Group Buy: ADDCO F/R Sway Bar Kit

The front and rear addco bars I got from I believe Summit Racing about 2 years ago had everything with it.

Are you glad you did the upgrade? My girlfriend wants to know what I want for Christmas, and I'm leaning toward the Addco sway bar kit and UMI brackets.

IMO the Addco bars made a huge difference in handling and cornering.  Alot less body roll.

I went back through my orders and these are the ones I got from Summit.  I just called Summit to double check on the rear sway bar becuase I couldn't remember specifically.  It does come with everything needed.  I did not have to get anything else for these to install.

Jordan: the Addco bars and UMI bushings are a great next step in your mod progression. Your engine should be making a decent amount of power right now. IMO, upgrading your suspension and brakes will make your car both safer and more fun to drive. The bars dont just make the car better at cornering, they make the car feel more modern. If Buick released a Riviera next year, it would have more power, but also would likely come with larger wheels, lower profile tires, and a tighter suspension. Why wait? For a less than a single car payment, you can drive a "new" Riv this year!

Aaron, I think you're right. I feel like I'm not getting the most out of my sticky tires with the stock suspension in place. There is still quite a bit of body roll that needs to be reduced. I also have factory struts on the car. Would you recommend replacing them as well? I know that's a a regular wear item but I haven't replaced mine because they seem to still be fine.

If they're the original struts,they're toast.jmo.

Robo's right. I'd replace the struts first.

Jordan, your comments made me think: unless you know you'll be okay with the car having a very firm ride, you may want to take the suspension upgrades one step at a time. Replace struts first, then maybe HD links, Addco bars, and UMI bushings in that order. If you do everything at once, expect the car's handling to noticeably change.

I keep forgetting that not everyone wants a harsh ride. I wouldn't call mine harsh yet, but it's headed in that direction. Whenever I ride in a stock Riv, it feels really soft in comparison. Maybe just updating your struts to something like KYB GR-2 would give you a level of firmness you're comfortable with.

I would do struts, sway bar links, strut tower brace bar, then a fatty sway bar.

That's the order I did my front suspension minus the springs. I experienced noticeable improvement after EACH upgrade.
