BBK (Big Brake Kit)

My ND just passed inspection yesterday, front and rear brakes are at a '2' so I am going to be replacing them very soon.  Was wondering if anyone in the club has been using any of the BBK's on the market or more specifically Flyin' Miata's LBBK?  If so, the next question is do you drive the car all year?  Asking as I have an opportunity to get the FM LBBK secondhand but not sure if the Wilwood calipers will be more prone to corrosion than the OEM calipers?

I called FM direct but they were not sure.  Colorado doesn't use salt and they have said they have never received any negative feedback from customers.  But how many of those customers drive all year?

Hey Jeff.  The Wilwood calipers are painted aluminum.  The paint stands up to brake fluid and Brake Clean so its very tough.  As long as the finish is not compromised the calipers will stay nice looking.  However, the hardware holding them together uses black oxide finish.  They will probably rust pretty easy.  

Unfortunately, I have no direct experience.  Many of my customers run them, but not many use the car year-round.  If you get them and the bolts start to rust, you can always paint the bolts with black paint.

@ken-hill  Thanks for your insight Ken.  Good to know about the finish on the calipers holding up and about the hardware.  My other concern is about dust boots, etc.  Do these type of kits have these or no as they aren't "typically" run on a DD?

Either way I think I will pass on these and stick with the OEM calipers.  One of the pros to these is the ease of changing brake pads but seeing that I don't track/auto-x it seems a bit overkill and I can spend the money on something else.  Plus, my OCD would kick-in and it would make me crazy that the front and rear calipers didn't match.  😆 

If any ND owners out there are interested, I can put you in touch with the seller.

There is no reason you cannot run Wilwood calipers on a street car.  Other than the salt mentioned above they will work just fine.

Agreed and if it wasn't my year round DD, I'd probably jump on this chance.  After further thinking I feel the pros don't outweigh the cons for my specific situation.  The biggest con being that salt exposure.

  • Here’s an interesting photo. This - why I waited for the OEM Brembos to come along.  That and I when I got my non Brembo/BBS/Recaro club l promised myself I would get everything it had, eventually.  I have everything now from that $4,400 option except for the side skirts and the Recaro seats (those hardest to find) but I’ve spent not even 1/3rd the cost:

Even tho the Brembos will work with the regular sized rotors, the pads are huge in comparison and thus a larger surface area. GWR makes a BBK for the OEM front Brembos too ($800) - light weight two piece fronts I think 1.25” larger in diameter- but my friend got it on his 2020 BBR Club and he’s having issues with them in terms of jerky and odd brake pedal feel, may be a quality control issue, not sure. But he’s not happy. Looking for an alternative possibly even tho I have what’s needed.

^^ my point being, that photo shows that some of the brake kits actually reduce pad surface area, or only increase it by a tiny percentage +3 percent for the dynapro 4 piston kit, +18 percent more with the dynapro 6 which is decent, but consider the cost.

I am not sure where the the Flying Miata little brake kit would fall on that chart, hopefully in the positive, for both front and back… plus there is the weight savings. Don’t know their weight specifically but a Brembo caliper weighs 5lbs, think the regular stock front caliper on all the NDs weighs 8-9lbs..

@stormnd2club The FM LBBK uses the 7912 pad and they list it at 7% smaller than the factory but having the same swept area.  After looking at the pic you posted though, that is comparing the 7912 at 5.0" to the stock rear pad at 5.4", the numbers FM gives.  It seems as though they need to update the site with numbers comparing that 7912 with the stock front pads as well.  Their Wilwood calipers are aluminum saving 5.45lbs per front wheel over the stock calipers and 3lbs over the Brembo calipers.

 

Next week, I might reach out to FM to see what numbers they can give me for the front pads on this LBBK.  That way I can report back with comparisons to the photo you posted.  One definite advantage to them is that you can drop replacement pads right in without needing to remove the caliper.

Ok cool. Def let us know. And yes that is one convenient & cool perk of having those, dropping the pads in 🙂
