So I want my 968 stiffer. Especially in the rear. My car is a non M030.



I have Koni adjustable dampers and Techart lowering springs on the front. But I feel like the rear and even the front is a little saggy. Might just be my rear dampers set to the softest settings.

So far my plans are to get polymer bushings. But I'd probably need better sway bars and maybe a strut brace?



Anyways, the real question is, what kind of sway bars would be my best bet? I'm not gonna make it a race car but I just want it less saggy.

let's start by figuring out what the front spring rate is. that will determine the rear rate needed.



konis on the front. which ones? where are they set right now? (counter-clockwise to stiffen)



what shocks are on the rear? koni yellows? (clockwise to stiffen)



M030 swaybars are decent for most applications. be aware though that porsche changed vendors, and the front bar is no longer the same spec as previous. lindsey racing makes a nice set of matched bars. i've used them a couple of times now, and am impressed.



bracing will tighten things up, especially at the lower caster points.



the single biggest improvement you can make in the car is to get a good 4 wheel alignment, complete with ride height set. if you have adjustable height struts, add a corner balance to really nail down the car. there is a thread here with a few sets of specs (alignment specs for your car)

They're yellow konis both front and rear.The front is set to the stiffest setting and seems like that works alright. But the rear feels a bit saggy, not much but some.

I have to take the rear dampers out to adjust them, right? Doesn't seem like the biggest job in the world but I would prefer doing it with the car on a lift.



The car got a 4-wheel alignment in January. But I plan on decreasing the negative camber at the front a little bit and then getting everything aligned again.

full stiff on a koni yellow strut would require a 300# spring or better. if you have the same techart springs i had when i bought the car (uber rare by the way) they are progressive 150/250, and lower the front about 1.25". that setting should be about 3/4 stiff.



in the rear, yes, you have to remove them to adjust them. then you have to reach inside the top and remove the foam piece, compress the shock fully, and rotate the body. it will only give you a few settings. for stock torsions with no helpers the setting would be either full soft, or 1/2 turn from full soft.



ride height is the key to getting these cars to behave well. if the car is raked one way or the other, even just 1/2", it upsets the weight balance quite a bit

I'll go change the stiffness to 3/4th. Might be the cause of my problems right there.

could be. you could be "jacking" on the front, creating essentially a pivot point, leaving only the rear to move.

That actually sounds like what I'm feeling from the car. But if this fixes my issue. Would polyurethane bushings and M030 front and rear bars improve my cars handling?

not really on the bushings. besides, they tend to squeak, and require regular cleaning and greasing to work properly. unless you are after every last bit (i.e. a track car) better off staying with rubber. i went with spherical monoballs on the blue car, because i was setting it up for track. now, i wish i had stayed rubber. on the white car i am staying rubber.



the M030 bars will help a lot though. the lindsey kit comes with new bushings.

I just came back from a test drive after softening up my front dampers. Flash, I'm extremely impressed right now this helped a lot.

Better everything to be honest, even the acceleration felt a bit more crisp.





So new rubber bushings with M030 bars it is.

glad to have been able to help.



you would be surprised at how many people crank those things up too far.

I expected the car to be a little smoother when softening the front. But not like this, it was really significant.



And another question; strut braces, do they really do anything on a street car when running my setup?(including the M030 bars)

don't take my word for it. do some reading here. there are a bunch of reviews of my strut tower brace and lower suspension brace.

I'll do some research on them. They're usually pretty cheap and easy to install.
