get sway bars before you get coilovers

just installed a set of techart / H&R sway bars, both front and rear and the dynamics of the car has improved noticably the uneasy body roll has been reduced a lot, the turn in MUCH sharper and the understeer are gone when the rear bar is set to the stiffest setting, the car is very neutral if you're on a budget, i recommend just getting the rear sway bar, installation takes less than 10 min and if you have a lift you can do it yourself the front sway bar install requires dropping the subframe and will take longer, proally should get someone else to install Link in the articles section: http://www.planet-9.com/reviews/showproduct.php?product=128&cat=4 and i'm not saying that the Techart / H&R set is the way to go, but that its worked out great without squeaking and they were reletively easy to get, and a good number of sponsors here carry them or at least can order them both eibach and "the racer's group" (TRG) make stuff that will fit the cayman, just make sure you get something that is A LOT STIFFER than the oem bars (front at 25? mm and the rear at 22mm?) GT3 front bars should also work with a slight mod (plz double check on that someone) _ _

Fafnir, It was my understanding that the Cayman already comes with the GT3 bar. Additionally, can you fix up your pole position article there is no article, just pictures, also for the sway bar article it just seems to end, no info about the rear sway bar and review/conclusions so you may want to go back and edit that article as well. Thanks!

I will start by saying I am no expert on the subject. I got the H&R sway bars, front and rear, and I have PASM , the rear is adjusted to the softer of the 2 settings. With this combination I have no desire to add the Bilstein PSS. The ride stiffens a little bit, say 10 to 15% with the sway bars, and with questionable pavement 19 inch tires become a little to much for daily driving. If the roads were relatively good here I would have been happy. As it is, I got a set of 18" wheels and tires and I am very happy with the setup. I would not want to stiffen the ride any more. I am having installed a Quaife hopefully tomorow.:drivingskid: I use my car to drive around and enjoy, and I take maybe 5 or 6 DE's a year. Right now I have more car than driver. My current plans are to continue with de's and "graduate" to R compound tires and more agressive brake pads than stock. Who knows, maybe next year or the one after that, I might want a stiffer suspension, but not now. Just my $0.02 I am happy with my car the way it stands.:banana:

That's not correct, you can upload lots of photos to the Articles section of the gallery, then use the BB CODE link from your uploaded photo and paste it into your article, your article can have unlimited photos in it. I know I know we need to have a step by step for creating articles... Let me know if that gets you going or if not just email me and I'll try to explain in more detail.

OK so same part other than the adjustable ends on the GT3 one, what I mean is that the diameters and strength of the bars are the same, the GT3 has more adjustable suspension components, but the basic rigidity of the bar is the same for either, looks like you could swap em if you wanted to..

fafnir - when you're measuring the torsional stiffness of a hollow shaft (which is what I think you are saying both the CS and GT3 bars are), then the relationship of the stiffness of the two is (DE4-dE4) where D is the outside diameter and d is the inside diameter. (The E4 parts are just where I am attempting to show to the fourth power). Eg. a 30mm OD bar with 3mm wall = 810,000 - 531,441 = 278,559 a 30mm OD bar with 1.5mm wall = 810,000 - 659,750 = 150,250 So with these numbers the bigger bar is about 85% stiffer. Plug in the real numbers and see what you get. Remember the above is only for comparing and doesn't give the real torsional numbers. And the leverage on the adjustable GT3 bar is simple lever math, of course. If there are any younger engineers out there who can remember the math better please have at it!

cayman does not have GT3 bars. if you are on a budget, spring, bars and tires . but to get it really right, coil over, tires are more important. i ran stock bars, but it was dead flat and neutral... back then, i didn' t have much choices on bars, spent most of the time dialing in the motons.

Thanks! I didn't realize it was that cheap...
