Hello,

I need to know the flank thickness of the standard front brakedisks. By the flank i do mean the part witch attatches to the wheelhubs. I can't mesure it myself as i've sold my front brakesetup.

Thank you in advance,



Mark

 

Does nobody have a set standard brakedisks laying around? I need this size to calculate the correct size of wheelspacers i would like to buy today. I currently have Godspeed brakedisks with a flank thickness of 15mm

 

I've bought an AP Racing BBK from Godspeed, the diskflanks of these disks are 15mm thick. This means i will need to buy different wheelspacers for my Group A (ET33) wheels. The original brakesetup has already been sold. So if someone can mesure this for my i can order the correct wheelspacers.

Thank you!

 

Nobody?

 

15mm ?!?!?!?!?!?!?!

they should only be about 8mm thick from what i can remember mate, possible even thinner than that

your wheels are going to be MILES out

 

this site has a LOT of useful info......

Yes they are, in my case not a problem as i run group A (ET33) wheels. The problem is that i don't know witch wheelspacers to use to get to ET15-ET18.

Thank you! Pity that the size needed is not quoted.

 

No one?

 

Really desperate to find this out.....

 

I will measure it today if you still need the info

 

That would make me very happy indeed! Thanks!

 

If you're saying you have spacers built in to the bells of 15mm, that is perfect to achieve the offset that you want with ET33 wheels. The higher the number, the more INSET the wheels are, so if you have 15mm spacers, then this would make the wheel offset equivalent to ET18 (subtract the spacer width from the wheel ET to get the new ET), which depending on the width of the wheels, is perfectly adequate (unless of course the car is already a wide-track Grp A car, which is what the ET33 wheels were designed for) .

So in answer to your question, another set of 15mm spacers should do the trick, but you will need these front and rear. Eibach do some this thick and Cossymad off the BB can supply them if you can' get them in your country.

 

Thanks for your reply, i'm not saying that the bells have 15mm spacers but the bells are 14.5 mm thick. Thats why i need to know the size of the standard disks to calculate what spacers i do need.

To achieve the correct offset that you want with "normal" thickness bells, you need 15mm spacers .

 

Flank thickness on the ones I have here is 8mm

 

Thank you! This means i will have to buy 10mm spacers at the front and 15mm at the back! thank you very much!!!

 

Mike, how thick are the original AP bells?

 

No problem
