RSFB DIY - Solid Aluminum bushings
I plan to replace the RSFB with solid aluminum bushings. Based on some reading from this forum, for the Whiteline two piece bushing replacement, I don't need to drop the entire subframe. Each end can be lowered enough to press out the old ones and press in the new ones.
However, for solid aluminum bushings, someone has mentioned that I might have to drop the entire subframe because the solid bushings need to be pressed in from the top. From looking at the bushings, it doesn't seem to be the case. But I want to confirm with you guys who have done solid aluminum bushing replacements. Please let me know if I have to drop the entire subframe to install the aluminum bushings. Thanks |

I did Whiteline bushing by just lowering the subframe. I thought I was careful to not put too much stress on the short brake lines that connect over the subframe but a couple years later I noticed they were leaking and had to drop the subframe to replace them. I'd say drop the subframe.

Disconnecting and reconnecting the rear brakes line and bleeding the brakes are easier than dropping the subframe. If I do the bushing swap without dropping the subframe, I’d rather not.
It’s good to know that you can install white line bushings without dropping the subframe. I’d definitely consider that. Thanks |

Currently if anyone has experienced both solid aluminum and polyurethane bushings. Can you feel the difference?

I’m considering Whiteline bushings instead of aluminum given that I don’t need to drop the subframe. However, if installing aluminum bushings doesn’t require dropping the subframe, obviously I prefer aluminum. Still waiting for response from this who have done aluminum bushings installation.

On a separate note, the TC Kline coilovers came in yesterday. I plan to do the bushings, 1M front&rear control arms and coilovers installation all at the same time. I’m getting some help from a track buddy for the installation. Ordering the control arms next.

Install them as designed so you don't have any fitment issues. Putting the alum. bushings in the freezer overnight can result in them just drop right in without much effort. The bushing inserts can get you 70-80% there, not a bad upgrade for much less effort.

Install wasn't hard, I used a kit from ebay and was easy to press in, no need to freeze etc if the alignment is correct - it should slide in without much fuss. I did have to lower the subframe / disconnect brake lines / bleed etc to do it correctly and without worry of ripping out my brake lines. |

I didn't notice any new noises stemming from the alum vs poly vs stock rsfb; just less movement in the subframe, and more direct feel with the suspension components.
