just wanted to know if i can get a strut tower brace to fit my 2000 bonne and also does anybody know the size difference with the sway bars from the FE2 suspension , FE3 and the FE5.

I just saw about a month ago where a member installed a GP GXP suspension in there Bonneville.
They said it'* on rails now, it'* so stiff. The sway bar is thicker and solid in the GXP Grand Prix'*

So it can be done.

it bolts right in with no mods?

I'm not sure. I'll try to find where I saw that.
Is your suspension shot?

hi, i installed the Bonneville GXP suspension (FE5) onto my SSEI that had FE2 from the factory

here is the post.

the swaybars are larger, and they are solid, the struts have different valving that are stiffer, and the springs are a thicker diameter

also not shown in that post is the GXP Struttower bar

also if you dont have an SSEi, i have the FE2 suspension and Brakes off my SSEi that im looking to part with

see, I knew someone here did this.

Thanks for chiming in

i have a 2000 SLE but i think it already has the FE2 suspension and the brakes are the 11.9 inchers.

not all the SLE'* have the FE2. I would check your RPO codes in the trunk

thats where i found it at

How about just installing the GXP sway bars and struts and keep the V-6 springs?
I am leaning toward the sway bars myself, but would like to see if Bilstein makes a suitable strut for our cars. I am a big fan of going with a softer spring set, but stiffening up the shocks/struts and bigger sway bars. You gain on the handling of the car, but retain the suspension compliance over road irregularities.
Has anyone else done this yet?
