DTSS bushing replacement
 

Everybody,
Does anyone make replacement bushings for the DTSS? All I can find are elimator bushings. Also, when it was new, did the system even work? Is it even worth it to look for replacements or should I just go with elimination? Thanks.

Eliminate it and be happy you don't know what it really does. New DTSS sucks and it gets worse with age. The bushings are (in my opinion) the best suspension money I've spent on the FC's I own.

or you could just answer his question

mazda sells it with the arm...

I didn't know anybody sold them, Mazda included. Sorry. (they still suck though)

How does it suck, have you ever driven a car with a replaced bushing and arm.

Lower control arm? Upper control arm? Dare I ask, part number?

Are they #3 in the image at: MazdaPartsCheap image?

what does DTSS really do? is that the system that makes the rear wheels have -1 deg camber when you go hard into a corner??

yep, thats the one, DTSS is codename for super positive camber cornering bushing

Your outside rear wheel toes out, IIRC

So the general consensus is just to eliminate the thing? If I do that, does the system just become extra weight? If it does, could I just remove the system, eliminating weight and upgrading the suspension? Thanks

Here we go again...
 

I don't understand why so many Mazda fans and owners think that they are smarter than the Mazda engineers who designed the cars we all love.

About 2-3 time per year, someone asks this question and all the people who don't know answer the question first. So next time someone searches, all he finds are opinions, shaped by what someone else heard, about somone elses opinion based on what they heard, based on what 'real racers do'.

So all they find is Bull, so they ask the question in hopes of finding a good answer. And the cycle starts again.

The system was a breakthrough in sportscar suspension design when it was developed. Now, however, your car is 22 years old and EVERYTHING made of rubber is worn out.

If your car is not behaving right, it is not just the DTSS that is worn; everything made of rubber is worn. If you have worn shocks, saggy springs and all your bushings are shot, you don't need to start with the DTSS. You need to fix your car.

Start with the shocks.
Check the spring heights (This is a good time for some Eibach replacements).
Install a complete polyurethane bushing replacement kit.
Get a good quality alignment, *NOT* an alignment at the tire chain where they have the youngest cheapest techs and intend to give you just enough alignment to get you to leave them with your money.

Your car will drive completely different at this point.

Then, and only then should you consider f**kng with the basic suspension geometry of the car.

And if you don't have a very keen working knowledge of things like trailing brake oversteer and throttle-lift oversteer and trailing throttle oversteer, you probably need to learn to drive your car. Otherwise you are not a good enough track driver to even understand how the DTSS eliminators are going to affect the real life handling of your car.

Here is a pretty good thread that covers the topic.

Lots of BS early on then some detailed information later in the thread. You can digest this thouroghly, or you can just accumulate more bad advice from people who heard something from someone who heard something.

Good luck.

whats the part #s for the bushings and the rod

Are you referencing my question about the given image or raksj?

jack, could you tell me if the image I found references the DTSS bushings as part #3?

actually it's dynamic tracking suspension system or something like that and it changes toe, not camber.

NO, the bushing itself is on the triaxle hub carrier, which is not in that picture

DTSS, when working properly is a fun ride. My first fc had the DTSS that worked great, and I loved it. But on the other cars I have owned the dtss never worked, and I actually miss it every once in awhile.

Is the triaxle hub part #3 in this image? (Note: This is a different image even though I'm asking about #3 again.)

I would have to say no, as that pic is for a 929. But if you want a generic general answer, then yes it is.

nicely put.

Wow, I did a search for "DTSS PIC" and look what I found in the first thread!

EDIT: BTW, there is also another current thread discussing this...

Good call on the pictures Tray. Mazda doesn't sell the DTSS bushing directly, you have to buy a whole new hub as shown below. I've heard Mazda didn't feel people could properly press in a "compressable bushing" without damaging it.

Than Que.

Than Que berry much.

Is there someone out there w/ enough skill to fab replacements? When I upgrade my suspension, I would like to try out DTSS that works before I chose whether or not to eliminate it. Thanks much

Hi!

If there are no replacement bushing available, is it possible to make some at home? So... take a poly urethane block (with an adequate stiffness) and a lathe -> new dtss bushings?

Just an idea, or is there something super special about the mazda dtss rubber bushing that you could not build bushings "at home"?

Daniel

so what is all involed in fixing the DTSS? is the toe elimater better then broken DTSS? i thought of putting the toe elimater on then fixing the DtTSS, but i think my rear bearing are going not sure yet.
