Hey Steve, have you installed the redesigned Whiteline rear subframe bushings yet? Curious to hear how you feel they compare to the original design. I am debating between them and the street AKG right now. I have the Defiv lockdown kit and mFactory LSD currently.

Looks like you installed the left guide arm on the right?

Could just be the picture but the guide arm is meant to have the curve facing down if I'm correct?

RSFB still look like the day I put them in. I actually had to lower the rear part of the subframe to get my rear differential bushing changed and took one of the RSFBs out while I was in there to examine it...looked great.

Here's a couple pics.

I noticed the Strongflex ones do not come with the metal washer that goes between the car and the bush.

They are also 1 piece instead of 2.

Do the Polyurethane bushings require additional maintenance over time? As in you would need to regrease them every couple of years otherwise they start making noise?

Nope. Not the subframe bushings

How does one determine which way is 'UP' for the PU RSF bushings?

Necroing this post but...

Thx for the advice! You are correct, you can get enough room without dropping the muffler or disconnecting brake lines if you have two jacks and pay attention. I am jealous of those who are getting the bushing to slide out with heat and the cars weight. Tried it. HAve one rear about 1" out. Won't go more. I am using a heat gun not propane torch...you mentioned "goo"...are you literally melting the bushing? Maybe that's my problem... I may just order the tool tomorrow ($300). Seems like HP Autosport has them "backordered" so I am not sure I can even rent a set. Ironically, I borrow a friends $500 assortment bushing tool set...nothing would work for our cars. Amazing.

I remember having to get the bushing really warm. The bushing itself doesn't have an outer sleeve or anything so it was more about getting the bushing pliable than expanding the subframe with the heat. I'd try concentrating the heat on the bushing with the heat gun or using a torch.

OK. I'll try that tomorrow night. I was focusing more on the metal.

I just noticed you are in the Seattle area. I am in Kingston! Maybe I should hire you to come supervise this job...

Whew...job done. With the tool it is straightforward, but you do have to disconnect the brake lines so I'll need to bleed the rear brakes tomorrow. Job also caused me to notice another issue...looks like my differential has a minor seal leak. Ug.

First drive was good. No increase in NVH but nothing dramatically different in feel either. I'll know tomorrow on my drive to work as there is a set of RR tracks where I could really notice the side-to-side shimmy with the stock bushings...

No shimmy. Feels a bit more planted, but TBH, not dramatically so. I'll get a better chance to evaluate at the HPDE on the 25th.

HPDE was great! No issues with the rear. Felt very planted. Glad I did the upgrade.
