So that's my current problem at high speeds. i wasn't sure if it was my LSD or bad shocks, although i'm sure the stock shocks are gone. When i first bought by car, i drove it home at 55 mph on the highway with bad tires and that thing was sliding all over the place. if i even thought about going over 55, the car would skid out of control.
will a suspension overhaul help any, or do i need to do this DTSS overhaul and limit the motion. Seems doubtful that mazda would have designed a suspenion with 2 degrees of freedom, and by doing this you are completely restricting the rear suspension in all directions. I'll talk to my vehicle dynamics professor for more info, he's a suspension guru. |
Technically rear wheel steering should allow higher cornering speeds. The problem with the Mazda system is that it isn't consistant. And when the bushings get worn out it becomes very wierd and unpredictable.
Even a reasonably astute driver will want to get rid of them. Good luck |

[quote name='pengaru' date='Aug 13 2002, 01:17 PM'] ditch the DTSS, it should be called RRWS (random rear wheel steer). It's horrible for bump steer, especially in the rain. And most of us have high mileage FC's and the rubber bushings are tired as hell, making the bump steer much worse. I installed the RB rear steer eliminator bushings (delrin) and the car is completely different as a result, bumps don't make the rear end get loose (this was bad in the rain for me, almost dangerous) and it's far more predictable in turns, definately more consistent. I documented the replacement procedure I used in some digital photos, you can find them here:
http://pengaru.com/~swivel/public_html/pic...ics/09-05-2001/ is there a well documented how-to on stablizing this system? [/quote] er, oops. http://pengaru.com/~swivel/cars/rx-7/09-05-2001/ my bad. these have been posted elsewhere regarding the wheel bearing replacement... since the procedure is pretty much identical. |
Go do some autocrossing, it really gets in the way of how the car feel's on the egde. At first you feel the car is going to over steer and all of a sudden it changes to understeer. so it makes me work harder and i have to turn the wheel more

not even considering how inconsistent it is when turning, it's dangerous regardless.
just going over uneven road surfaces, bumps etc would make the rear end wiggle about, talk about bump steer. if I went over nice bumps in the rain the ass would slide sometimes. installing the rear steer eliminators solved all of this. |
**** i live on a dirt road and the rear moves around a lot just going over rocks at 20mph or less( i dont drive fast down my road the fastest ive went is 25)

When the bushings are bad it doesn the unpredictable dangerous steer on the freeways etc, my friends 7 did that, and wow it was scary. My car does not do that, its predicatble to, only when i hit corners really fast it comes on, and I know what it does, I'm used to it.

that rear steer crap makes the rear end feel "floaty" near and at the limit and i have new bushings..i ******* hate it...feels like positive rear toe (toe out)...bump steer is bad...real bad....i looped it because of a small pothole and i was not that close to the limit
