    I just installed a Total chaos +2 kit, although I think this should apply to anyone with adjustable front coilovers..

    My rear end is up quite a bit higher as it sits right now, so I would like to get a little more height out of the front end.

    I have 600 lb springs right now, the adjusters are cranked down about an inch... How much more can I crank them down before the coils lose performance?

    I like how the ride is now, so don't really want to up spring rate but is cranking them down to a certain point essentially doing the same thing?

    I have a front recovery bar / high clearance hitch from mobtown, probably weighs no more than 70lbs or so.

    If you're trying to compensate for additional weight you'd be better off swapping to a higher spring rate than cranking the coils down IMO.

    What coilovers are you using? They should have mentioned what the maximum amount of preload is.

    What rate spring should you run with all steel plate bumper, skids, and 10K steel cable winch?

    Definitely not 600.

    I went from 650 to 600 because I have no added weight and didn't appreciate the stiffer ride.

    What will happen with a 600 spring? Thanks for the info.

    It will be soft and bottom out fairly easily. You'll have to crank the adjusters down farther than normal to regain height.

    I guess that would be my question, what is considered "normal" amount, is say 3" cranked down pretty safe to say that won't mess with performance too much?

    I honestly don't know the exact model of coil overs, they are king remote reservoir that come with the total chaos +2 kit

    You want to make sure you are not at coil bind when fully compressed. But if you like the ride crank em a bit. If you find you are bottoming out to easy / to mushy of a ride, up your springrate.

    Between 1" and 2" of preload in the front of a Tacoma is good. Much more than 2" and you'll run the spring coil bind (sometimes less depending on what exact shock you have). What shocks do you have (brand and part number)?

    Preload is how much you compress the spring from it's free length before setting the truck down on it's weight.

    If it's too soft you have a valving problem.

    Im going to set them at 1.5'' for now... guess I will go from there to determine how the ride is and what not... I cranked them down 2'' and that actually was too much as the upper uniball cup was hitting the high mis alignment spacer while the truck was sitting on all four wheels. Guess that is the limiting factor with how much height I can get out of the front end.
