ZZP W-Body Coilovers

Here at ZZPerformance we continue to push the limits of even our oldest platforms, we continue to develop and produce new parts well past the last car rolls off the line, which is why we're so excited to bring our new ZZP W-Body coilovers to market. 
With the knowledge gained working on previous projects we decided to create our own line of ZZPerformance coilovers. Through extensive testing we have found an optimal spring rate, 6.6kg front and 6.6kg rear. Perfect for the daily driver or those looking to track their w-body car. This spring weight has been highly debated within the community for years; however, after testing various spring rate setups, a heavier spring (like the 8k) made for an uncomfortable ride and created handling imbalances. Competitors Coilovers include a 5kg front spring in their kit, ours being a touch heavier benefits performance while not hindering ride quality. Ride height adjustability is done via the shock body, meaning spring pre-load is preset for optimal performance. We went with a long front spring and shock combo to retain suspension travel, something that many coilovers lack. These coils adjust anywhere from stock height all the way down to be able to tuck tire, meaning you can dial in your ride height for any desired stance.

As many of you are very familiar with the current BC product offering you will get all those features and then some with our ZZPerformance coilovers. ZZP coilovers weigh less, and include a custom top plate instead of reusing the stock plates. We moved the sway bar attachment to the body of the strut to better control load. We offer double the warranty of BC's, 2 years against any defect. This shows how much we stand behind our product. Our coilovers also come with more dampening adjustment range so you can fine tune for your specific build and desired ride quality. Our coils were built with every climate in mind; being based in Michigan we know how much the elements affect suspension parts, so we made sure the welds are up to our standards as well as the powder coated lower collars are reinforced to withstand rust. All other components are anodized, or powder coated to resist rust, we do this because we know nothing is more frustrating than your coilovers getting seized after one winter of daily driving. No one knows W-bodies more than us, and we know that these coilovers showcase that.

Zzp w body coilovers

These are really nice as always with zzp. Less money than the BC racing ones. Less weight and custom top plate. More dampening range. I almost bought the BC racing ones but I am glad I waited and these came available. Just waiting for zzp to restock on headers and poly engine mount and I can try these out

Great product

The studs on the front coilovers were a bit of a struggle to get through the holes at the top- 2 would line up easily, but the third would not without "convincing it". I've had them on for a couple of weeks now and have zero complaints on the ride. Still need to adjust mine up a little bit more as the vehicle's pretty low with them at the setting they're on now. Ultimately, the real test will be how long they last.

Excellent new suspension upgrade option!

Just installed ZZP coilovers on my turbo 2004 Regal GS "Bad Grandpa," along with boxed trailing arms and strut tower braces. Install was as easy as a normal strut swap, after setting ride heights and following ZZP's YouTube tips on rebound settings. Started with just 1" drop compared to stock, and it looks and handles much better than extra soft Buick struts. They seem a little more responsive than my GXP with the best OEM setup offered on W-body's, and I'll even try cranking them up at the drag strip later on, although I'm enjoying the Virginia mountain roads as-installed.

The best!

Recently installed these on my 01 MC SS Ride is beautiful! I did a 2-2 1/2 inch drop all around . I also added the motor and trans spacers. I love every bit of these deff get an alignment after but 100% buy em!

Beyond all expectations

I recently got these installed, and have been dialing them in for a few days now. These coilovers absolutely rock, the car feels planted and 10 years newer. Installation was a breeze, no cutting or modifications of any sort. Would highly recommend an alignment afterwards, as mine is ruined. If you're looking for excellent suspension,I cannot recommend these enough.
