Got mine put on this morning. Took him like 15min total. I thought you guys were full of crap about feeling a difference right away, but I can tell. The steering feels slightly "crisper" and you can feel a little more of the road feedback. I likey...

How is vibration, especially steering wheel? I'm guessing zero since its not solid like RR?

Thanks. I switched bushings in a previous car and I hated the steering wheel vibration, especially while driving. IMO, it wasn't worth the trade off. However, that was with poly based bushings, similar to RR. I really need to find someone local that's done this to test drive.

Pretty sure you wont be disappointed in the upgrade, especially what everyone says about the tire wear before the swap.

@EvilJoker You say slightly crisper and a little more road feedback. It’s good that you noticed the difference right away cause I’m kind of at the limit of how my car feels numb and not communicative to me at speed. I’m not quite sure at times where the steering wheel is pointed and to me, those few degrees of steering input matter, especially on back roads. This is even while I’m in Sport+.
Not sure if I should jump to RR-Racing or jus the RCF/GSF bushings. I realize the pros and cons of both, but ehhhhh, the numbness and isolated feeling is scary at times. Leaning towards RR-Racing at the moment. Any suggestions?

Rationale: The RRRacing bushings have been available for some time. While those that have installed it have commented on the feedback from the steering and vehicle, for some this has been a negative situation. The RCF/GSF bushings have been a newly discovered direct swap and upgrade to the IS bushings, and there have been similar comments about the feedback of the steering and vehicle, but none have put them in a negative light yet. Considering the RCF/GSF bushings are roughly 25% the cost of the RRRacing bushings, the choice, IMO, is clear. I would install the RCF/GSF bushings, and if still not happy with the performance of the vehicle, then upgrade to the RRRacing bushings. The reality is one product is rubber, the other is poly, either material with it's own benefits and drawbacks. The poly will need periodic lubrication to stop any noise it may create, and the rubber will have a shelf life compared to the poly which will likely outlive our grandchildren. For road use the RCF/GSF bushings, once again IMO, is more than enough to correct the issues with the IS front suspension complaints.

I’ve had the GSF/RCF bushings on for about 4 months and have been very satisfied and happy with the difference. Naturally I’m used to the feel now so I no longer feel a difference, but time will tell if my inner tire wear gets a little better.

The first drive after the bushing swap was almost like night and day.....and if NVH has increased, I can't tell.
