Hello All,
I have my name on a waiting list for a build for a GT3 and we will see what happens!

However I did have a question...Would there be any durability issues with rear-wheel steering for multiple monthly track days? I am sure its a great feature however with more moving parts ....and or a catastrophic failure during tracking day driving ei a bouncy turn 17 at Sebring with 4 wheel steering..

What do you all think?

Legit question, but nobody will have an answer until these cars really start getting used at the track. Given that nobody can even drive one right now, it will take some time to get real world feedback.

Good question.

We've posted a bit of documentation earlier this month about the rear wheel steering. link to thread.

Here's how the actuator looks like:



And here's a video of the actuator in action:


The actuator replaces the toe arm. There are 5 links in the suspension, so most of the cornering loads are absorbed by them. However we have no data how much force is being applied onto the actuator (or toe arm) under heavy cornering loads. It's also hard to estimate long term durability just by looking at the part. So I guess the real answer is: we'll just have to wait and see.

As soon as the new motor is in, we'll be conducting more "research"

Very cool vid. Especially nice that you not only showed the close up view of the actuator but also both front and rear wheels simultaneously so that the relative movement between the two could be easily seen. Thanks for posting that!

Thanks for the post Elephant Bart.

Has anyone tracked before the recall?

SamFromTX

Yes, 500 miles on track and 2,000 on road, no issues.

Elephant Bart

No problem. I made the video for our own documentation and for the guys here at rennlist. We were interested in seeing how this thing works. This video also caught some interest from magazines and blogs. AutoWeek and flatsixes posted an article based on this video, and it became somewhat popular on youtube.

Great video.
If I see what a beating the 997 GT3 parts take at a track like Sebring, it's hard to image that this will keep functioning without being Enduro race tested..

Which racing series allows rws?

rijowysock

i would assume just as resilient as front wheel steering...

I wouldnt worry with new car warranty and CPO thereafter...

I always wanted to post that but I kept forgetting. Thanks!!! Someone will say the front have mechanical input as well; true but the rears move a little only so there is much less "electrical" force being applied per degree (minute) of steer.
