Spacers,Firebird Rear-Jounce-Bumper

[blackTA6585]

I bought c6 18" rims 10.5 wide and I've been seeing websites that say you need the rear-jounce-bumper for any camaro firebird when installing 17" wheels. What would I need for 18" wheels? My car was stock with 16s. Could I use the one for 17" wheels or do I even need them at all? Also what exactly does it do? Will I see a difference in ride height?

no need for them... useless waste of $ to get them.
On top of that SS/WS6 bumpstops are worse than the Z28/Firebird version of them.
Keep what you have and don't worry about it.

Cool thanks for the reply. I put my rims on and they fit fine so far. Havent driven it yet.
