    Pro tip: use spring stabilizers in the rear when drag racing a fwd car to prevent weight transfer to the rear which helps limit wheel slip/hop.

Even with the car completely unladen, the rear is still way too soft and loose. You can simply prove this by pressing on the rear bumper and the car will squat down before you've finished transferring all your weight to your hands. Why Suzuki put such stupidly weak springs and shocks in the rear is beyond me. It's bothered me from day one. I've always planned on building my SX4 into a little overland expedition vehicle, which it's just about finished, but the fact that it can't handle any sort of cargo in the back will not do for obvious reasons.
    Maybe it's a US market thing. I've taken loads including flat packed MDF kitchen cabinets and bricks to our beach place and the Aus spec handles them quite well.

    Doesn't really create any lift, just prevents the rear from sagging and helps the weaker coils from collapsing so easily. It definitely sits higher than before when there's weight in the car, I wouldn't really say it does when the car is unloaded though. But just creating a slightly higher spring rate in the rear is win/win in so many ways. Less squat when taking off and when shifting, more load capacity, more responsive rear in general is a good thing in my mind.

    I had Koni yellows set to full hard as well as lowering springs and a custom 28mm sway bar in the rear of my 850 R paired with the stock 21mm front bar and konis to full soft with lowering springs in the front. So I naturally like a tight rear that rotates nicely and a softer front end that digs into corners and prevents under steer.

    I'll let you insert that's what she saids where you see fit.

    Agreed. I also like the balance in handling of having a tight rear in a FWD-biased chassis.

    I'll tell you when I do it! I was going to do it Thursday but looks like I might have some free time tonight. We'll see.

    There also were small diameter coil springs that fit over shocks. If installed at ride height or slightly over, they don't raise the car just stiffen it. Most conventional US cars had rear shocks at crazy angles trying to control spring wrap up or trying to be sway bars, so their weight carrying efflect was limited. The SX4's vertical shocks would seem to be ideal for them. I don't know but have always heard that the stabilizers ride down the spring and can pop out if you get a little air over RR tracks.

    I've seen those too, but you're pretty much stuck with carefully measuring and ordering the right length. And they're also supposed to be a shock killer. The spring spacers I installed are nice and tight even at full droop and I made sure to install them on opposite sides and close together so you get the least amount of spring warp possible.
