The ROW -20mm sport suspension option package DOES include a mechanical LSD. My point is that the suspension parts are not 'integrated' with the LSD, in that they provide a handling benefit (and ride quality trade-off) on their own, without the LSD. The LSD's benefits apply to all suspension set-ups.

 

how does the lowered springs effect the performance and feel with the system on? Also I have heard that changing springs on other cars will decrease the life expectancy of the factory shocks, any known problems?

 

PASM Normal - slightly stiffer than stock. Not too harsh.
PASM Sport - about the same as stock

As for the life expectancy, I suspect I'll be replacing the shocks due to age before mileage.

 

Personally, I wouldn't change the springs without changing the shocks.

 

PASM set up? I would think a coil over system would be best but what is designed to work in place of the factory system?

 

I don't have PASM (and neither does the original poster, from what it appears). One reason I didn't get an S is because I prefer a conventional suspension.

 

With or Without or somewhere in between. Personally I like the the PASM, it is great to turn it on for the "spirited" drives, however the city streets sometimes are not nice for the sport mode (especially with the wife in the car).

 

I haven't driven a car with PASM. I prefer consistency from every aspect of the car, which is why I don't like electronic intervention.

I imagine the conventional set-up is somewhere in between PASM modes. It can be harsh on a bad road, but it's still completely tolerable as a daily driver.

 

I guess that the PSM must drive you nuts.

Thanks for the input.

 

Not really...it's not intrusive. Very hard to get the 997 out of shape when driven with sanity on public roads, and I turn it off on the track.

Drove me insane in my E46 M3, though.

 

Below is a post I made previously on th ePSS9's I fitted to my C2 a few weeks ago........

So I had the PSS9 coilovers and Fabspeed mufflers fitted to my C2 today by Performance Automotive of Malvern PA. I haven't had a chance to give the car a full workout yet as it was dark and pouring with rain when I picked it up, but initial impressions are very good.

The PSS9's seem to be amazing. First off, the car looks great lowered an inch or so (I'll post picks this weekend), but more incedible is the ride/handling. Both the ride and handling have improved considerably (vs the old base suspension)..........I thought it was supposed to be a tradeoff between one or the other! The car feels much more hunkered down and hugs the road better. The steering feels weightier but still very precise and communicative. The ride feels "heavier" and smothers the bumps better. Part of this is probably the excellent set up job by Performance Automotive (who are known locally for setting up Porsche track/race cars). I was a bit worried at first that the ride would be too hard, but the suspension is set at 5F 5R and feels great.

The Fabspeed exhaust is also great. beacuse of the rain I wasn't able to open the windows and really hear it, but I really like the new rumble at idle and when I hit the throttle. I'll have to test it out more full tomorrow. I know that many people have the Fabspeed so no new info on that count. I also fitted the 'S' quad tips........not because I'm pretending to be a 'S' but because I really like the way they look (better then all other tips I've seen including PSE), and I also wanted something to look different after fitting a "sports exhaust". They seem to stick out a bit further than the factory fitted 'S' tips, but look great. With the lowering and the new tips, my car now looks (to quote Pete from Performance Automotive) like a BMF (Bad Motherf%$^#r)

All in all a very good investment. It's always a bit worrying when installing mods that you might not like some aspect of the car as much as before the mod, but in these two cases I have no regrets!

 

Nigel,

Now that you have some miles on the PSS9's, do you still believe the ride to be more pliant than the stock C2?

 

Like many of the above, I like the lowered look. Monday I'm taking the car into Ruf to have it lowered with their lowering springs (sourced for H&R?), alignment, etc. Nice to have them just around the corner
Glad to see from the above that ride comfort doesn't seem to suffer too much

 

Yes - I was just thinking today how great the ride feels. Sure - you can intimately feel the surface of the road beneath you but it never feels harsh or bumpy. I took my car for a fast drive on some windy, hilly roads today...also pretty bumpy in parts, and was amazed at how composed the car is a speed. You can feel the relief of the road but it never felt unsettled or got thrown off course a speed.

 

I don't know if it is "integrated," but it is included in Europe. You can only get the ROW M030 option with an LSD. Here it is directly quoted from Porsche UK:

"Suspension lowered by 20 mm front and rear; stiffened springs, dampers and anti-roll bars; includes mechanically locking rear differential (multi-plate limited-slip differential)"

The only thing you can't get is PASM and the Sports Suspension. The PASM dampers are incompatible with the ride height and spring rates in the ROW M030. Since PASM is standard on the S, the ROW M030 is a no-cost option that deletes PASM on the S in Europe.
