TPC Racing DSC (PASM box replacement)

[Phoneix]

Hello folks,

I was wondering if anyone in a Cayman in the UK has tried this module. It replaces the PASM box and is apparently much better at managing damper rates than the standard PASM. Has three modes, soft, medium and sport. Comes very highly recommended on Planet9 and Rennlist but can't find any mention of it on here. In the US it seems to be mainly 911 owners but has glowing reviews from practically everyone that has tried it. I found an article from GT Purely Porsche where it's used in a 997 GTS, again a positive review: http://www.parr-uk.co.uk/media/pdf/performance-rev...

Here is the product:

I emailed them and they advised that Parr are suppliers in the UK. Considering it as it will be a stop gap (and cheaper) than the Damptronics system I was considering, apparently it works well with that system too if I decide to go ahead with it.

I like it when you can tweak it your self and make things stiffer if you wish, ATM you cannot so a no go for me, but self tweaking is coming so they say,

If you own a Cayman I would go with the x73 shocks they really are a nice set up and cheap.

Never got on with PASM and like wise Audi mag ride, they don't seem to work that well IMO the passive set ups on both cars drive better !

Yes, from what I've read you can download some software for the DSC module and adjust it how you like. I have a 987.2 with PASM so not sure I can fit the X73 shocks.

I have it on my 991 GTS and it's fantastic. Only two settings rather than three with their new software - normal and sport, but they are fully customisable (though I just leave it in the sport setup all the time). Car feels way more planted and steering feel is greatly improved. Sport mode is also no longer too firm for everyday use (though the difference between the two settings is less, and I am considering changing 'normal' to a softer, touring-type setup). Basically it just feels like the suspension got way more expensive. If anyone's ridden a bike with regular suspension followed by one with Ohlins, that's the best thing I can compare it to.

On the basis of my experience in the 911 I would recommend DSC for a Cayman too. It's amazing how much performance Porsche seems to have left on the table. That said, if you think about their wanting to release future models with 'better' suspension but without having to go to the expense of changing hardware, it maybe isn't so surprising after all...!

Calling Jack Wood ( the owner of that GTS in above linked article)....

Thanks for that review. More and more convinced that I should go for it. Did you get it through Parr? Fitting yourself? Looks straightforward enough.

I was at a test day with TPC a couple of weeks ago and got to drive their Cayman GT4 with the controller on it. It was absolutely amazing—made Summit Point feel like the surface had been freshly laid and soaked up all the bumps. They also do amazing things when you fit them to a Corvette or Viper. Wouldn't hesitate to recommend one, Mike Levitas and his team really know what they're doing.

Parr look after my 911 and have been recommending this to me. I've done a lot of Google research and have only found good reviews of the TPC software.

I've changed the springs and geo already on the car and I've got my first Euro trip and track days with that set up coming up. I'll check out the current setup fully then consider the TPC box.

The only concern I have is that I want the car to feel quite alive/basic and that is the spring/geo set up I have gone for, if I put a more "live" programme on the dampers will it then feel too smooth/refined?

Parr supplied and fitted mine. Have found it makes the car feel more alive not less, as one can feel better what the road is doing (and there is nothing non-alive about the corner speed the DSC allows..,!)

What is the relationship (effect) between spring rates and the DSC, I ask as I have stiffer springs than stock

[MagicRat]

Above my pay grade I'm afraid! Give Lawrence a call at Parr.

Thanks for all the input. I'm pretty sure I'm gonna go ahead with it but after the recent spending (SD steering wheel and damper)... Maybe in a few months :-)

I'll give some feedback on it hopefully when it's done.
