as roll steer. If nothing is binding there check as you put your springs and shocks back on. Make sure to check your left rear shock drop. With a 9in shock you still may need a 1in or 2in extenion on your shock but make sure it does not bottom out when it drops off the bars. There is a sweet spot there. As for springs with a metric clip I would start out with 800LF 750 OR 700 RF 200 LR 175 RR. On the scales around 57.5 to 58 rear 52.5 53 left 49 49.5 cross on dry slick 75 or 80 lbs LR maybe even up to 120 or 130 LR. Good luck

thanks ill try this after work and see whats going on

[bluemod]

one more thing are these %s with or with out driver and lr shock should it be mounted on inside top frame rail or out side top rail i have to diffrent mounts . Ones angled in toward center line. others outside up and down. and these are coilovers also if that matters

[washeduptoo]

One time we mounted the 9010 in the wrong hole on tower bracket(too far to the back) and it wouldn't let rear end drop all the way as shock was extended out all the way. Good luck and I would still call Lighnting chassis or email to get basic set up.

Get rid of the 90/10. If you start getting wheel hop under braking put it back on.

[bluemod]

is it better to just not use the 90/10 advantages or disadvantages

[dirttrackrocker]

It's a feel thing, some guys like it, some don't. But I would ditch it and see if thats whats keeping you from getting enough LR drop.

[bluemod]

thanks im going to try this and see what it does saterday night and ill get back to you all thanks
