only the rear springs are a progressive rate coil....

no idea on the price but there are 4-5 different stiffness rates for FE2.....so you could get a FE2 that was close to a FE1 or one that is close to F41...keep this in mind

you want to grab 4 springs from the same car....swaybars are the same for ALL FE2 and F41.....

suspensions are a tricky subjuect when you get into the different combos that were offered on the H and C bodies

Hmm
Any good suggestions where to find a set? Did GM even quote spring rates for any of them?

Junk yard is your best bet. Save money and they're still good. You can get them from any H or C body with FE2 or F41. As for different variations in stiffness for the SPRINGS, pat would have to chime in to know what cars have what stiffness.

Junkyards are the best bet for the springs...the only way to know is the tag that is listed on the spring....the only problem with this is that the little tag is usually gone, and then there is NO way to know the EXACT spring stiffness

OK guys... I'm going to jump in here and say we are going to be careful with what we reccomend...

He has a C body, this is an incredibly close relaitive to the H body( Streched may be the right word )...

I have done a lot of research on the 92-99 Springs where the FE1 and FE2 - F41 come in....

I believe that he can go to better front and rear springs either made by Moog, TRW .... But I'd have to research that more... And I think it would be considerabilly less than $200 for the springs all the way around and give an all around better ride... But what I need to figgure out is what the stiffest spring was for the car and then see if that spring will cross to the Bonneville or vice versa...

On my 95 SE the rear spring has a 860lb load rating... The stiffest spring I can find( Tanks to Arron for proving it ) is a 1250lb rated spring.. <---- This spring will actuall have a 1/2" lower install heigth... But the ride quality and handling of these springs on arons car was exactly what I was looking for.. Not harsh, but a nice firm ride that let you know the car was attached to the road....

So we may have to do a lot more digging into this issue...

But if you are going to replace the front struts and you have the $$$, get the strut mount and bearings... Mine are failing on my 95 and I have to go back into it again.. At that time new springs will be installed

bigerik if there is anything I can help you with, please let me know

thanks Don....i was wating for you to jump in this topic

BigEric the Moog/TRW springs are available at Advance, we recently learned this from a Advance employee that has them on the rear of his Bonneville....they are almost like the F41 coil thickness...and the ride was pretty good

but you will WANT to get the FE2 bars when you do the stiffer springs

Thanks to you both!
That is damn encouraging! I used to work for Advance and still have some friends there. Anyone have a clue about the part number or what it is supposed to fit?
This is an awesome site.
Looking forward to having the worlds best handling 98....
Erik

Would you by chance have a Micrometer so that you could Mic the front and rear sway bar for us... as your car is a little heavier I am wondering what sway bars it has for stock... for the front you should have either a 30mm or a 32mm, and for the rear either an 18mm or 21mm...

I'll have to research the springs a bit and see what comes up... This is a 95 Olds 98 ...

No mic on hand right here, but I will see what I can arrange.
Yup, it is a 95 Olds 98 Series II, meaning fully loaded, except for the fact that they special ordered cloth (?????) as leather was standard, and it has the analog dash, which should not have been available on it. Go figure!

Bigerik...

After some research I have some info for you bud... The C body does use the same springs as the H body... That would go to figure as the C body is a streched H body for the most part..

Its odd but it may make sense, the Front of your car should have the SSEi Bonneville springs with a 519LB load rating( Bonneville SE was 441Lbs )

If you want to replace the springs you'll need Moog or TRW CC658

For the rear I am actually a little confused as to why they would use such a soft spring on a car thats larger than an SE Bonneville.... The Spring listed for your car regaurdless of NA or SC'd is the CC 661 830 Lb load rating...

The rear springs on the SSEi are CC653 and have a 1230 Lb load rating...

It almost looks like getting the air ride to function again and adding the CC653 springs may make you happy as I am sure the back end has a lot of float...

This is what I have found from the research.... But if you know the right guys at Advanced, I'm sure you could get a bit more in depth in your quest for springs... Wink

If there is anything else I can help with bud just let me know...
