Default SFI Flexplates what gives?

I want to get an SFI approved flexplate for my car when I do the converter next month but can anyone tell me why there are such large price differences between them? I've been LSx SFI flexplates anywhere from $85 - $250 and I have no idea why there is such a big gap.

B&M is the cheapest I've seen, $85, Yank is $10 more. I haven't heard from Greg yet about how much his are at FTI (I'm getting an FTI converter), does Yank seem to have the best value-to-performance ratio for their flexplate?

The cheap one is a CAT (china) very popular to rebadge or possibly a Pioneer, which they sell a lot of at the auto parts stores.

If it's SFI approved though, wouldn't that mean that it has been quality tested?

Probably means ONE of them got tested, which doesn't say much about the rest.

For reference, this is what the Cat Power looks like: Notice the trademark peanut shaped holes.

http://www.ebay.com/itm/GM-LS1-LS6-S...#ht_1681wt_778

This is a Pioneer brand thats rebadged a lot and also sold under the Hughes name for a lot more$$:

And the TCI appears to be unique from the rest.

Interesting, the one on Yank's site has the peanut shape and so does Circle-D...

Would that mean that the steel one you posted from ebay would be a better choice?

The Peanut shaped ones are made by CAT Power in china. Their SFI rating was legit when I checked when I was in the market for a flexplate. They are rebadged and sold by tons of vendors. I would recommend buying from a sponsor if possible. The links were for reference only.

Yeah, I was going to get the Yank with the peanut shape but after shipping it's cheaper to get one from Speed Inc. Problem is it costs $99.99 and they offer free shipping so I'm waiting to hear if they'll give me that penny lol

Question guys, obviously a flexplate is relatively cheap insurnace but should I spend $100 on a flexplate when my car only has 26k miles on it?

You will also need to replace the bolts.
Btw, my B&M didn't quite fit my converter. The elongated hole, or peanut shaped, caused some issues. I already had the converter bolted to my factory plate so that's not issue. The damn holes were off on the plate. I had two of them in with thread locker and could not get the third one in. I used a dremel and made them fit. But then had to chase the converter bolts. All in/under the car.
Bet your *** next time I'll make damn sure it all bolt togather before I put it in!
If your changing the plate, you will also need to, or should imo, change the bolts to the crank, and converter

That sucks. Maybe I'll just keep the stock one then and reuse the stock bolts

I don't think you can reuse the 6 bolts that go from plate to crank.

If my plate is fine with 26k I'll save the $100. I'm already $450 over budget on stuff anyway lol
