just ordered mine from tom today... looking forward to experiencing the magic...

F1CrazyDriver

hopefully he still has it !


i have the following
-dog bones
-toe links
- rear drop links
- semi solid engine mounts
- exhaust

that is it for "none oem" mods.


that said, the tpc unit makes the car much more bearable on the street...much more. almost does not feel like a gt3 boasting around about its imperfections.

yup- those are the key area's of improvement w the box.

I have monoballs and there are essentially no rubber pieces anywhere in my suspension. The DSC really does make bumpy roads more bearable. It allows the suspension to move up and down over bumps rather than the entire car bouncing up and down.

A Big Thank You to everyone using DSC and for your valuable feedbacks!

I'd like to take this opportunity to address a question that often comes up. Which is, does DSC improve laptime? The definitive answer is DSC improves vehicle stability, which doesn't automatically improve laptime if the driver drives at the same pace as before. With the improved stability the driver now has the option to drive the car quicker using the increased available tire grip as a results of vastly improved shock damping management on the existing shocks- True Fully Active Chassis Management. Even if the driver chooses not to drive any quicker the increased vehicle stability results in a greater margin of safety. BIG Kudos to the DSC users taking advantage of the increased vehicle stability to produce better laptimes!

IMO, for the cost of less than a set of premium brand tires to achieve full potential from the existing shocks, DSC is a dynamite deal. Last words regarding laptimes- I've been in the motorsports industry for a long time, perspective speaking, even the high end $10K+ shock suppliers don't guarantee laptime, the proposed improvement is usually certain characteristic(s)/reaction(s) that the driver/engineer are looking for. One more Big Kudo for the DSC users pushing the edge of the envelop in the spirit of our competitive nature!

F1CrazyDriver

Agree. Proper wording would be- gives confidence to push the bar a bit higher due to extra stability.

Switchbacks is were i saw the most benefit and long sweepers. Car gives more confidence to stay on throttle or go faster.

Another vote here.

I've posted on it before; my 997.1 is just completely transformed.

as many have pointed out, the best way to describe the car with DSC is that it simply inspires far more confidence than before.

where you would back off because the car started to feel skittish over broken tarmac, or would pogo on undulating surfaces, you can simply keep your foot in it.

i HAVE noticed i now seem to trigger ice mode on my ABS much more frequently now. to be honest however, i think this may be because i'm simply driving much faster than before, as i used to back off the gas a lot earlier.

anyone else experience this?

make no mistake though: the DSC is an absolute MUST for any 997.1 owner IMO.

Thank you for your feedback.


There is a youtube video by Derrick of PFC. A portion of this video specifically addresses Ice Mode(or ABS limp mode). According to the data PFC collected and interpreted, this phenomenon is trigged by exceeding a g-load threshold during the "stab" of the pedal. Naturally, the faster the mph + maintaining around the same braking distance = higher g. Basically the conclusion of the video is short of buying an expensive motorsport ABS system the only other ways to prevent Ice Mode is to decrease the "stab" rate or use brake pads with less initial bite. Hope this gives you an idea of why/how.

Ok sweet. I was kind of hoping the TPC DSC would help enough to let me keep them. Car is just so responsive with the monoballs. But on the street, after 30 min of driving, I have suicidal thoughts....

^ I've got Champion Motorsport monoballs on my car, they're not that bad dude...

Plus the car would benefit from the combination of the two on the track.

A more gradual application of the brakes can reduce the occurrence of Ice Mode, and this technique may be even more important when using the DSC box.

There is no free lunch; in most instances there are trade-offs and an improvement in one area may lead to an unintended adverse consequence in another. The DSC dynamically and rapidly increases the front dampening under braking to prevent nose dive and keep the splitter from scraping the track into a turn (e.g., Turn 7 at Watkins Glen), but is it possible that this same rapid increase in front dampening rate could also increase the occurrence of Ice Mode?

It will be interesting to see what others experience on track, especially in those bumpy braking zones prone to inducing Ice Mode. Are any of you using the DSC box on track notice any increase in the occurrence of Ice Mode? Thank you.

Tom@TPC Racing

Anything is possible, but I think the contrary based on the physics of the dynamic damper function alone(without factoring in extreme g spikes to exceed street car ABS threshold from driver stab rate and initial bite rate of brake pad compound), in that the inertia moment from brake dive is actually reduced. With the stiffer front shock damping the ABS Might engage sooner but in such case ice mode shouldn't occur once ABS is kicking in.

There have been a number of DSC users with positive results from Sebring and other tracks, including the Co-Chief Instructor of our region(Mr. D). Really no one has expressed to us at all that its a "I want my freaking money back" type of situation regarding increased occurrence of ice mode. I am a DSC user, I have not experienced ice mod myself, could be that I am brake pedal squeezer, not a stabber. We would love to hear from DSC users regarding ice mode as well.

Tom@TPC Racing

Sorry for getting off topic. I came across this thread regarding ice mode, I find the info in post #17 to be very accurate and applies to our cars-

Tom - Thank you for posting your reply. Like you, I am a brake squeezer, so I have never experienced ice mode - knock on wood!

Certainly not bashing the product, which seems to receive positive reviews, but I am interested in the possible affect of the DSC damping function on the occurrence of ice mode. Not sure how common it is, but Hesperus' post was the first user feedback I've read on the subject.

I remain interested in experienced track user feedback. In particular, instances where the occurrence of getting into ice mode has increased, or where ice mode was routinely experienced with the stock controller but the frequency of occurrence was noticeably reduced after installing the DSC.

Would love to hear some apples to apples lap time comparisons with and without.
