Guide to Properly Lowering your S197
The stock shocks may "work" -- an people may use them; but if you want to have good ride quality and take full advantage of the improvements in handling that the springs can provide, you need to change shocks. I have ridden in and driven vehicles both ways and the difference a quality aftermarket shock makes on a lowered vehicle is profound. If you step up to the D-Spec, you get the best of both worlds -- the better handling and a ride at least as good as stock. There may be other aftermarket shocks that give similar. Plus, from an install standpoint, replacing the shocks at the same time as the springs is simple. If you do it at different times, you just double up the labor.
Ok guys, I went and did a dumb thing. I test drove a 2008 Cayman. The handling on the thing is fantastic. Now, I've posted my car for sale. But, if I don't get any bites, I need to upgrade the suspension. The set up that c25sailor has looks like it will work well for me also, I'm not sure I need the upper strut mounts and trac brace. I won't be racing at all, I just want it to handle better in curves etc. I already have the Steeda Ultra lite springs(not installed), so this is my list so far. Rear Sway bar, LCA, Adj. panhard bar, shocks and a strut tower brace. Did I miss something? Is there something I NEED? or will this list suffice? Also, this is a great thread.

Good luck either way.
Anybody have a preference or idea on which parts to go with first or in order of importance since I am sure not a lot of people will get everything mentioned here all in one shot. I'm lowering my car next week hopefully so springs are a given. I'm deciding to go with new dampers as well as steeda's upper strut mounts. Is there one or two other parts I should get taking into account its a daily driver... I like to do things right. I was thinking maybe the adjustable panhard bar?? What do you guys recommend as for order of importance?
Sport Springs 1"front 1.25" rear555-8215/16Steeda Adjustable Panhard Bar 555-2551Steeda Heavy Duty Upper Strut Mounts555-8120
Additionaly I can consider but not necessary now:
Steeda Bumpsteer Kit555-8106Adjustable Competition Upper Control Arm Kit555-4106 or 4105
I want to do Roush rear springs only - 3/4 to 1 inch drop. I will get an adj. panhard, but do I need adj. lca's? How much will pinion angle be affected by such a drop, and what are the consequences?
No, you really don't need the adj Lca's 1'' drop or less really wont affect your pinion angle much.
'cause I hate looking it up all the time.

I lowered mine with Eibach Sportline but I only seem to be off by 5-6 mm when i measure from the wheel arch (with a hanging string with a weight) to the wheel centre cap. I was looking at the American Muscle "Swar Bar", wouldn't this stiffen everything up enough without the use of an adjustable Panhard Bar or does one need the Panhard Bar too?

I just did the full level 1 suspension upgrade from BMR. Got it all in red powder-coat. I also got the adjustable rear control arms with the spherical end on one side and the urethane on the other.
With the tokico shocks and struts the car handles awesome with no body roll. I can adjust the dampening of the struts and shocks to firm up or soften the ride. I highly recommend it. as seen below the new upper strut mount made it a snap. I didn't have to disassemble the originals just put the new ones together.


I have already done the drag race phase and with a stock suspension got some great times now I am ready to start carving up the corners in autocross.

1st post lol.
I have done allot of reading at this forum and enjoy it very much.
I recently did the Eibach pro street kit on my 07, very easy to install.
Within 10 minutes on my first test ride the engine is acting up (stalling,jerking). I reinstalled the factory tune then reinstalled Airraid 91 octane tune without mvt. No change. I nearly ran the car out of fuel hoping it was bad gas, i put in new fuel still no change. Tomorrow i will reinstall the mvt and the stock tune and see what happends. I only have 3200 miles on the car, maybe i did have some dirty fuel and the fuel filter is plugged
This does seem a little odd tho, my question to everyone is. Is it possible there are ride hight sensors? possibly intrupting the the engine performance

Morning all I am currently building my suspension set up and want to make sure I get this right. First of all this is almost totally for street use and for appearance purposes. I will be doing a couple runs at a drag track a year but for the most part this is all for street.
I already purchased a set of tokico d-spec shocks as well as the eibach pro kit. I'm also about to buy a BMR control arm relocations and a set of fixed BMR LCA's. My first question is whether or not I have to go with the adjustable UCA. There is a member selling some fixed ones here and I want to know what type of difference I would be looking at if I went with the fixed.
My second and last question is whether or not there is anything else that I NEED to have. Keeping in mind that funds are limited and a SC is coming soon. All input is appreciated. Thanks!
