    So lately there has been a ton of questions regarding which drop is best for this, which is best of that. Below are 6 articles that will go through and explain how performance suspension tuning is done.

    Making It Stick Part 1: Four basic steps to better handling

    Making It Stick Part 2: Four more steps to better handling

    Making It Stick Part 3: It's all in the geometry

    Making It Stick Part 4: More lessons in suspension geometry

    Making It Stick Part 5: Damper fundamentals

    Making It Stick Part 6: More advanced dampers


    As far as putting a performance drop on our truck, we are still lacking for aftermarket support in many of these fields. But on the contrary Toyota did a lot better then most give credit for in designing our current suspension. The geometry was so precisely dialed in, that any changes we do will upset that. Now there is always the give/take when putting a new mod on, so while we'll make one aspect better, we are sacrificing in another that may or may not be directly related.

    Feel free to post the pros and cons of your drop. I will add those to this post for future reference. :top:

    great read! djm=bump steer , if there was a way to raise the rack and pinion about an inch this would make the djm really shine

    A steering dampener could help with bumpsteer too...

    But I don't know who makes one?

    Waiting to install S.S. Performance drop. Went with coils, leafs, sway bars, QA1... was wondering if anyone has had any trouble with using stock struts, or any suggestions on who makes a performance strut to compensate for the drop?

    There is no aftermarket strut available for our trucks. Had SS coils on my truck for 4 years now with no issues

    It's mean to use the stock struts, no aftermarket ones yet.
