Installed rear lower control arm bushings today and so far it seems to have tightened the car up and eliminated the luxury car neutral on center feel.
First piece of advice.... Take the stock brackets off and bring to a auto machine shop. I had access to a press and the stock bushing metal sleeves just mushroomed. They are also fluid fill and make a mess if you decide to push the rubber out ! Installation was easy with a jack and jack-stands, no force required. I will wait a week to see if an alignment is needed. I fully tightened the nut on the bushing after lowering the car

 

nice. what year RC350 do you have?

 

2015 rc350 awd f

 

My old 2015's suspension/response was mushy as hell too. Glad that the Figs kit can fix it. One of the major reasons I picked up a new 2019 RC is the suspension is majorly improved. Now it drives like a true sportscar
