I haven't even sat down and read everything about it but if you hook at the track not sure how it will help you. Someone that is hit or miss then it may have to be looked into further.

My thoughts also. I am cutting 1.50 -1.53 60' with a full weight cat on stock power with stock 2.62 gears. I don't think any more can be gained without adding power or losing weight. Now if I went to some of the other tracks around me this may help.

Paladin, have you seen anything quantitative that you can post on the street? Times, greater speeds in a given area, etc?

Great write ups folks.

Let me help. It is tough for anyone to believe opinions or subjective stuff. What I have been saying is the difference is rather subtle. I had our marketing people do this yesterday. Sorry, he did not at least put a sound track on it. He did such a good and fast job, I did not want to go back for re-work.

Anyway, bottom- best lap last year, this car.

Top, best lap this year this car, the DS unit was the difference.

I keep talking about and they keep talking about stability and it’s ability to keep the ride reasonably soft and forgiving unless challenged. Most of the lap shows rather similar data in the corners. However, the most dangerous and most technically challenging is the potentially high speeds and potential of gaining time in what is called the Kink and IMO the semi straight track that follows, encased by walls on each side. Just prior to that is the legendary chicane. The differences for me begin in the Chicane, through the Kink and beyond. It is a bit of a driver preference on corner entry speeds, yes. But you need the confidence in your car to push it a bit. It’s all good but at about 1:35 the difference I am talking about becomes apparent. Plus on the lap last year, I see I let it rip into the Kink, only to hit the brakes and be timid after that v. this year where the speed is more smooth followed by INCREASING speeds OUT of the Kink. The result was getting down to Canada corner much quicker. That segment displays what I have been trying to say with regard to this item.

Mine just came today. Installing it tomorrow to try out on the street.

Looks like I won't be able to make it to the track till next month...

Seeing a bit of odd behavior with mine, and wondering if anyone else has seen this.

Default Mode in my car is set to 700+, Street, Street. If I bring up my SRT pages and select Track (700+, Track, Track), I get a yellow triangle and exclamation point beside both the power setting as well as the suspension setting, and a message saying that these settings cannot be changed as this time. (even though I'm not 'changing' the power setting).

But if I go from Default to Sport....THEN to Track, all is good.

More of an annoyance than an issue, but just curious if anyone else has seen this...

I have seen steering stick for a few seconds going to track. I saw that before the controller also. Sometimes I have seen other stuff, but again, saw it before it also.

Thanks. Tried just leaving it there to see if it would eventually switch over, but after 5 minutes or so, still nothing.

First time seeing anything like this for me, and it started happening as soon as I installed this.

Maybe I'll look for a fuse to pull for a bit, or disconnect the battery for 10 minutes or so to see if that takes care of it. If not, no big deal. Like I said, more of an annoyance than anything. And the improvement (at least on the street) is well worth it. I'll see how it behaves at the track in a few weeks.

Minutes, huh? It don’t take that long when mine sticks. You may want to call DS and see if others are seeing the same. Not seen this on both Forums yet. How do you like it otherwise?

If pulling fuse 48 doesn't help, that is going to be my next step. Again...more of an annoyance, but it can be resolved, then I'd like it to be...

So far I love it. I've only had a chance to drive on the street so far, but it certainly makes a huge difference. Certainly a much smoother ride. Also (and this is kind of tough to describe), but my car felt like it wasn't really 'connected' to the road. Almost a feeling like the tires were over inflated. Putting this on took care of that. Feels much more connected and confidence inspiring. If that same improvement in feel transfers over to the track, I'm going to be a happy camper.

Reading your write-up in regards to the chicane and the kink, my track has something that sounds like it gives me same feeling (albeit at a much lower speed). Downhill slightly off-camber left hander leading into another off camber right at the crest of a small hill, followed by a slightly banked on-camber (thank you!) left. You really need to have confidence and commit to that first turn, otherwise, you either lose a ton of time, or are all screwed up for the next few turns. Hopefully this will be the ticket.

Having each shock working independent of each other should certainly help with nose dive under braking...not to mention overall cornering. Corner exit seems like it might be a bit less squirrelly as well.

All in all...looking forward to my track day...

You are correct on all accounts. I can really feel the 4w independent control also. It really is a great cruiser. We did 500 highway miles this weekend and it was great.

Also on the courses, use the whole road, they smooth out the rumble strips remarkably well.
