stiffer rear shocks

Like a piece of solid round tubing for no compression... haha

No, spring helpers... only $10 and WAY less effort to install at the strip.

It's pretty easy to adapt shocks from a different model. Find something that's close in length, then work with the mounting. The shaft will either be 10mm or 12mm. As Jon said, Beretta mounts are 10mm. It's easy enough to drill the sleeve a little larger (I've done it), if the new shocks are 12mm... very few companies make 12mm shafts, but Bilstein is one of them. Just take it slow drilling so the sleeve doesn't rotate and separate from the rubber. For the bottom, you may need a different size sleeve there as well. Cut out the old one, which will be surrounded in rubber. Many suspension bushings can be cut to fit after you find one with the right size metal sleeve. Control arm bushings are a good place to look... the parts guy will hate you, but chances are you'll find something. Cut it down so that the rubber is a little larger than the hole, then use a vice, clamp, or press to push it in. Another option is to get a metal sleeve then use window weld to fill the gap. I did something similar to this for a set of shocks.

konis are worth every penny. I just had to drill out the top shock mount like everyone is saying, bottom bolts up. set on full soft they are at least 2x stiffer than kybs. full stiff and you would be lucky if you can get the car to move jumping on the bumper.

I believe modified is correct about what saab shocks to use. I can never rember. I can dig up my reciept if you want to be sure

it adjusts compression and rebound equally

Koni's can be adjusted very stiff.

yeah stiff isnt always the best performance. Mine arnt even adjusted half way up..

I was told differently...

Maybe its time to get a set this winter... I do have a bad set of KYB's that I could cut up for the front struts and do all 4 corners at once.

Alxsmt Please find that receipt if you can. Get part numbers and I'll PIN them in here.

I found PN# 8040-1057 SPORT for Saab 9000 95-98 for the rear adjustables. Please verify this for me.

One other question I have is what is the extended length? I know I put the wrong shocks on my 95 once, they were for a 94 and they were too long compared to the 95, so when you put the car on a lift or jacked it up by the body the axle would drop far enough for the springs to fall out. I just want to make sure that these would be the proper length for 95+ as well as the 94 and older rear axle, and not end up being too long.

Ok, this is why PN's need to be verified...

Koni says this about their shocks.

Yellow Shock Absorber
External Adjustable Rebound Damping

this is on the 8041-1191 shock that J-body guys have used...

Saab 9000 shocks are 8040-1057 and those do not have the same quote.

Ill try and dig up my reciept tomorrow. the length isnt too long for mine, not a clue about the newer setup. not even sure what it looks like lol. Struts are fine too, It seems like you can use inserts for an eclipse that are longer. just dont use KYB strut mounts, I was told mine (new) were bad when I was getting an alignment after the swap.. they are noisy..

I swear I read or was told it adjusted compression and rebound equally. Ill try and see what I can find to confirm that. just emailed koni. I know turning the knob changes the stiffness when you jump on the car (maybe I have compression and rebound mixed up?)

Single adjustable Konis adjust rebound only. It's in a tech article on the website.

Thanks guys. Guess i will look for koni's then. The car seems to be pretty nervous on the rear(bodyroll), especially at higher speeds (60mph+), i noticed this on mountain roads too and i dont like that. Still have to install the rear swaybar though but the rear isnt that stiff as i thought it will be.

A big rear swaybar makes a huge difference with these cars.
