In the form of new, surprisingly beefier swaybar links.
My old eBay special links kept coming loose and hanging and futzing up my handling. So I got these Moog ones that are a billion times better built. The car handles so much better now that the swaybar is actually doing its job.
I also got a new, free battery today because my less-than-a-year-old one shot craps. Under a load test it dipped to 6 volts under a load of 200 amps and it was rated for 700. Not good.
