Poly bushings

This.


Then again I went overboard on the lube for exactly that reason on my Miata. Includes track days in the rain with no problems.

I drive Stock suspension with following exceptions (PN & current Street Price)

Note: Focus was to improve driver/car interface with parts that had excellent reviews. These meet that goal big time, and careful shopping got parts below street Price.

Installation and Alignment done by Texas Track Works Ft. Forth of parts KCA416 & KCA 326. KCA 326 is a difficult install which I left to the pros at TTW--Great shop and way nice crew.
I installed the other components.

> Whiteline Front Camber Bolt Kit (KCA416 - $35.91)
> Whiteline steering rack bushings (KSR210 - $40.32)
> Whiteline rear upper Camber Adjustment Kit (KCA326 - $152.82)
> Whiteline transmission mount insert / Positive Shift Kit (KDT926 - $31.32)
> Whiteline Rear Subframe Mount Inserts (KDT922 - $40.32)

Try these first. I've been pleased with the improved response after the increased negative camber front and rear.
Good luck.

One note on the Whiteline rear upper camber adjustment kit....it's awful to install and adjust camber. A lot of shops hate it.

BUT it's one of the more important bushings for the rear to replace since it's in a crucial location.

A good alternative is using the non-adjustable WL bushing in its place and adjusting rear camber with lower control arms. More money up front, but you may end up paying less for install and alignment. And fewer headaches.

What's the part number for the non-adjustable one?

Thanks!!

When lubricating the bushings what surfaces are the most important? Is it the bushing to control arm or the bushing to the inner metal sleeve?

Lube the crap out of both. To the point when you push the metal sleeve in it forces extra out and when you put both halves into the control arm. It's messy stinky stuff, but it's worth to go overkill.


I had Energy Suspension bushings in my Miata in EVERY CONTROL arm connection and never had a problem.


You can go on Summit or Jegs and buy extra of the sticky lube (hehe), I used a ton of it. People like Keith at Flyin' Miata will also recommend marine grease as well.

I have a box full of whiteline bushings and am trying to decide if I should go through the trouble of installing them or just sell them off. Are they worth the trouble?

I have a somewhat similar setup to brzzee. I have SPC front camber bolts and OEM crash bolts, Whiteline rear subframe bushings, and whiteline rear upper control arm bushings. I also have the TiC stering rack bushing I need to get around to installing. I will tell you that the feedback RCE posted from Myles is spot on. These bushings instill confidance. My suspension butt dyno is not as calibrated at CSG or RCE but I can feel a vast improvement, especially with the rear UCA bushings. Pain in the ass? Definitely. Worth it? Hell yes. I also got a lot out of my RCE yellow springs when I installed them (handling plus a lowered car that loks really nice. lol)

With that being said, it is hard to tell you what to get without knowing goals. Is there something you don't like about the car? If not, why change anything? You could end up making things worse. I love my FRS and how it handles and rides, but then I drive my GFs new to her MR2 spyder that is totally stock with tons of body roll and have a blast as well without the harsher ride of the FRS. I spend more time on this forum reading conversations that I barely understand half the time but it has taught me a lot. Ask specific questions with an end result in mind to get really good feedback. I'd recommend you read through the entire CSG/RCE suspension thread stickied at the top as well as the track questions thread. TONS of invaluable info in there.

Edit: just to add I have had the subframe bushings on for 30k miles and the UCA bushings for 10k and have not had an issues with squeeking. Just use lots of lube.

I've been wondering for a while if WL's grease is fifth wheel grease in unmarked packs.

I still haven't installed my rear upper control arm bushings yet or a couple other things. I'm gonna need to take a day or so, when I get the car out of storage, to finish my suspension finally.

enough with the gibber jabber... are you full time auto-xing? weekend warrior? spirited daily driver?

We aren't asking you what you want the car to feel like or do, we're asking what YOU want to do with it

[stockysnail]

I have all the whiteline bushings and installed all of them myself that didn't require a press. The noise harshness and vibration are minimal. The improvement in response is noticeable and appreciated. I feel like I have a better idea of what the car is doing. I do a little of everything: subdued street driving, spirited street driving, autox, and track days. I did a few drag strip pulls as well but I think I'm not going to do that again as I want to keep my clutch.

It's probably not what you were asking, but I consider the motor mounts, transmission mount, diff mount, and rear subframe mounts to be the driveline bushings. Replacing them makes the car feel so much more solid to drive, smoother ride quality and sharper steadier drivetrain response. The downsides are I can now hear (quiet) transmission gear whine, (really quiet) differential gear whine, and minor vibration from the engine when idling. Handily, all those downsides are more like perks according to my taste. Though the improved drivetrain response means if you mis-shift you Will notice.

Rear diff mount stiffening made my car drive massively better when hitting large bumps, the disruption to straight-ahead acceleration is like one-third that of stock. Rear subframe mount stiffening gives you a much more subtle improvement along the same lines. The motor mounts improve ride quality since the engine doesn't bounce around and they let you chirp second at will. Transmission mount, I admit, doesn't do much aside from locate the gear lever a bit more precisely.

One thing that hasn't gotten much mention is ride quality: stiff suspension bushings don't really effect the feeling of a speedbump for instance, but they do make small bumps more noticeable. Stiff driveline bushings IMPROVE ride quality because the car moves more as one large object so there's less wiggly business happening over bumps.

Perrin have a heim joint for the super awkward front control arm front bushing. Aside from that, just buy the STI arms from japanparts, its so very JDM

Hate to Necro an old thread.... :-)


But I thought I would add my recent experience with a two WhiteLine products. I've had my BRZ for a month now and have run it stock to get the feel for the car. (Love It) But the rearend has always been soft to me and the swaybars as well...


Last week I installed the Whiteline rear subframe bushings with no other changes and the difference in the car was amazing! It feels so more tied together for the lack of a better description... The over all feel is so more responsive without a bunch of noise or harshness, you will hear and feel the difference...


After that successful mod I installed front swaybar bushings. The factory front bushings are a pretty rigid for rubber so I wasn't sure what to expect... The roll is pretty much the same but quickness by which the bar responds is better. I will need more time with these.


The fact that I currently live in West Virginia means I have access to some of the most challenging public roads to drive on! :-) The BRZ does a fine job of straightening them out!
