^^^^They do a LOT more than that. Handling is greatly improved and brake dive is greatly reduced. There is also more NVH. However the NVH varies with the choice of bushing material. I had the standard ones from RRR and the NVH was a bit more noticeable in my ISF, it was certainly easy to live with considering the improvements.

I read the threads posted earlier in the thread and ended up going with the Figs. My concern was the tire wear issue as well as trying to improve steering feel and reducing brake dive.
Most reviews I read reported negligible NVH from the Figs. I'll report back once I install it myself along with the Swift springs I have on order.

"The reason you don't have to deal with load adjustments on those is that there is nothing on them to prevent Axial movements from the control arm. When you experience hard braking, the axial movement of the control arm leads to changes in toe that wear your tires. The RR Racing USRS has a thrust washer design that prevents the axial movement. These preload measures are easy and only require a feeler gauge."
Figs is set up like the OEM RCF LCA bushings...just a more firm PU. both Figs and the RCF bushings perform better than the stock or OEM bushings on the IS500. I went with RR-Racing USRS for the reason above.
