993 suspension corner weights and alignment
Discussion
going to change my shocks to bilstein b6's with m030 factory lowered springs as the old shocks are past their sell by date.
what alignments would anyone suggest for general fast road with good tyre wear? is the rs setting too much?
corner weights - how critical are these to a road car? i dont drive track days so is this OTT?
any advice much appreciated

Marc. Peter Tognola set up my 993 C2 Coupe on the RS settings when he lowered it and fitted new shocks. Transformed the feel of the car, looks great as well and no sign of any abnormal tyre wear.
Cant help on the second part of your question, but I`m sure someone will be along soon...

I'd say that getting the corner weights correctly set is very important - Porsche give a maximum corner to corner variation for a reason. If they are not about right then the car will handle differently in right and left hand bends, and theoretically it could make for interesting braking reactions from the suspension. In any case, the alignment will have to be done once the new suspension is fitted, and a good alignment service should include the corner weight adjustment.
Wrt the alignment settings, the RS clubsport on M003 has more front end negative camber by 40' per side - that's the most significant difference compared to "normal car settings". Might give dodgy tyre wear pattern on the road , but I'm just guessing
. Ask a pro.
Best of luck.

What are B6's? Are they the stiffer shock but not adjustable like the pss9? What's the cost too?
I'm looking at doing something similar on my TT, along with the settings.
slightly stiffer non adjustable billie replacement for the original porsche/monroe shocks - significantly longer lasting as well
price - RRP £800+ but i know a man who can get them for £590 inc vat
Ehm, how does one adjust corner weights without having adjustable height suspension like PSS9?
Surely you just get what you get or is it a case of the driver being told to lose or gain a few pounds? Perhaps, you have to sit slouched in your seat or drive whilst leaning to one side? This would certainly explain the Chav driving position.

Probably won't be this easy or quick though!

May have gone a little over the top. I guess the question i need to ask is; do 993 RS owners have any problems with the standard ride height / suspension?
That's the ride i'm after.
Since sticking the PSS9 kit on mine I'm at RS ride heights. No problem at all, which is surprising given the steepness of my drive! Firmly sprung on the road, so potholes are not nice, but she doesn't bottom out. I strongly recommend that in tandem with the lowering you stick a front protection bar on the car (Carnewal again) - that way nasty gradient changes and carelessly taken sleeping policemen are prevented from shagging your paintwork.
Cheers

What was the cost of the kit? Where did you get it?
Gert at Carnewal - the PSS9 kit was 1899,70 Euro in September last year, so of the order of £1300 including VAT and postage. I think the front protection bar is around 150 Euros.
When I was fitting the PSS9 kit, Gert had no info to give me on ride heights versus spring plate settings prior to fitting. For info, here is the mail I sent him, just in case you go this way. It will help you set the height before mounting the kit - note that the PSS9 kit gives RS ride heights as a maximum - the adjustment can only take you even lower!
"For future reference, if anyone asks this question again, here is the information from my build. As you know, the spring plates on the PSS9 shock absorbers are set at the bottom of the adjustable range at the factory, i.e. 120 mm front, 195 mm rear. These settings give the lowest possible ride height - measured at the Porsche reference points this corresponds to about 110 mm front, 100 mm rear.
Therefore for someone like myself who want to keep the ride height around that of the RS (I want around 128 mm front, 112 mm rear), they should adjust the spring plates to nearly the top of the adjustment range both front and back before fitting the kit. This will reduce the amount of spring height adjustment that has to be done once the kit has been fitted."

Standard RS settings are nothing too dramatic and absolutely fine for the road. These settings are not so great on track though. I had mine set up by Parr, with a little more -ve camber at the front...a little tow in at the rear and the car sits a slightly lower than standard. I don't think i know any RS owners who actually use factory settings through choice, obviously there are some out there.
No probs with speed bumps and the car handles fine, certainly better on track than before.
