poly vs. stock control arm bushings

viggen ball joints are shot of course, and im sure the bushings are tired at 167k.

the question is, being a daily driver, and not used as a performance car, is it worth the extra 100 bucks to have poly bushings?

suspension is already konis/eibachs/poly front arb bushings/poly steering bushings.

idea is to keep comfort, as i live in a city and its very bumpy, and i use it for long ski trips all winter.

I'm facing the same decision, except I already have the bushings. I wouldn't think that the large outboard bushings would affect ride/noise. As for the subframe and body connection(s), I'm leaving them stock. They're smaller and should not allow that much movement, compared to stock, but will still isolate mechanical and road "noise". My 2c

I had poly control arm bushings and all the other typical suspension mods. I put about 45k on the poly control arms and never found it to be anything too extreme for a DD(which it was for most of it's life).

Hey Jameson (or anybody else), can the control arms be bought without the stock bushings?

It actually is a necessary decision, and without any evidence you have brought nothing to the table.

Poly is not always better

Well if you're going to pout about it...

I've had the poly for 3 years, and I think they are worth the upgrade.
I too take long trips (i.e. 12 hour trips once yearly and 4-5 hour trips once or twice monthly) with koni's (set at full firm) and the whole shebang of poly bushings. I have no complaints at all. There is a much tighter steering feel, and it wanders less on crowned/ rutted roads. Like I said: It is a non-decision. Get them and you will be happy.

GS gives you the option of stock bushings, or the poly ones.

I daily drive my car in and around boston. I have every poly bushing offered by GS and have noticed no changes in ride quality. Put them in. They are cheaper and more durable than stock. The one thing I did notice was crisper turn in and less slop. That being said it has not added any harshness or extra road vibration.

so you did notice changes in the ride quality... they were just positive changes.

Yes, my bad. No changes in terms of ill effects.

i have both stanchion arm poly bushs, lca bush,tie rod bushes they didnt effect my daily driving i think they inprovved it.

a little off topic but if your into ride quality dont get low profile tires. theres a big difference between 16x6.5 205/55/16 and 17x8 235/40/17 in ride quality. i feel bumps i didnt feel before just by swaping tires.


and one more thing to mention. you know the stock bushes can got to 167k on the vig. does anyone have any long term use with poly bushes? like 100k miles?

If the stock can go 167k with only the ball joints failing poly should technically last longer

I doubt anyone has done mileage that significant since the bushings haven't been out more than 3ish years or so

Yeah, but you don't look as kuel with 16" wheels!

I'm a 16" fan too, from a view point of ride, acceleration, and pothole protection. But, most people opt for 17's, or even 18's (good gawd) now, because it's trendy.

Word of warning: there were some posts in another forum by a guy who ordered arms from GS. They guaranteed they were OEM before he ordered, then they sent him Scantech. He had to argue with them long and hard to get a refund and he still got stuck for some shipping.

I'd order the poly from them if you like, but get the arms elsewhere.

There's definitely better steering feel with the poly control arm bushings, and less of the wandering feeling on rough roads. But...I replaced all the subframe and steering bushings at the same time, so I can't isolate a specific value for the control arm ones

So...

Your question about whether it makes enough of a difference, especially on a car you're planning to sell, is pretty valid....
