AMR Engineering coilovers

[rr06rs]

Has anyone ever heard of these? I actually just signed up for the DG group buy and then a little birdie brought these to my attention. The first thing I notice is the pillowball mounts with independent standoffs from the spring hat, which the DG koni setup has but I just don't know if the valving and springs are on par with the tried and true koni/hypercoil combo? Thy also have no helper springs. How much difference do helper springs make? I notice the are on all the high end units like Ohlins, Moton, etc. Also, I was TOLD that an actual Ohlins rep tested these and stated they were the best they ever tested outside of the Ohlins. I'm still going with the DG koni setup regardless. I was just curious to know if the 2g guys knew these were out there or if there was another reason nobody's running them?

Actually, I did find something on the makeup from who is supposedly either a Penske or Ohlins rep:

AMR Civic Strut I took a look at a McPherson Strut at the request of Andrew Reyes. Latter I found out Mr. Reyes is actually the manufacturer of struts and shocks. His web sight is found at: http://www.amrengineering.com/index.html The unit Andy sent me to look at was as raced on his personal car. It is a mono-tube all threaded steel body. Take-apart design with a 8 position rebound adjuster. This particular version tested has an inline separating piston. Dividing the Nitrogen charge from the damping fluid. (This is my personal favorite if package length allows it) It has a 44 mm internal bore size (same as Ohlins) And uses a steel piston with an O-ring backed (bore) sealing band. Just like the big guys Penske and Ohlins. The working piston resembles an Ohlins. And use Deflected disk technology. Leading to easy tuning and calibration by the owner (if he has the skills and tools required). The shims are metric sizes with a 12mm center hole. Look like they could interchange with Bilstein or Ohlins. This unit was assembled using lock-tight and did require a small amount of heat from a propane torch to disassemble. But this practice is quite common in the shock industry. As no manufacture want to be responsible for strut parts under high pressure accidently becoming loose. Or having an inexperienced user try to service the unit incorrectly. And have it release its contents in your face. Do not take this lightly_without training and proper tools. Do not attempt to service or tune a gas shock! The quality and workmanship of the working shaft and shock body bore seem quite good. And appear to be a good value. The shaft seal it self is one I have not seen before. And has a bit more seal force drag than the high end players. But it appears to be of long lasting material. And does not exhibit the low shaft speed sticktition problems I have found in other struts in this price range. The adjuster is quite effective. And covers a large range with nice linear steps between positions. Andrew Reyes appears to be a hands on owner. Who is not only a club racer. But is headquartered here in the USA. And is personally committed to his products and service. You will that find this in the shock world today! The shock was easy to work with. And is of good quality. Add to this service and sales in the USA. My feeling at this time. This unit will be a hard one to beat! And I can not wait to take a look at the AMR Struts for the AW11 Submitted by Alex Szilagyi

Anyone??? Well now I'm getting curious....hmmmm....

Recieved an email from Andy the owner who advised they use Hyperco springs with Swift if requested. I'm very interested in these after hearing this...

Can ANYONE shed some light on these???? Opinions are fine too???

I'm still trying to figure out how they created an SA (rebound-only) non-inverted monotube....

No experience with these. A little intriguing but keep in mind, looking similar to or interchangeable with Ohlins doesn't mean it's going to perform like an Ohlins. If you're on the fence about these vs. the Koni-based coilover all I can say is that Koni has a long standing history of being the best option for our cars. It would take a lot of real world testing and positive feedback from suspension gurus in our community to sell me on the idea that these are a better option than the Koni-based coilovers for the 2g.

Also the top hats are not ideal since the bearing is mounted below or flush in the plate. It will cause you to loose travel in the front and you have precious little travel up there as is.

 

[snowborder714]

There also seems to be a lot of room between the upper spring perch and the bottom of the hat, which will also rob you of travel.

Note, also, that it's a monotube with floating separator, so the piston can't go anywhere near the bottom. Odds are, it runs out of bump travel inside before the hat design becomes an issue. Not that this is any better; I'm just explaining why Andy might build them that way.

One of the reasons a Koni with a well-designed hat and plate is so good for a 2G is because it's a twin-tube with a compact foot-valve. Maximum travel.

As to how AMRs can be rebound-only SAs with the adjuster at the top ... well, I was being an idiot last night. It's an upright monotube with no canister, so (obviously) all the action is in the piston-head. These shocks simply have two sets of low-speed bleeders. They can build them such that the adjuster only alters the rebound bleeder or that the adjuster alters both sets of bleeders in parallel. (Yes, I suppose that they could also make you a bump-only SA, but they would also laugh at you for even asking.)

In general, and as I said in a PM to the OP, if you're in an adventurous mood and want to try something new and different, go for it. If you want something that is absolutely tried and true, then go with the group buy.

O, I'm going with the DG Konis, hands down. I was just gettin some opinions.
