Aluminum sub frame bushings

[Bluto]

What are the drawbacks to solid aluminum sub frame bushings?

I am trying to get the specs, and I know a guy that will make them for me.

Are they a bad idea?

The positives are the sharper transient response and steering accuracy. The negatives are the additional noise and vibration in the passenger compartment.

If you want better control, but less vibration, I'd check out the rear Gen III SHO subframe bushings. It's a full design, and there's rubber. Torrie quoted me 47 shipped I think for all 4.

Sho91mtx .These will fit a 92 ?

 

[SHOZ123]

Yes they will fit. Make sure you get the rear bushings as the fronts are the same sorry design used for years.

FWIW, I just removed my delrin subframe bushings and replaced them with the police bushings. My car is MUCH more enjoyable to drive now that all the motor NVH is gone. It's so smooth now, you can be revving along at 4500 RPM and think it's 2500.

Honestly, I didn't notice that much of an increase in noise or vibration after installing aluminum bushings. Only at high RPM's.

You know, I didn't either, but I think the reason was that my old bushings were SO trashed that anything would have been an improvement.

I've driven Deaconblue's car with the police bushings, and the reflexes seemed slowed compared to mine with the delrin.

Dave, are you getting old?

I don't own a SHO - why am I even here?

 

[Bluto]

Thanks for all the input.
I think if I can get the specs, I will have some made.

**** he is willing to do it for free.

Cincy tells me they have been discontinuied.

Are there any other suppliers out there?

 

[Dave Kegel]

As a further test, I have temporarliy put the delrin bushings in my daily driver '90. That car is all stock, with a very quiet exhaust. It now has a ton of motor noise, mainly between 3 and 4k RPM. It's as if there's no longer any insulation on the firewall. It's somewhat like when you have part of your exhaust rubbing the chassis somewhere. There's this audible resonance now. It's not intake noise, it's not exhaust noise, it's just... noise.

Maybe I am getting old, don't know. But I can certainly do without them. Perhaps the steering is a bit sharper with them, but I think it's more the "lighter wallet" syndrome than anything tangible.

Dave you need to get the smooooth power of the V8.

I got my solid Al bushings from Jon Best. mailto:[email protected][email protected]</a> .

Also Dave that what you get for cutting up perfectly good bowling balls thumbs_u

This might very well be a stupid question, but if the AL. sub frame bushings translate vibrations so much, would a few layers of dynamat in the driver and passender footwells perhaps help with that?

I jsut go my first SHO, and was seriously thinking that I might want to do the aluminum SFB's. But I'm also considering the gen3's as a happy middle, plus saving a few $$$'s cause I'm almost broke now from the purchase.

 

[Guy Newton]

Who's Torrie? and how do I get hold of him? I had alum bushings in my 92 SHO and don't need the harsh ride, but I do need new bushings for my 89.

I have often wondered the exact same thing. I just haven't tried it yet..

Is your car so slow 'cause your sig weighs it down?

well then I'll be the first to try it, or at least the first to post my results as soon as I get them. Once the suspension group buy has gone thru and I have all my nice new suspension parts, I'll order up some daynamat or find something at the home depot. That is of course if I notice anything I can't live with. I planned on daynamat'ing the floorpan anyway. Perhaps just 2-3 layers in the footwells would insulate the noise or vibrations.
