Lower control arm bushing replacements
2012 is 250 RWD
I was told that my lower control arm bushings have some play in them and they recommend replacing them. Is there a better option than the stock bushings (part # 48075-30030 and 48076-30030)

Most people use either the FIGS Engineering or RR Racing USRS bushings. I have the FIGS 90 duro bushing and they make the steering and braking feel so much better and also help with inner front tire wear. But being so much stiffer, they do increase noise and vibration up front and feel pretty solid over bumps.
I believe FIGS makes an 80 duro now as well that should be a little softer, but I've never experienced those.

Pretty solid as in bumps are hard and uncomfortable?
and while I have you here you seem pretty knowledgeable is it okay if I keep my 255 40R-18 Sumitomo HTR A/S XL tires on the back and put bf Goodrich comp 2 225 40r18 SL tires on the front?

Are you planning on keeping two different types of tires (A/S in the rears; summer in the fronts) on your IS temporarily until you are able to get a full set of the same type tire? Since you're keeping the same model tires on the same axles, you should be okay as long as you don't try to push the performance envelope of your tires as one end will likely break traction much sooner than the other (assuming tire wear is even throughout all four tires, your A/S rear tires will slip much sooner than your summer tires up front).

The higher durometer LCA bushings feel pretty solid as in providing better feedback on road conditions (instead of a muted feeling). NVH increase is hardly noticeable. If they were solid bushings, it would be a different story.

Well the bf Goodrich comp 2 summer tire will wear faster than the Sumitomo HTR P02... I so if there is no issue with having the XL Sumitomos on the rear and the SL bf Goodrich on the front I was going to replace the 2 fronts now then all 4 next time...
