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.

January 2022 Update: All of our ZZP W-Body coilovers now come with the 04+ style front lower mount. 04+ Grand Prix do not need to change to the 97-03 style control arm any longer.

Install note: Per our video below, we recommend 2 spanner wrenches width of preload on the front springs. 


Fitment note: What we've seen is there are some variations in bodies across the w-body platform, whether it be yearly changes or casting differences. With this you may have to clearance one of the top mounting holes for the front coilovers to fit all three studs on the top hat cleanly. Before installing check the clearance of the studs and make sure they don't have stress from the body putting pressure on the stud.

Way better than kyb drop ins

I put over 2500 miles on them for break in. Height adjustment is wonderful, you can adjust two wheels in 25 minutes with an impact gun and a jack. Maxed damper settings are laughably hard and should only be used for the track. The lowest setting feels so bouncy it feels kind of unpredictable around corners at highway speeds. I’d go between 10-20 clicks for the sweet spot for these. In that range my gtp almost handles as well as my stock 91 MR2.

Pretty dang good

Overall expiring every was good. I had a lot more struggles getting the old guys off than putting the new ones on. Dropped the car about 2 in all around, and fine tuned the compression/rebound and the car handles well. They are a lot “Harder” feeling than stock, but I’m going for a sport build so it works for me. Would recommend.

Easy and Worth It

I installed these in my driveway very easily with the help of some basic power/ air tools! My goals were to stop tire rubbing, lower it, and improve handling. I did some measurements and got great results first try! I was able to align everything with the trusty string method until I can take it to a professional. My '16 Impala Limited handles a lot better and no more scraping. Still looks like I could go lower. Great product. definitely recommend it for anyone trying to achieve any of the results I sought.

Coilover upgrade

Love these coilovers! Got my old struts out and these fit right in. Way better feel and I can soften them up for long trips and firm them when I want cornering. Hard to beat
