1987 rx7 fc n/a

I am having trouble finding any info on the pro's and con's of toe steer eliminators. I realize how the "toe-steer" system works (from what I have read on mazdatrix), that the car steers into the turn with its rear wheels after some point, but eliminating that will keep the wheels flat around turns? I'm just trying to make sense of it.

Anyhow, I am not exactly sure, what are the benefits and the negatives? Less traction around corners? More traction? Maybe it's not as simple as that.

Thanks!

I simply love mine, makes the rear feel soo much more predictable.Granted My original DTSS bushings were shot and not allowing factory movement. So I cannot tell you how it compares from a working system to eliminated.

If functioning correctly, the DTSS system allows for higher cornering speed. Rear wheel steering systems are making a comeback on the new 911 GT3, among others.

However, the problem is that the FC's DTSS is activated by cornering load or "lateral G-forces". If you are driving at the limit, the wheels have a slight slip angle. Once the tires lose some traction, the cornering loads decrease and the car wants to spin. The reduced g-forces now disengages the dtss function, lowering rear traction even more. This gives the car a snap-oversteer tendency when driving at the limit.

And many people's DTSS bushings are dead and long past their design life at this point. Replacements are not available at a reasonable price so eliminators are the common alternative.

TLDR: DTSS is inconsistent even if you are really used to it. At the limit, consistent is fast so DTSS gets the boot.

The only CONS I can think of is Cost.
According to Mazda,you can't replace that bushing without replacing the whole spindle assembly..for like 600 bucks..a side.
Now,get a pair of DTSS eliminator bushings(say 50 bucks) and a half a day of work...
...see where I am going here?

yeah, the DTTS is very inconsistent, without the eliminator bushings I would say I prefer my fb live axle setup better. With the eliminator bushings it is one of the best handling trailing arm cars I've driven/owned.

You have to burn out the old bushings off right?

No the DTSS pushes out. preferably with a hydraulic press

yep, or if yours is torn like mine was, a vise and a C-clamp and hammer gets them out as well

Yeah i pulled the hubs off and i'm about to do that method to pull them out because whatever.

For anyone interested, this is what they look like: [IMG][/IMG]
They split apart into like 4 different parts

Glad I stumbled onto this thread. I've been wondering what to do with my FC for a while and this definitely helps.

The explanation of how they cause snap oversteer is helping me make sense of a couple...incidents... I've had while pushing it hard in the twisties.

you can also use a ball joint press(clamp type) and a socket.
It was tedious but I did it.

This is what they look like when pressed in. I ended up buying a 12 ton press from harbor freight for $100 (I figured I might as well since I will be putting in poly bushings I just received, although I know it can be done with a vice). and used the arbors they provided with two hockey pucks wedged in between because i ended up breaking my huge vice trying to push out dtss bushings the first time i tried.

Oh by the way, corksport toe steer eliminators are made out of aluminum and are extremely soft, pressing them in even with a press is stressful because they bend so easily.

Anyways, thats all! Praise the sun!

My car is a low milage one that the DTSS works in. It does feel a bit dicey at times but it has grown on me. It can freak a sensitive driver out.
