i know the 2nd gen rx-7's have some kinda rear steer thing and i was just wondering if it has any benefits. im sure mazda must have thought it was good for somethnig i was just wondering what if anythnig it does. ive seen a bunch of stuff about how to lock it up and keep it from working so i was wondering. i was also wondering if the 90 gtu came with a lsd.

well the 90 gtu did not come with the lsd. i think the rear steer is supposed to be easier to drive/ more forgiving?

my 89 GTU didn't have lsd but if i dropped the clutch @ 8000 rpm i would leave two 25 ft strips. DTSS is supposed to make it easier to drive for inexperience people...

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:

keep the DTSS! if you know how to drive with it the car can get thru turn so much better!

DTSS and AAS were both marketing crap mumbo jumbo in my opinion.



no DTSS or AAS is working in these cars anymore, and I'm not aware of any way to purcahse new DTSS bushings alone. Last time I checked the mazda dealer only had one part number for the entire toe control hub assembly, and it was very expensive.

Its probably bullshit, just like the variable toe geometry in the fd's. Makes them too tailhappy comming out of turns.

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.

this link was no good, it took me to a picture of a penguin in a coffee mug and some controller picture.



is there a well documented how-to on stablizing this system?

yah i agree. i wish you could have just gotten a base car without any of the bs
