:confused:I bought the Koni yellow's/spring combo. My car is a 2002 WS6. I will be using it for autocross and weekend drives. I drag race sometimes but Sam already told me that that may suffer a bit. Anyway. 426rwhp, will be using stock 275/40/17 at 30 psi during autocross. The tires are 25.7 inches tall. Heres the kicker... I have 255/40/18 and 295/35/18 on there for looks and most of my daily drive. I will likely get the car aligned with these 25.94 inch tires in the back and 25.28 tires in front.
I need to know what to tell the alignment shop.
Also, I'm not sure how to set these shocks or what to set them on. I'm taking off my tokicos, so I assume the rear adjust similarly. I'm also not sure how they are set up from the factory. I have LCA's and adj. panhard from umi.(well that still hasn't made it).
So please tell me what to set them on and how to set them. Strano is a great guy to talk to when you catch him, However, my work schedule conflicts with his business hours.

Only you'd know what setup works best for you, but I personally set mine to full soft back and 4 from full stiff on front. Note I have 3rd gen rear konis

Mine are set 4 sweeps up from soft on the front and a 1/2 turn up from soft on the rear.
Alignment: camber -1, toe and caster are stock. All info came from Sam. Mine sees no track time so some shock adjustments will probably be needed for your car.

So where are they set when fresh out of the box? Also which perch should I use. I've read there are two postitions. I'm thinking I should use the higher perch given the springs are already much shorter.

What are the stock alignment specs? What should the specs be for a lowered car? Mods in sig.

I need to have mine aligned as well and I want to make sure it's done right the first time.

Not sure if they all come at a specific setting but can't you just check that yourself? Do you have 3rd or 4th gen rears? Aka on or off car adjustable

They don't come set to any particular setting. ^^^Oh yeah, big difference whether they are 3rd or 4th gen rears. I have 4th gen rears. I turned mine all the way soft and then went back up.

I thought that the 4/4 were double adjustable. From the looks of my shocks, I can adjust ther rears by turning the knob at the top only. Also on the fronts. There seems to be a place to put a pin in only. No second knob. My shocks are the one's that are on sale for about $822. Also, what are you guys using for pins on the front shock. It didn't come with one. I'm guessing tiny phillip head.>>>

4/4 just means on-car adjustable (I think?). DA Koni's are much more expensive.

Correct. Also multi-adjustable. The 3rd gens have only four postion adjustablility and must be removed to adjust.

The rears are adjusted with the knob. The fronts use a small allen wrench if I remember correctly

No the 4/4 means it comes with the 4th gen rear which has the adjustment on the top of the shock shaft. They aren't double adjustable. If you are not way out of the stock unsprung rate range, then you don't need double adjustables technically. All you really should need to adjust is the rebound.

I use an allen wrench to adjust the fronts
