I'm definitely going to lower the car. When and with what I'm not sure yet. The GRBS kit can be made with a custom spring rate. Their kit is 30% stiffer than stock. That's more than I'd like. They are able to provide a custom spring rate as well. So now I have to do some figuring. I'm...

I took my car to the dealer on Saturday and, although they say they did nothing, my car went up the hoist and down and now it's fixed. Either I'm crazy, or some wiring harness got stretched I don't know. But the skipping out is gone. The rear and the front are in sync now, and no more...

Yes. I have a quote from Kim at Type-4 in Korea of $1655 USD plus freight of about $300.

No wise man never changes his mind upsidedown. You're right re the bracket on the shock body. I'm now in correspondence with the manufacturer and was sent new photos. I'm still waiting on the answers to a bunch of questions. They are mono-tube shocks, but that means the reservoir must be at...

I sent in a request to Type 4 Shock absorbers. They are in Korea. I'll advise as soon as I get something back. Fingers crossed. Also taking my car to the dealer on Saturday. I'm going to compare to another Stinger and see if I have a problem. Fingers crossed for that too.

What I see is a wiring connection on the shock body just below the GRB decal. One is on the left side of the body and one on the right side of the other body. The canister 'wire' is actually a hydraulic tube that threads into the shock body to allow for rod displacement to flow to what's...

Are the shocks/struts manually adjustable?

Now I'm going to blow my cover and reveal that I'm a suspension geek and a past shock absorber OEM application Product Manager. Unfortunately that can diminish my credibility because I can be labeled a fanatic/flake by the dealer and ignored if I have a problem that is very hard to describe and...

Does anybody know how to reach the company? I've searched the internet for GRBS Suspension/shocks/springs etc and can't find a website for the company.

Can anybody comment on how it affects the performance of the car in handling and ride?

Guys, the Stinger suspension sucks. It hurts to say that. But I speak truth to power. In sport mode I just did some spirited driving and with a g bump in a sweeping corner the car lost all its composure. Corkscrewing with the rear outside bottoming out badly with the inside front popped up...

Hey SeoulStinger, let me know how things go at the track. I haven't had a chance to really assess the suspension as it should be. I think you'll be impressed with the lateral controls like roll pitch and dive. Very impressive in those modes. I am still interested in the vertical control...

@trekker. Thanks for the heads up on the summer tires. I've got to do something. Like move to California!

Interesting news re suspension: Quote from a magazine: "To paraphrase him, the spring rates, roll-bars, and damper hardware are ripe to ratchet up to Audi RS or BMW M levels. While he also suggests Biermann could employ a MDM-style angel mode for its ESP system if he wanted. Biermann will want...

Let's be thankful Motor Trend did not award the Stinger with Car of the Year. They lack cred and in my opinion the award goes to their major ad revenue generator. Besides, a niche car is best kept a secret. I have a beef with the softness of the suspension. But there is no porpoising or...
