I called up Ground Control and talked to Donovan, apparently this kit won't fit Bilstein struts and they are not planning on offering this kit for Bilsteins so I'm going to have to look at other options. :/
Glad to help out; will do tomorrow.Orrr buy the ground control kit, take it down to a machine shop and see if they can machine on the part that is the problem. Scott, can you post a few closeup pics of the red anodized threaded cup that slips onto the strut housing (shown in pic below on the right). Would really help me out!
Sweet, if I end up getting the PSS9 kit and I need those rear perches I'll get ahold of you, I'd take the springs too. Thanks Clem!I wonder if those Bilstein rear adjusters are 2.5" already cuz it looks like they are designed to fit on the lower control arm. If that's the case, I have a set of 2.5" upper perches from Maximum Motorsports I could send you and 6" 500 lb 2.5" springs too that I can't use. You would be set!
The Ground Control kit offers the ability for adjustable height and also the ability to use and swap out different 2.5" springs. The goal with the Ground Control kit for me was to make a set of Bilstein coil-overs and save a lot of money in the process. Since I already have a set of Bilstein sport Struts/Shocks those cost me nothing. The Ground Control kit + Corksport camber plates would end of running me around $800-900. So for roughly $800 I could potentially have a set of Bilstein coil-overs.So what is your end goal exactly? Adjustability of height? Damping?
If the latter, find a local shop and start with what they support.
I understand your passion for KW and I'm glad you love your V1's. I'm equally passionate about Bilsteins so I'll be on Bilsteins one way or another. Thanks for the lead to Philrab, I would be interested in selling my current Bilsteins and will contact him when that day arrives.Idea
Philrab on here is looking at billies to replace his stock shocks, why don't you sell them to him for a great price and stop putting in so much time and effort into making something you have work, and just pick something that already works? like a KW V2 or V3 that takes at least a standard front spring and an adjustable rear perch of awesome design and never look back.
Re-valving isn't cheap and is a repeatable cost that just adds to your total in the long run. KW's engineers are fantastic and I LOVE my V1s (only height adjustable) as they sit.
Heck, start with the ST Suspension kit (KW V1s with 5 year warranty and not stainless shock bodies) since it's under a grand for all 4 corners and see where you want to go from there.
I hear ya, some suspension guru's (Dennis Grant included) have knocked the Bilstein cheesewedge system saying it's not that good. He also knocks KW's too and says they aren't that good either. So when it comes to coil-overs that are considered excellent by the guru's, there are none available for the Mazda3 that I'm aware of unfortunately.Except if you go with the PSS9, the "cheesewedge" adjuster is apparently the worst in the industry. If that's the case you'd be better served with custom-valved standard Bilstein struts.
Re-valving is a one-time cost for most people because we know, empirically, what baseline curve works. And almost nobody below $2k gets that curve right out of the box, aka almost everyone below $2k needs a revalve. The KW v3's on a friend's Gen2 are slick, but the high-speed compression damping is too high. Large, fast bumps are actually harsher than my BC setup despite his rates (6k/4k vs 8k/6k), and he loses speed vs. my setup on any 60+mph corner. His KW's need to be revalved more digressive if he wants to optimize his car for larger racetracks. I have a hard time imagining the v1's would fare much better.
