I only have good things to say about West End Alignment in Gardena, CA.
Darin has corner-balanced and aligned my 993 a few times over the years.
I am very very picky about the way my car behaves, and he has nailed it every time I've asked for something different. My alignment is now fully customized.
He is an expert on all 993s.
Everything is done by hand, no laser!
I would just call him... He is very passionate about his work, and He will answer any questions you might have about the ever so worshiped KT tool!

I have a dumb question. If you buy the pss10s do you also have to buy springs? If you do, what springs should you get? How much are they?

OverBoosted28

Pss10 is a coil over system, so no need for springs.

TheOtherEric

Since you drive mostly on the street, you do NOT want to be at RS ride height because the bump steer pretty much ruins any enjoyment. It's really that bad. If you don't want to drop $2k for RS front spindles, then just stick with Euro ride height or thereabouts. BTDT.

Coil over is car slang for coil spring over shock absorber. You still need a spring. So do they come with the coil spring, or not? If they do, what spring rate do most folks use?

address the maintenance items before the mods

Some things can be done in stages others not
PSS10 is a stand alone mod

tie rods are not, if you want RS tie rods you need to use RS wheel carriers
For a mostly street car i'd leave the stock wheel carriers and tie rods and somewhere above RS ride height, if you want to go to RS or lower ride height for better handling then get the RS wheel carriers and tie rods.

sway bars are a stand alone mod

bushes are a stand alone mod, but depending on the condition of the oe's that may come into the maintenance realm, Again for street use i'd do all the bushes/arms at once and align the car once. I'd also include the PSS shocks as part of this stage.

Bill Verburg

If you have ever driven a car w/ KT out of whack you would worship the tools too, w/o them there is no way to tell if it's right or not, maybe it's just good enough to not be too objectionable, only the tool can determine that.

Bill Verburg

W/ PSS you do not get to chose, Bilstein developed them as a complete system, that comes w/ shocks and springs and perches. It is set up to use stock shock mounts too.

PSS 9 came w/ 225-250lb/in fr 400-685lb/in rr

I assume PSS10 use the same springs

JB 911

Bill, why the range in the spring rates on the Pss, how does that work? Is it because each coilover has 2 springs? As opposed to M030 033 etc which just have one?

Bill,
Thanks for the advice on stages. I'll start with the shocks, arms and bushes.
Is there anyone in SoCal that can get KT done? Was told Darin doesn't do that.

Spent Saturday at the Streets of Willow as my start point for the car. Noticed a lot of body roll and sliding of the rear. Also on the tighter turns, a lot of front end push. Especially coming off skidpad onto front straight. Now this was on the 17 inch cup 2s with the street continentals that came on the car and I hadn't been to the track in 2 years. Took a while to relearn the lines. Fronts tires and wheels seem too narrow. Oddly, the ride wasn't as rough as on my canyon and freeway roads.

Cupcar

Jae Lee at Mirage International does a compulsive job of kinematic, wheel weighting, removing rear stab bar pre-loading and alignment. He removes the rear coil overs, puts in a dummy shock and sets up dial indicators to set the kinematic as he move suspension through range of motion.

Jae also builds engines for Singer Porsche cars, so he knows his stuff.

Highly recommended.

How important are the sway bars in the 1st stage w/ the PSS10's?
Since I'm not going to RS carriers & RH, do I need/want the adjustable RS bars initially or can I run Turbos/similar?

Bill Verburg

Sway choice is a relatively minor tweek tool

here are the most common 993 choices, in mm, the better choices for performance are in green

TRG sway bars 25/22mm 5/3 adjustable

RS bars 23/20mm 5/3 adjustable

stock 993 sways 21/18mm
993 S sways 20/20mm

MO30 22/20mm
tt 22/21mm
M030/tt combo 22/21

4S 20/20mm

GT2 22/21 5/3 adjustable

OverBoosted28

To add to Bills list on Sway bars, are H&R 26/24mm 2/2 F/R

Since we are Talkin Maintenance on a 20 ? year old Suspension I Just wish to add that I had an Interesting Adventure a few days ago after a DE.

My Left Wheel Bearing is Very Loose - Broken? Needs Replacement 4 sure!
Who knows what else - ???
When off the ground my left wheel Moves Freely

My Right Rear Strut is Leeking Fluids. Bilstein B6 Hd with 40,000 Miles on them.

My Right Rear Wishbone (In Part Manual) aka ? Toe Link Rubber is a little Twisted.

I have Not done the Research But....No idea which failed First But started Hearing a Gringing over last few days.

Not quite sure how all of these items were damaged But Perhaps we should ADD Bearings to all these Bushings?

Last year I changed all M030 Rubber Bushings on the M030 sways on Frame as well as Drop Links Front and rear (Stabilizers per US Online Parts Manual)
I suppose that accelerated the wear on The Rear Toe Links / Control Arm?

Now I could use some recomendations on a Repair here But also feel this info should be shared

Perhaps I should have started a Fresh Post - noit tryin to hijack - felt this is Relevant.
