Brake disc dimension info
RazMan - 15/1/11 at 02:06 PM

Following on from another brake related thread, I thought I might look at getting some solid discs to replace my vented ones. They are the 285mm dia Westfield vented jobbies bought from Rally design a few years ago. Standard (solid) Cortina discs are 247mm dia so I would need to change the caliper mounts too which adds to the cost of the change (discs are only £30 the pair though)

I remember from a while back, there was a link to a website that listed all of the different combinations of disc sizes, offsets, pcd etc etc and a number of discs are often interchangeable depending on their application. There is just a chance that there are some solid 285mm dia discs which I could use. RD list some but at £90 the pair + VAT

Does anyone know of a link to such info? Or (and this is a longshot) if anyone wants to swap their solid discs and caliper brackets I am all ears

Thats the kind of stuff Mal - ta muchly.

Incidentally I now know that my rear discs will fit a TVR Griffith & Chimaera

Unfortunately I can't find any solid 285mm discs as they all seem to be vented at that size

Do a check on the 406 coupe rear disc.

I think it is 290mmx10mm and 4x108mm PCD....

..or the Citroen C5 3.0l rear disc is 276mm x 14mm.

Close, but no cigar i'm afraid - the offsets and bore sizes are not right

If you give the rally design part number for the discs your after I can probably get them cheaper.

And I'm currently working in colchester so can save you Postage

RAZ, my contact says that the Rally Design website might be wrong on that price. Thinks it should be half that. He'll check monday for you.

Aha - that would account for the prices appearing to be twice as much as most other suppliers. If their 'each' price is actually a 'pair' price then I will put them back on my Xmas card list

Sounds good to me Ben - do you happen to know if I need a seal kit when removing the Dynalite 2 caliper spacers for the thinner discs?
