SPOON rigid collars install

I live in the rust belt. Wouldn't these cause galvanic crorosion, and in use weld the subframe to the body. Otherwise I'm in for a set.

That's actually an interesting question. The answer I suspect is "maybe." Assuming these are aluminum (too lazy to confirm), all there would need to be is some kind of material between the Al and the steel (ie paint). Worst case scenario, bare Al against bare steel, it would probably take a decent amount of time to start corroding to a noticeable amount.

I wouldn't be too worried about galvanic corrosion between aluminum and carbon steel, especially if the contact surfaces are painted. I might be concerned if it were between aluminum and stainless steel, but it is not. To be extra precautious, you could always apply a liberal amount of grease between the two surfaces, that would at least help.

Lastly, the aluminum would be the part to corrode, so you wouldn't be in danger of destroying your car, just the $$$ sunk into the rigid collars.

TL;DR probably a non-issue

Are these pretty easy to install?

I just started a chat on their website, included the link to this list of these interested group buyers, (I count 12 including me). I'll see if they have the authority to start a group buy. i'll get back to you if they offer a discount.

[KoolBRZ]

They're asking about $500 for both front and rear sets. A 10% discount from buying separately. I asked if we could get a group buy price of about $350 instead? They'll get back to me in a few minutes, I hope...

[KoolBRZ]

Anthony @ Rigid Collar will give us a code for 20% off. If both front and rear sets are ordered at the same time, you save an additional 10%. That's a combined savings of 30%. That would bring the combined price to just about what I asked for, $360, instead of $350. Close enough. That's the price before taxes and shipping, Your totals will be different depending on what your taxes and shipping will be.

Via Spoon: "Rigid Collars are made from a secret blend of space materials which ensures they mount perfectly flat between the chassis and subframe taking up any imperfection in the mounting surfaces."

So we can assume the Collars are an alloy blend of sorts. When people say "space materials" they usually mean Titanium Alloys (in my past experiences) which tend to be unreactive. Are you concerned about an Electrolysis type reaction between the metals?

I agree it is probably not an issue.

The discount code is "SPC_ASLMT15U" and the website to order from is "http://www.rigidcollar.com/manufacturers.html". I'm ordering right now before the boss finds out. There is no guarantee how long this code will last. Act now or be disappointed later.

[KoolBRZ]

Just bought them. I encourage the rest of you who are interested in a group buy to order soon. There's no guarantee how long this code will remain in effect. Although the purchase wasn't as smooth as say, Amazon or Ebay, it was logical and secure. I wasn't Verified by Visa on my preferred card, so I used Paypal instead. There was some lag time processing the requests, but be patient, you don't want to order multiple times. It does not conclude with the CC info, but instead verifies shipping info before completing. Don't be suckered into closing before it's done. Verify your shipping, complete your purchase, and make sure to print out your receipt. You might need to refer to that order number later.

thanks for setting that up!! I will buy when I get home tonight.

Probably no one will know but just throwing it out there. I'm interested to know how much this, over time, might wear the contact points when installed between the body and subframe.

Since the engineers didnt design the car with these collars in mind.

[KoolBRZ]

Actually this will help prevent wear to the contact points. The contact points are part of the problem. The contact points are neither completely flat nor completely square to each other. The other part is the bolt holes themselves. They are much larger then the bolt diameter, allowing easier assembly at the factory, but room for movement on impacts. Ideally, the factory should have designed tapered sleeves and rubber washers. That would prevent movement and isolate vibration. Unfortunately, that would drop the sub-frames .25" and require re-alignment, more assembly time, and increased cost.

This is akin to adding a bushing where there wasnt one previously.
