To all rotor-heads...

Do all 3rd gen RX-7s (1993-up) still have that awesome feature where the back wheels turn in the opposite way the front wheels do (like the 2nd gens) so that going around corners is suuuper fun, and you get the incredible cornering power too???

Thnx, spy. :alien2:

Um...no rx7's do that. I wish they did though

Ummm YEAH THEY DO!!! GEEZ!!!!!!!!!

Um.....dude, I am positvely absolutely sure my cars rear wheels do not turn or any other 7 at that.

Yeah, what are you talking about? I've never heard of that on an RX-7, or any Mazda.

I doubt any rx-7's have that. I could be mistaken but have never read about it, heard about it, or seen one with it.

i don't know about 3rd gens but 2nd gens sure as hell do. it senses a slide somehow and adjusts the camber of the rear wheels to couteract. check out any good rx7 site and you can buy rear steer eleminators so that you can drift better

Do you have a FC? I don't know where the hell you guys come up with this stuff. Can you supply me with documents stating that this is in fact true? I have owned 2 gtu's and a turboII and I they were not equipped with this mecanism, none of my friends FC's do either.

DTSS = Dynamic Tracking Suspension System. Basically, it means that Mazda put loose bushings in the rear end so that the rear wheels could "steer" a little bit when the car experienced side loads, kinda like a cheap 4-wheel steering. It's easier to look at a picture than for me to explain it. If you give send me a PM with an email address, I can send you some pages that I scanned from the 88 brochure.

So it's passive, and just depends on which way the weight of the car pushes the wheels?

:confused:

I wouldn't mind seeing that: [email protected] Heck, shrink it a bit, and just posts it here. :D

I am also interested in this, I had no idea Mazda had anything like this. if you get the chance Send Them Here ([email protected])


Thanks.

I'm not surprised at all. That's not technically four wheel steering, since camber is different than the wheels turning, however, I have heard of this technique being used before in vehicles. 1988 or so Volkswagen Jettas even had something similar to that. It's quite simple technology, so I wouldn't doubt a techie car like the RX-7 having it.

I guess I gotta find my own pics. :p Sorry, freeway if you've sent them already... ;)

It had an independent, Dynamic Tracking Suspension System with trailing arms, triaxial floating hubs, camber control links, coil springs, and a 12 mm anti-roll bar (14mm with the sports suspension). The company claims to have applied for more than 100 patents on their Dynamic Tracking Suspension System independent rear suspension. With DTSS, the rear wheels become an active component of the steering system, changing from toe-out during low lateral force cornering to toe-in for extra stability during high lateral acceleration cornering situations and to reduce oversteer which had been a problem on the 1st generation.

thats awesome, i never heard of that before. so was that only on the 2g's?

From what I remember yes, only the FC's had that...

Personally I don't like it.. especially since I'm and un-experienced driver the car feels really loose out back... and well I don't like that... need those damn rear-steer eliminators from Racing Beat. :)

I think that's Nissan you're thinking about.. and it's called HICAS. It was on the 300ZX I think. Basically the rear steered a VERY little bit in the opposite direction. Real drivers hated it, because it would make the car do something they totally weren't expecting when handling at the limit. Matter of fact, they sell something called a HICAS eliminator now, to get rid of it.

Yes the FC's did come with it, but as someone said real racers hate that feature, I believe the 2nd gen Preludes had AWS as well, You could get either ABS brakes or the AWS but you could not get both..who knowns why..Anyhow the FD3S which is the latest body style of the RX-7 here in the U.S. pulled a .99gs in the Skidpad in the R1 trim, the Touring editions were not too far behind..

The part to prevent the rear steering effect is called the Rear suspension upright Toe Eliminator. I just sold a set to a customer of mine for his club race car.

I cant help but read this thread and think to myself "do these guy really own these cars and not know how they work?" i have an 88 base now turbo, 88gtu fresh rebuild by me, 86gxl parts car, and a 88 vert all equipped with the rear steer set up. by the way its not fun and im in the procces of eliminating it cause all i do is drift. it is as simple as welding the rear control arm solid and welding in a few carefully placed braces. "for us who like to drift on a budget" ' or you can spend the 250 at mazdatrix and get the full eliminator kit. now im not claimin to be a genius on 7s but if you have any questions please feel free to ask i might be able to help you.:runaround: check him out hes driftin.
