TPC's DSC box and new Active suspention
#31
Im sure someone else will have this question...
Confirmed with TPC that the box is the same for both the 997.1 and 997.2 turbo models. Includes S and GT2. The cardboard box might have a .1 or .2 sticker but it doesnt matter.
There are also yellow and white dsc boxes. The yellow was just and earlier hardware run and their supplier switched to white. They are the same. That being said if you have a yellow box it might have older software. Hopefully the user upgrade software comes out soon and everyone will get on the same stuff. But yellow or white all still work on turbos.

I think the front spring mounting pad sounds interesting too.

My DSC box is held in by plastic clamps on the bottom of back of the firewall footwell. Do I have to unclip the box or unscrew it out? Two of the plastic pins won't unscrew so I have to pull the covering back to reach under there. It's a pain to get under there, just curious so I don't break anything. thx

It just slides into the clips, nothing to unscrew, just an awkward position.
These are the directions Tom sent me
Chris,
Easy installation. 5-steps. See below.
1. Remove key from ignition switch. Then make your way to the passenger side.
2. Locate the stock PASM module. It is located above and slightly forward of the carpeted trim panel nearest to the passenger right foot. There's no need to remove the trim panel. Just reach your hand above the trim panel then slight forward and you'll feel the flat surface of the PASM module.
3. Once you have your fingers on the flat surface of the PASM module, follow downward and you'll feel the plastic locking tab.
4. Gently push down on the locking tab and the PASM module will fall out of the retaining bracket.
5. Carefully unplug the electrical connector from the PASM module and transfer the connector to the DSC module. To install the DSC module onto the retaining bracket simply line up the upper tab and the bottom will snap into the locking tab.

I wanted to clarify that I like stock bell-shaped Sport(M030, I030 option code) springs for use on mostly street driven cars with stock type struts/shocks for its superiority over bumps, mild lowering of ~20mm, and less sag than the non-factory bell-shaped springs that I've come across.
A note on sag(aka settlement), its a common thing, usually not a big deal especially if its on threaded body coilover that can restored the original/desired ride height. I dislike having to change the suspension geometry more than I feel its necessary in order to do get wheel alignment to specs when there's no adjustment to restore height. If the car is never to be on a track then its no big deal. I only steer customers to use stock Sport springs only if they are looking for mild lowering on stock type struts/shocks because that's what I'd use in such application. I don't even sell stock springs.
For flat out track performance, the "straight" springs are the way to go. With our DSC/Tractive DDA program, we are getting straight springs to have street compliance near that of bell-shaped springs.
Here's the photo of the springs. Bell-shaped spring on the left. Straight spring on the right.

Tom, do you recommend Eibach/GMG sways for the 997.2 Turbo S in addition to any type of other changes whether it's B16+DSC, GTS-4 sport springs+DSC, Eibach springs+DSC, B8+DSC, or just DSC by itself? Sways may reduce body roll but does it give me better traction and contact patch on this car?
Second, on B16's+DSC with your "narrow minded" focus on performance even if it's 90% street 10% track, what spring rates do you like? By default it's about 350 front/550 rear and I've seen some go for 450 front 600 rear. The goal is always max traction/contact patch first, with second priority being the feeling of precision, less body roll, etc. We need weight transfer obviously to load the tires for traction during cornering or braking, so at roughly which spring rate is that balance of grip vs feel?
Assume running Cup 2 tires.

Can someone confirm where the PASM box is on a RHD car? Is it in the same position relative to the glovebox (i.e on the left side - passenger footwell - ) or does it remain in the same absolute position as in LHD cars (so in a RHD car it would be above the fusebox)

Same position relative to the glovebox. Open the passenger door, stick your head into the passenger footwell and it will be on the upper left, just above the edge of the carpet. You can reach up there and feel it relatively easily. Just a case of releasing the clip on the bottom edge, and removing the cable.

Anybody ever track down GTS sport spring part numbers?
