Brake rotors

Not listed with brake system. Look in the suspension sections.

 

TAV 45, 46, 49, and 50 (in the later TR SPC):

REAR SUSPENSION - BRAKE DISC (STARTING FROM CAR NO.75997) - Ricambi America, Inc.

 

Brake Parts for Ferrari 365 GT4 BB, 512 & Testarossa - Superformance

Rear's not too bad. Front -a bit steep.

 

Hi Scott,
This one is a bitter pill to swallow unfortunately. I spent a lot of time searching and xref the dimensions of the F&R rotors, but I found nothing that was close.

Rob Hayden purchased some in Oz for one of his TR's and they are available locally but the cost is a bit pricey. They were dimpled and slotted, a very swish piece of gear too.

I downloaded this quite some time ago. and the name of the brand is Protex probably Rob's source -

eziautoparts.com.au/pdf/Protex_Disc_Rotors.pd

From there I searched by dimension spec all over the place and had an offer from a specialty manufacturer in China willing to machine to spec.....but the quantities were no good for me..1k of each.


Still Looking!

Just an FYI
Got on the Protex site

DR12034 88 Testarossa -Front Rotor $627.05 each
DR12035 88 Testarossa - Rear Rotor $470.25 each
Thats AUD of course

 

china ? ? ?
and safety ? ? ?
2 worlds meeting - so nothing for me when it comes to brakes

 

give a call to bill at GT CAR PARTS 623-780-2200

 

Gt Car parts front $352 rear $333 this is for a 86 tr.

 

Peter, I know you tried to match some other rotors? You also make things like myself, Is there any rotors close enough to be re-machined or change bolt pattern?

You are definitely correct. I am not a fan of machining brake rotors as the hardening process does not penetrate much beyond the surface. Minimum specs is not just an issue for the hydraulics but also an issue for the surface as manufacturers understand surface hardening on grey iron.

These are items that do no have much global annual turnover with perhaps 30-40 a year being sold meaning no large or even small manufacturer really likes to produce them often, or if they do they better justify it with a substantial profit each to justify sitting on the remaining 400 for another 15+ years.

 

Nothing is even close. My company manufactures Ferrari rotors, but nothing for the TR yet although I do have them on the docket soon. Specs for Ferrari rotors are very different due to their offsets. Even if something were somewhat close I could not ever in the name of safety, due to surface hardening and required tensile strengths at certain areas, ever recommend ever machining something to work.

 

I think Brembo was the OE supplier. Whoever it was got tired of watching them rust on a shelf in the warehouse and about 10 years ago blew them out at scrap iron prices. I know Tirerack was giving them away.

I didn't buy any because I just could not picture anyone wearing them out.

I disagree about resurfacing them. I have done many and within minimum thickness specs it is a non issue.

I would not be surprised if the world wide supply is very small. All they fit is TR and 288. Considering what they fit the price isn't bad.

 

The only machining I was suggesting was maybe a little off the OD.

 

Years ago I saw a Super Vee formula car with VW solid rotors. They were all one piece cast iron stock VW rotors off a squareback. As per SCCA rules had to use VW parts. The hat part of the rotors had big holes swiss cheesed, Not the cross drilling. I thought that was kind of drastic and maybe unsafe? But I really don't know if it compromised the integrity. I know as a machinist I would not do it.

 

360 and 430 rotors are made that way.

 

You mean the radial section of the iron rotor is drilled?

 

Yup. Swiss cheese. So many holes it makes it difficult to mount on my 3 jaw chuck on the brake lathe. The ID has a bunch of half moon cuts in addition to all the holes so finding 3 equidistant spots for the chuck requires some fiddling around. Early cars didn't do it but after about 2002 all the iron rotors went that way.


They did the same to the hub area of the flywheel too but in that case because it is unsupported they warped like a potato chip. Only did it on the prototypes. Now they just turn bowl shape.
