I have units in stock ready to ship! We leave for Sebring tomorrow to do testing for the week at the David Murry Track Days event and then the PCA club race. Once we get back, we will be back to shipping!

If anyone is at Sebring for the PCA event, be sure to stop by and say hello. Our DSC Sport engineers will be on site as we are testing our 997 GT3 Cup car with Tractive DDA shocks controlled by DSC!

 

anyone with the DSC in the south florida area? I would love to test it before buying.

Sounds like a great product. Have been hearing a lot of good about this recently.

 

Has anybody finaly made some track tests also?
Before and after, some skillful driver behind the whell.
If it works then 0.5-1sec faster time would be great to have.

 

Is that the OEM turbo wing in your avatar? Also don't forget to post a review of the DSC here.

 

I have it on my 2008 GT2 and must say it is awesome!

 

Order placed. Harris was very easy to deal with. Looking forward to some fun this weekend.

 

I just make my payment too, can't wait to test it & give my review.

 

Just to add balance not all good reviews. This fellow had a shocking experience.

I tried 4 DSM units on my Bilstein Damptronic GT2, first unit was rock hard all time, second unit triggered PASM warning light third and forth just didn't seem to work right, the ride was always harder than stock and I couldn't detect any better handling than standard.

All units went back and I have lost confidence in the product mainly because it is so hard to quantify an "improvement" over the factory unit and I guess I am thinking how much development time went into the GT2 settings by the Motorsport dept of Porsche/Bilstein and how equipped in terms of resources are TPC to do better.

^ interesting review by TB993tt. This is totally contrary to my experience with the DSC module. I have no reason to doubt his experience but "stiffer all the time" run counter to what most have experienced (including Randy Pobst). Could there have been something unique to his built car's suspension? Maybe Harris from TPC can chime in, afterall I have to imagine they must have been in contact with him if he exchanged the DSC module three times!! Thank for sharing IMI A

To quote TB993t (the guy that was sent 4 units)

"Personally I would like to see some sort of comparative data of a eg 997 turbo lapping a circuit with and without DSC. I'd like to see position on the track speed lateral acceleration longitudinal acceleration which dampers are being stiffened and the speed of the stiffening and by what degree and finally that the lap time is faster with the DSC."

I completely agree. For the money thats being asked i.e. $1,190.00 not unreasonable to see some comparable data. Perhaps TPC can arrange for an independent test to be carried out as if it works will sell even more units. Quality issue are of concern to me though. I'd be very annoyed in that guys shoes installing and uninstalling units 4 times even if it is just a 15 min job.

 

Thanks for posting the link to Tom@TPC's reply. Seems TB993t had a unique string of bad luck so I totally understand where he is coming from. However his experience appears to be a rare exception. TPC's customer service in that situation was exemplary!

Interestingly, this is a test that can be conducted fairly easily given how easy the switch is. Three laps with OEM unit, (either pick the best lap time or average out the three laps) then switch and repeat! Although I already have my answer, (I found that I could take certain corners +5 to +10mph faster which would mostly likely result in improved lap times over stock), this might be a fun test to conduct...

 

I understand what you mean but you know even if it is was 1-2mph quicker through a corner thats a massive difference. It will never be 5-10mph quicker. Thats the difference between a small hatch back and a McLaren lol.

I'm also not sure that being quicker is the purpose of the module but I'm sure TPC can tell us. In the soft mode on OEM car I find it too soft for certain roads especially for fast road work here in the UK where roads are terrible. This is exaggerated even more as my 997 turbo basically has GT2 RS engine set up so everything can lose composure even more quickly on a technical piece of road. On track I found the OEM sport setting absolutely fine but on road its far too hard for our roads here in the UK. A set up with an in-between setting is what I think TPC are maybe trying to give us and on road yes that set up will be ultimately faster because the cars mass is therefor (in theory) more controlled. On track on ultimate hard settings I actually doubt there's anything in it between OEM and TPC module all things being equal but happy to be proved wrong i.e a track test as you're outlining.


The quality control issues are more of a concern. To be honest none of you guys really know if the module is even working properly.

 

I agree, being quicker isn't the purpose of the DSC module however, I believe the improved damping effects allows the tires to maintain more contact with the road surface which in turn allows more control in a turn/corner (extending the range of traction that the car can sustain before giving away, or spinning out)...that increased level of traction/grip make all the difference in how aggressively I would dive into a corner which should positively affect my lap speeds. Further the reduction in body roll afforded by the DSC module should also aid the lateral weight transfer that occurs in corners, this stiffness should also improve cornering speeds, all of which should improve lap times. The module may not be designed to make us go quicker but its positive benefits should do just that.

On whether the module is working properly, well we can feel the improved damping effects (compliant behavior), the improved stiffness, the absence of CEL (that TB993t experienced) and the modulation of the modes (i.e., subtle differences between modes 1-3, unlike TB993t's "always stiff" perception). All these lead me to believe my module is functioning as intended but like you said, we could be wrong...

Honestly I think TB993t had a unique one-off unfortunate experience...numerous reviews both on here and Rennlist support that.
