How long did it take you? Trying to plan my day around this if I do it.

Soft cradle and differential bushings are huge contributors to wheelhop. Yes the frequency of wheelhop is much high because the slip and grip of the tires is happening much quicker that the oscillation of the cradle/diff bushings, but that oscillation is in many cases the initial cause of wheelhop. Beyond that, once wheelhop starts, the cradle and diff are moving around so much that the tires can't physically get traction for long enough to drive out of it. When you limit or eliminate that cradle or differential oscillation from soft bushings, there is less movement to initiate wheelhop, and less oscillation to prolong it. You also have less movement in the links because the entire assembly is moving less. And you get less dynamic rear wheel alignment change, which gives you a more consistent tire contact patch. All of this leads to more traction. The downside is, when you add harder cradle and differential bushings, performance goes up but so does NVH. This means more noise in the driver's compartment. Trailing arms help in a different way. The factory links are made from very thin stamped steel with soft bushings. These links are so flimsy the you can pretty much twist them by hand. Imagine how they move with the amount of torque these cars make... By adding rigidity to the links and firmer bushing, you reduce the link and bushing deflection. This reduces rear spindle rotation as power is applied to the chassis. When the spindle rotates (similar to wheelhop in its speed and frequency) there is spring back due to the rubber bushings. This can cause the tire to load and unload, causing wheelhop. The more solidly you can mount the links, the less spindle rotation and wheelhop there will be. |

1. Cradle bushings 2. Upper/Lower trailing arms 3. Upper control arms I was planing on doing it in that order, although I'm thinking about skipping the cradle bushings. |

Stock lower arms - wheel hop. BMR lower arms - No wheel hop. Easy to install too.

Anytime you remove any major suspension component, in the very least you get an alignment check.

Upgrading from SS to 1LE trailing arms made a similar difference like OP talks about but without the NVH in different modes. (Only change to the arm is the bushing itself).

If it were me (and this is how we normally try to steer people), I'd do upper and lower trailing arms first, upper control arms second, cradle bushings (lock outs) third. The reason being, the trailing arms make a very significant different with little change in NVH. The same with the upper control arms, but that is a heavier link from the factory, so it isn't as crucial. The cradle bushings (lock out kit or replacement bushing) is going to make a more noticeable increase in NVH, but it isn't horrible IMHO. When you get into differential bushings yo will see a big increase in performance, but a very large increase in NVH. Most times we do not recommend much in the diff department unless the user is looking for max performance or noise is not an issue. I hope this helps! Let me know if you need any more help. |
