I had Prova units on my WRX before and loved them, so I splurged and picked these up through VividRacing:

They're great!

Any downside? Drill holes?

I see you got the ones intended for a Velocity Red car :)

Only downside was the $$... otherwise it was a 15 minute install:
1. remove the 2 hood bolts/insert hood shock plate/retighten bolts.
2. replace the factory bolt on the fenderwell with the included pivot-head bolt.
3. snap damper end onto pivot-head bolt
4. repeat for other side

You can have any color dampers you want, as long as they're red...

How much were these? I can get a kit for my focus for around $50. Might work for the 8 too.

Can you give us a part number? I went to their site and couldn't find these.

Thanks!

in my smallest unobtrusive voice... "And what do these dampers do exactly?"

These take the place of the cheesy 'hood prop' which I feel cheapens the whole look of the engine bay.

The Euro-Spec cars come with these, or it is a Mazda option - could someone in the U.K. let us know how much and who to order from?

Pretty please....?

UK cars come with the hood prop as standard. The "bonnet dampers" as they are known over here, are £99.95, which is more than a few of your $Canadian.

The hood of the RX8 is paper light aluminium, a fraction of a steel one, so its not going to kill you lifting it once a week or so to check the oil.

looks clean though...how fast does it come up??

does it make the hood bulge? i was hesitant on putting these on my miata a long while ago because of the chance it might bulge.

XDEEDUBBX: The hood doesn't fly up, but (trying to relate it to something you may better envision) it comes up a tad bit slower than the navi screen popping up... or maybe a moderate-speed garage door opening... or about the same speed a 90y.o. with a tennis-ball-outfitted walker would lift the lightweight hood, but much more smoothly and with no groaning or complaints about what they were doing there, lifting your hood for your lazy ass.

santino: I'm afraid I don't understand about the hood bulging?

$350 is a bit dear :(

I ensure it looks cool with a touch of Euro feel to it.

I am not sure ---- $350... another $100 or so can get me a cold air intake.

I guess that by "bulging" santino means that the dampers are trying to push to hood open all the time... so when it is closed there is upward pressure from te dampers trying to open the hood, so making it "bulge" up...

I kinda like the idea though... looks kewl. Does the hood slowly open up by itself? Or do you still have to lift it?

how does it close? do you have to slam the hood down?

If they really DO cost that much, perhaps Druck could arrange to get some for those of us that are interested? :)

My questions too.

Bulging: No. When closed, the shocks are exerting pressure parallel to the ground and towards the rear of the car... the hood wouldn't bulge b/c of that.

Opening the hood: You still need to reach under and undo the hood latch, then lift the hood about 4" before the dampers will do the rest of the heavy lifting... Their novelty is comparable to manual windows vs. power windows.

Closing the hood: Pull the hood about 3/4-way down w/one or two fingers and from 4" or so, push down gently to assist gravity so it'll latch solidly. Kinda hard to explain...

These may be really helpful for people with no opposable thumbs to use the hood prop. I have two, but I have to pace myself and reserve their use for important things.

UK dampers: If I had known... probably could've saved $100 or so... the things we learn...

I would be more concerned about bending or kinking the hood when first trying to close it... with the hood up, the strut support point is very close to the hinge point. If one of those struts siezes you could bend the hood...
Just a thought..

And then you get a nice new crease across your hood. :eek:

Oops. I'm with you, MadMAX, I wouldn't risk it. Call me conservative though!

So where is the Euro version? what is part #? how can we get some for less than $200?

Wait a minute. You said it got rid of the cheezy hood prop. but I see in the pic. it's still there. Hah, caught you! ;) Back to work and remove it!

If you don't mind could you post the extended and compressed dimensions from each end of the strut?

Why all the concern about damage?? There are a ton of cars in the market that come with these things instead of the cheasy hood props... heck my fathers 96 Explorer has them.

I don't think you actually need two given the light weight of the hood

I am working on a prop, obviously could not get the exact length made for Mazda, but rigged this up.

The strut is 'just a little' too strong, and the extension from the hood hinge gives it too much leverage, even with just the one strut.

Working on a kinder, gentler solution, I can get any size strut on sale at my local surplus joint for about $4 each!

Given that the hood is made out of aluminium it is more prone to damage due to flexing. There is also a crease line built into the horizontal center of the hood that if an undue amount of pulling on the front edge of the hood just may bend it!

That is exactly the reason the gas strut people I saw about this chose not to get involved.

Re-check who posted the cheezy hood prop comment vs. who posted the pics. ;)

Let me know what questions you're referring to and I'll try...

I can't make any measurements on the struts... I am currently a continent away from my car, serving a year in South Korea.

I thought that an earlier post mentioned that Mazda has designed struts that are being used on 8's in other countries? If so, then this should not be an issue unless there is a different hood being used as well.

looks nice, but I'd stick with the armbar..

Why spend 300 to limit your mobility to the rear from standing on the side. Don't you think it would get in the way o,f say, reaching in to access the rearward portion engine bay, for any reason?
