Does anybody know which of these two is the "factory original" REAR spoiler?

1 piece urethane wrap around

3 piece fibreglass wrap around

I only want to put whatever was factory available at the time of production on my -se, so I want to be sure I buy the correct spoiler. I have found one of each for sale, and don't want to hold up either seller waiting on me.

BTW, If anybody has the factory orignal front spoiler with driving lights - I'm looking for one!

Hopefully some of you true guru's will know the answer to this one!

Thx
Rob

 

Both I and my friend have what we both believe to be the factory option rear spoilers on our 1st gens and both of ours are 3 piece fiberglass. Neither of us are the original owners though. He bought his from a rotary fanatic who did alot to the car and claims it's the factory spoiler. I bought mine from a little old lady who bought the car new and didn't do anything else aftermarket. To me it seems like they are the fiberglass pieces but that would be the only time I've ever seen the factory use fiberglass. Don't go solely by what I'm saying as I'm not 100% sure. I would also like to know just to put my mind at rest.

 

3 piece. My 84 GSL-SE has been in the family since it was new.

3 piece urethane is the original. I have one in my garage, waiting to go on.

 

I thought the original was 3 piece fiberglass rather than urethane. At least that seems to be what mine is.

 

The original is 3 piece hard, not soft.

 

both were options depending upon location......Japan had the soft urethane only, Canada, I am not sure, but I believe the US had the FRP ones.

also the front one was never available over here as a factory option, but many people got them from aftermarket places and had them mounted soon after buying the car.

Bump for more opinions.

Seems like fibreglass 3 piece wins out right now, but according to kenn chan above it seems like either one may be correct.....any more experts out there?

 

BUMP again. I really need to be sure here, and even the long time forum members seem to have differring opinions.

Help me out here guys. I don't want to put anything not factory original on my -se!

 

Like I said I am not sure about the states, and I would vote for the fiberglass (FRP) as being correct for the states, but the reason they had the urethane ones over here was some dumb *** law that if a car wrecked and glass, plastic, or FRP shattered and threw debris it could only throw X amount of debris, so most makers avoided FRP over here for stock applications, with the new polyurethane type bumpers that problem was eliminated over here.

 

Mine is very hard Urethane.

 

OK here ya go guys:
A Mazda ad out of Rotary Rocket, 1985. (sorry my scanner isn't big enough to fit both pages).


The front airdam and rear wraparound spoiler were part of the "Mazda Finish Line" accessories.
Made of hard polyurethane and both were three piece (I've had two of the spoilers) These things are heavier than fiberglass and much more sturdier.

 

Priceless!!!!!!!!!!! Thanks!!!!!. Now the only problem I have is that I can get a 3 piece fibrglass, or ONE piece polyurethane. By the sound of it, the fibreglass is out, but the poly is ONE piece.

Any way you can scan the back half of that ad to see if you can tell if its one or three piece?

Thanks
Rob

 

good research by Whanrow the one piece sounds like the one here in Japan, maybe a JDM part?

you can tell by the picture of the back of the car on the left page that it is a 3 piece. you can see the lines where the parts come together

 

thats rather interesting. i didnt even know spoilers were a factory option!

 

any exterior factory options for the 81-82 year RX-7s?

 

i have some pics of the turbo model i can post in a bit

 

here is a stock turbo rx7

 

are you sure that thats stock? that looks like the old Urban silhoutte model front chin spoiler.

Whanrow, you must be giddy with excitement! (and not let my original post sink in ) reread it, and see what nick1 said.

 

Looks like the U.K. Elford Engineering RX Turbo, not a Mazda factory original.

 

The stock 12AT engined RX-7 did not have a front air dam or rear spoiler in any of the three models.

I agree it looks like the Elford which was a private development in the UK with a TO4 turbo and SU carb, and dolled up to look more powerful than its 160hp. It had numerous problems of quality control.

The other option being a UK car, is it could be a TWR version which was more powerful but the front air dam was similar to the Elford.

 

Nick1: You're right. I didn't see the fine little lines in that other photo.

RacerX7FB: Sorry, it didn't sink in as all the urethane ones I've been able to find are one piece, so your text was contradicting what I have been able to find out.

I'm wondering if SOME of the people with 3 piece THINK its fibreglass, when it actually a very hard urethane (which would have hardened more over the years).

Can anybody describe just how hard the urethane is? Is it possible to mistake for fibreglass?

 

I don't know man, I had to resand mine to get some chips smoothed out before I painted it. It sure as hell looked like fiberglass to me. Rock hard, and layered. I don't know, I've never worked with urethane before so maybe they are similar?
