Upgraded suspension for a buick?
 

Is there a better racing/performance suspension upgrade for a buick?
is there another car that has the same?
I would like to put 15's or 16's and maybe lower it 1in or 2
and make my handling better.
Also what kinda brakes/calipers can i also get?
All this stuff will need replaced in the next few months so im looking at all my options.

It's a remote possibility, but you might be able to take the suspension from a SSEi Bonneville and put it on. But, like I said, its a remote chance it will change over.

Check out Brake Rotors Brake Discs Drilled Slotted Rotors and see what they have for brakes and calipers. Ive always been happy with stuff I ordered from there.

on the 92-94 you can swap the front knuckles form a 96-99 and be able too put coilovers and big brake kits on but idk if your 91 is the same
