      Only one problem.

      If you order these with the rear top mounts, like I did, be wary of it. I have absolutely zero complaints about the coilovers themselves, they're excellent! The ride quality, the build quality, and the overall feel and appeal these have are 10/10. However, the getting shafted out of $55 and having to purchase mounts from a local parts store was not part of the $1050 bill. The coilovers arrived 14 days ago and the mounts that I called and emailed about 3 times within 2 days of getting the coilovers, showed up out of the blue today. And still no word on returning the mounts for my wasted money yet. But all in all, these are a fantastic upgrade for the price. Why spend nearly the same amount of money on 4 way adjustable shocks and lowering springs when you can spend less in total and get actual coilovers? Listen to the description and get the 8k springs up front, or go the extra mile and get swift springs. Either way, you'll be glad you nabbed these!

      The Best Suspension Option Available for the W-Body. 2002 Grand Prix GT

      I bought these coilovers a few months ago and I was very impressed. The kit comes with 2 front coilovers, 2 rear coilovers, longer sway bar end-links for the rear, as well as instructions. You will need to purchase two new rear OEM strut mounts. I did have a couple of issues though. First, I would recommend loosening all of the springs and resetting all of them to the recommended 4mm of preload. I had some rattling coming from the front which I found was due to one of the front springs rattling around from too little preload. Second, DO NOT get the recommended spring rate of 5k for the front. BC Racing North America messed up somewhere along the line because the 5k front spring rate is way too soft for the front of these cars and I promise you will not like your ride quality at all. I contacted Jon here at The Midwest Parts Group and he sent me out a set of 8k front springs without me really having to ask him to. Let me tell you it is a night and day difference. The 8k front springs and 6K rear springs are what should have originally come with this kit. With the new spring rates the car rides exactly as I was expecting when I first purchased the coilovers. It is noticeably stiffer than stock without being harsh. I have these coilovers, the GMPP front and rear sway bars, GMPP front and rear STBs, and some poly bushings and I can out-handle my friend's SN95 Cobra of which he has put thousands of dollars in the suspension and I have a FWD car! Just to provide some evidence that the 5k springs are too soft, I have included some pictures of the 5k springs as well as the 8k springs when the car is sitting in my driveway. The 5k springs are black and the 8k springs are gold. As you can see, the 5k springs are almost experiencing coil bind with the car just sitting on level ground and the 8k springs have plenty of room for suspension travel. Basically, I'd just like to say that I am very happy with my purchase but only after I installed the 8k/6k setup.

      What the W body needed!

      This is by far the best suspension upgrade for the W body! I’ve tried multiple combos and nothing compares to these. Well worth the money in the long run. Would highly recommend!

      2005 Grand Prix

      Installed these coilovers with the zzp front and rear strut bars and my car feels like it's on rails now. Definitely a night and day difference.

      2000 Pontiac Grand Prix Coilovers

      These are absolutely amazing. First BC coils I've ever owned and the only ones I'll own in the future. These are the best coilovers in my opinion for the reasonable price. Not going to break the bank, but you get a great product. Only compliant I have so far is that the front coils don't go as low as I was hoping. I could remove the bottom lock ring for the spring, and then get another 1/2" lower. But with the bottom shock mount being tough to spin after tightening the bottom two bolts. I don't know if this is an issue with my coils specifically, or all sets, but it's a pain to adjust height because of how difficult it is to spin the shock. Other than that, I have no other issues. Would be nice not use the stock rear top hats, but that's just a minor inconvenience. Thanks again BC Racing! I will come back for any other cars in own in the future!

      Also: Fronts are completely maxed. Can't go any lower. But the rears can still go much much lower
