Hey there im interested in buying a set of door sills and i dont know the name of the company that makes them. If you have a source please pm me with the brand name thanks greg

 

theyrealuminum actually. Most people polish them or get them chromed. The scuff plates are ebcoming a fairly rare item. Ohh and theyre oem equipment optional from the dealer.hope that helps

 

OEM sills are S/S. I bougt mine earlier this year from Ray/Malloy and he assured me they were S/S.

 

really?
last time i talked to him he said there were two types actually.now that I really think about it. Ohh well ss will probably last better anyways.
how much did they run you? I know last time I checked they were going for about $150.00

 

If so, then they're not original factory sill plates. The originals are aluminum.

 

here only 148.00 and they are stainless steel...I got my mud guards from here too...

I've got an original 1993 Accessory/Option booklett that were given to prospective buyers. It lists the optional "Genuine Mazda Accessory" sills as S/S. l'll post the literature tomorrow.

 

I looked up my invoice. They were purchased for 144.00 on 02/03/04.

 

Well, it says they're stainless steel, anyway. I can see how someone could make that mistake because of the appearance, but the dead giveaway is the weight.

My 1995 came from the dealership with the sill plates, and I know for a fact that they're aluminum, since I had the RX-7 embossed logo removed and had them polished.

 

Well, if you're right.....then Mazda could quite possibly have a class action lawsuit waiting to be filed under the Deceptive Trade Practice Act and for False And Misleading Advertising. (j/k )

No but seriously, S/S can be fabricated in thin sheet form and can also be polished, can it not??? How did you arrive at your conclusion?

Ooops. Just read where weight was the determining factor. Interesting. About how much more would a S/S sill weigh than the aluminum sill?.

 

1) Stainless steel doesn't produce black oxidation like aluminum does when you use metal polishing compound on it, 2) the sheet metal specialist who massaged the embossed RX-7 logos out said they were aluminum, 3) I originally had them clear anodized (see picture below) before I decided I wanted them polished, and you can't anodize stainless steel to my knowledge, 4) they're not rigid enough to be stainless (you could easily bend one in half with your hands), and 5) they weigh almost nothing. Even thin gauge stainless would weigh more.

 

Perhaps the most evident truth teller is their ability to scrath so easily. I don't think S/S, regarless of it's thickness, would be susceptible to surface scrathing.
