No lube needed for the GSF/RCF bushings! They are rubber same as the one’s that came stock on the IS.

Fyi. Ordered these from Megazip and they said the parts are on backorder until about April. It's still snowing a lot here in Minnesota so I plan to wait.

I did ask Discount Parts Monster to price match and they said no.

I ordered on Friday and got the message today that it's in process and will be shipped soon. I guess my order was one of the last ones.

What's the exact link? Is it worth the upgrade? Especially on a brand new 2019 IS? I hear it's worth it.

I can tell you that the $80 that I spent on the RCF bushings was the best $80 I've spent on this car.
I just looked at my inner tire wear after about 3500 miles post-swap, and I didn't notice abnormal wear on the inner side.
Did you went for an alignment process after installing the new(RCF) bushings?

I did not. The tire is wearing evenly, so I think I don't need one. YMMV.

Whether or not you *need* an alignment after a CAB swap (on any car known to mankind) is dependent on a lot of factors, but the safest bet is to get an alignment. now if your tires are already 75% gone (which is why you might be doing this anyway) then personally I'd just roll the dice and wear the tires all the way out. But if I'm getting new tires, particularly xpensive ones, i'd do the alignment at the same time.

In theory, if your control arm is in the exact same position as when you install the new bushing (meaning both bushings locate the control arm identically and are of the same dimensions), then theoretically you should not need an alignment. But that's impossible to know without checking. Some shops offer free alignment checks so you can at LEAST do that.

If your car drives exactly the same after a bushing change, no noticeable wandering, pulling or off centeredness, then chances are the effect of the bushings wasn't significant, if any.

But you can see where results are all over the map with this. There's no rule. It comes down to how the person at the factory aligned your car vs. the old bushings vs. the new bushings.

Bottomline, I'm just trying to save time spent in the shop and asking here based on everyone's experience. I guess I'll have a different one so will just drive the car. If it noticeably starts pulling to any side then I will know it needs an alignment.
