    When I do the disc brake conversion I get the option of the drop spindle.

    What are the true advantages of going with the drop spindle?

    I'm looking for a picture of a skylark with a dropped spindle in front and stock height in the rear.

    Will stock height front shocks still work? my kyb are brand new.

    The short answer- It depends on what your looking to accomplish with your car.

    Drop spindles are a great way to help correct the geometry angles of our front ends to help improve handling. Most aftermarket drop spindles relocate the upper ball joint to create a “taller” spindle, while still offering lower ride height in the process. I personally have not run a drop spindles without buying aftermarket control arms, but I know others on here have. I don’t see why you wouldn’t be able to run your current shock setup, but I would call the manufacturer of the spindle your considering to confirm. If your just looking for a lower ride height and more aggressive stance, the most cost effective way would be a good lowering spring.

    I actually really like the stance of my car. But I'm doing the 20210307_112030.jpg disc brake conversion regardless. So if the drop spindle will improve handling then I'll probably go that route. But I'd like to see a picture first of what it would look like if anybody has one.

    You will more than likely have to run taller ball joints (at least on the upper control arm) to accommodate the increased height of the drop spindle.

    Your car has a great stance! In my experience, a two inch drop spindles doesn’t actually lower the car a full two inches. It will lower around a 1.5”. Are you running manifolds or headers? Headers will almost certainly bottom out at times under suspension load.

    I can tell you about this I did it car is lower with heavy rate springs, boxed rear control arms, large sway bars front and back,
    I used 77 Camaro spindles up front with disc brakes, adjustable shocks I think I used Koni there I also have poly bushings.

    235-60-15 up front and 275-60-15 on rear I used TA radials at the time I did this in 1990 it was called HO Racing set up
    The car does handle very well I mean real good little stiffer now about like my 92 GT Mustang conv.

    This set up also kept my headers from Ever hitting the ground again.

    I would not lower the car with full length headers. Convert the front to negative camber gain. That will cut down on understeer and make it handle. You can do that with tall ball joints and aftermarket tubular upper control arms.
