odd dtss idea

i was looking at the DTSS bushing placement today on my rear hubs, and was wondering why couldnt u just stick a metal shim in between the hub and the control arm to stop the rear from steering hence not having to take the hole damn thing apart?

I thought about making my own POM/Delrin bushings, it should be easy
FYI Delrin-(DuPont)is POM or Polyoxymethylene

Why what? Why kill the DTSS? because when you're on the edge between having the rear end and losing the rear end, unxepected changes in rear grip do interesting things... It's a good system until you exceed its capabilities, and then it gets in your way.

Only if you don't have sufficent experience with it.

Once you understand when and where it kicks in, you will be able to take your car past limits that a non-DTSS equipped FC can go.

I think our own Ted (ReTed), proved that the DTSS equipped car will consistently high speed out corner a DTSS removed FC.

More info Please, a link to ReTed's data could help. I though that the DTSS just gets in the way of "on the limit cornering".

After reading some other posts by ReTed, it seems to go like this...

DTSS = Better overall handling, with a limit on how far you can go, hard to predict w/o experience.

Rear-toe Eliminators = More predictable, extends the limits of how 'far you can feel comfortable going', however, the speed you can take turns is lower in comparison to a functional DTSS .

I dont know about that. I dont know how you can get used to the feeling of DTSS equipped car. Its not a linear feeling really, its effects differ depending on the situation.

I believe this is why the DTSS elim. bushings feel more "predicatable" because you dont have to worry about the DTSS going nuts.

Also, when the rear is loose without the DTSS, it was much easier for me to catch.

A quote from this site.
The live axle of the first generation, one of the RX-7's inheritances from the RX-3, was abandoned in favor of fully independent rear suspension, using semi-trailing arms with DTSS (Dynamic Tracking Suspension System) featured a " Tri-axial Floating Hub " and an extra link to overcome the oversteer-inducilng toe-out during cornering, which was typical of simple semi-trailing arm suspension, and control the camber changes inherent in that suspension system. With DTSS, natural toe-out predominated below 0.4 g cornering force. This, in fact, helped in steering the car around turns. During harder cornering, however, the suspension load, the geometry of the links, and the calibrated bushing compliance combined to counteract the toe-out and generated net toe-in Toe-in was also created during braking, which aided stability. It was, in effect, passive 4WS. Though generally praised, DTSS was not without critics. Indy car engineer lan Reed, writing for AutoWeek, called it "an attempt to correct a basic design flaw"; ie., the semi-trailing arm setup itself.
I would love to read some more of what people thought of it at the time, if I could only find it. Yahoo is letting me down.

the whole premise behind my idea is just shoving a piece of metal between the hub and the DTSS part of the suspension arm basically making DTSS not work, and not having to do the 20 million hour installation of pressing in all new bushings

BattleSwing (alex from BattleVersion) said "DTSS eliminator bushings?! Its easier to shove a piece of metal in there and get rid of the DTSS for ever."

This guy knows his stuff about suspension since he's a top drifter around these parts. If you have some cash and a press available, get the RB ones. Either way will work fine.

Actually, my claims were that the DTSS does an admirable job, if you can work with it.&nbsp The system was designed for normal drivers who can't control a wildly oversteering car driving through abrupt transitions under heavy cornering loads.

Eliminating the DTSS is a viable option for those looking for performance driving.&nbsp The mod would definitely stablize the rear end and allow better communication on what's happening in the rear.&nbsp When you first do this mod, the car's rear end feels slow to react, but it's a lot more controlable at the limit.

Alex of Battle Version would've give a damn if it had DTSS or not - he's still drift it. *grin*

HEHE so will the 360 master Ho. Hey Ted I got 360s down and that shi$)#(&( is fun. hehe. Hey I drove an 88 NA at the event and it has the RB bushing but it did not feel bad, still has that spin out easy tendency but really not that bad. Looking to sell the FD ( which you will like. ) and get a Q45 and go VIP. ( which will make you jump back and say " what the master is going pimp style! ) What you think of Q 45?

It would shatter or bend. There is not enough absorption with metal as the bushing.

really? i know for the s chassis cars they have rear subframe solid aluminum bushings available.... maybe the rear subframe bushings dont have a different load forces then the dtss bushings...

I made my own bushings out of Delrin/POM.
They have taken all the abuse ive given them the last 6 months or so.

Dont ask I dont have any more of them
