Feeler GB - 280x10mm rear kit

[Brian D]

Here's the email I sent to Evan at Tischer. We'll see what happens...

Hi Evan. We're trying to put together a rear brake kit at R3Vlimited with Lee Vuong at Massivebrake, and we're coming to a possible stumbling block about the rotors. The number of the rotor is 34211160402 , it's for the Euro E30 Z1 model, late production. It shows as a good number on your part lookup system, with a price of 107.13. We've been told by another supplier that there are only 2 of these rotors in Germany, and there is word of another 2 in Canada. Is there any way of seeing if these numbers are correct, and if so, would the factory tell us if there are any plans to continue production? Lee wants 10 people to commit to a kit before producing it, so there will be at least 20 rotors needed, probably more with spares.

Any help you could give us would be greatly appreciated.

Thank you

See this drives home EXACTLY what I was talking about. Not just availability at this moment, but in the future as well.

I suspect they will want a big order to make some more, but then what happens in 12-24 months when they are out again and it's just you by your lonesome that needs a pair?

I am now officially only interested if something can be made to work with one of Wilwood's parking brake rotors for a less than the rear Race kit + emergency ring setup ($1300).

EDIT: Sorry, I just don't see the point of all this money and effort to base the kit around something that is hard to source and may be NLA at some point.

Z, I see you looking. If you say "I told you so", so help me...

EDIT: As I said in the current GB thread, the 280 kit doesn't fit my DD wheels, and since I'm buying the track wheels in my sig for, well, track, I can't buy another set of wheels for DD use if the brakes won't fit my current ones. I'm trying to see if spacers will get the profile to fit (I'm in Germany, Car's in Boulder, it takes a while to get people to help) but until then, I can't commit. I am interested to see it work though, but can't commit until I figure some things out. Serves me right for signing up before anyone back home replied to my emails.

On topic-- Well, crap. If thre are only two rotos available this might not happen at all. It seems like the wilwood parking brake rotor may indeed work better, but would the price be anywhere near similar? Wouldn't having 280mm front and 310mm or so rear be rather pointless/overkill? I do see the point of relying on NLA parts for a consumable kit, and that is a valid concern. I guess it depends on how many are available.

Parts fo 2002s are still available after production stopped 33 years ago. Z1 rotors will always be available as they are supported by BMW Tradition.

[z31maniac]

We both know that isn't a fair comparison. Z1s production numbers don't even compare to 2002s, aside from the fact Z1s were never sold here.

Either way, good luck with this one. I'm just going to save up for your Sport/Race kit then. Even though I think your front Sport plus a rear kit that could use the stock parking brake stuff would be the ticket.

The existing 300mm rear kit already allows to use the stock handbrake mechanism. Many, many hours were spent developping it. No need to start all over on another 300mm kit.

I am currently investigating with the help of friends in France in order to source aftermarkets Z1 rear rotors. There were many Z1 sold in France, and they certainly don't rely on dealers for maintenance.

BTW by "aftermarket" I don't mean crappy Chinese rotors. More like Balo or Zimmerman.

Good deal Lee. I really hope this kit comes about!

Awesome!

"Dear Mr. Lee, thank you for your enquiry. We can offer as follows:

34210017514 - brake disc original BMW part - 69,00 EUR each. Shipping costs for 10 pcs.:165,00 EUR"

So, Z1 rotors maybe are in short supply from dealers (and they are known not be interested selling parts for anything older than a leased car), but they are readily available from aftermarket and other reknown sources.

69€ is about $95usd
165€ is $224usd

Lee, that's the number for the early production (pre 9/90) Z1. Are we sure that has the right dimensions? I was looking for the later production rotor, which is identfied as "280 x 10 mm".

34211158338 is an obsolete part #
34210017514 is what I asked for - no specific size is mentionned - maybe for earlier cars

34211160402 I guess is for later Z1 post 1990

They sell for $95usd each plus $25 shipping per unit. Total is $120usd/unit. Which means it leaves me no room for risks, returns and my own time if i sell them $120usd. Either I find cheaper ones, or I charge more for them.

[Massive Lee]

Been investigating on European forums. Early Z1s had the same rear 258mm rotors as all e30s, while later Z1s have larger 280mm units. I will still investigate. But it does require ten participants to go ahead. Five ain't enough.

Hi Lee, I emailed the 514 number to Tischer, we'll see if we have better luck with that number. That would take the burden off you, we could order them direct from Tischer.

Edit, posted while you did. So the 514 number is no good?
