Where I can find a lowering spring kit for my 94 bonneville SSei..... Grand Prix - Gen 2 SSC lowering springs, on zzperformance.com, will fit on my bonneville ???

No, Grand Prix springs will not work. Lowering springs for your car will be custom. Do a search on 'lowering springs'. You'll find a couple members that have done it.

They custom make to ur specs. Was quoted about $300 for mine. U have a choice on heavyduty.......front drop/back drop. Haven't got them cause there'* alot more to do to drop our cars the right way!

That'* correct. I think 95naSta (Mike) is still getting things right after his drop. Trying to adjust other stuff to get his geometry back.

Some places sell a KIT to get it right, but there is nothing like that for H bodies.

Yep. I got 2" front and 1.5" rear F41 spec drop springs from www.coilsprings.com. The rear 1.5" drop ended up being closer to the 2" front.
With my the drop I needed 1* camber bolts for the rear. The front however had plenty of adjustment left.
Right now I'm trying to figure out how long my endlinks should be to bring the preload of the strut bar back to factory specs.

i dont know if this helps --

Drivewire

ok so i can't seem to get the link thingy to work but whatever -- you can copy and paste

dont know if it will work or not or if it'* not what ur looking for but there you go anyway

Hmm. thats a new on to me. But only a 1" drop?

I wondered the same thing but then thought that maybe 1" would not affect the other parts of the suspension as much as your 2" drop did. But that'* probably just wishful thinking I suppose.
