Which Brake Discs ?

[jonb2010]

I've bought the Rally Design uprights from RTR and I'm waiting on the Hi-spec calipers. The problem is I don't know what discs to buy for the front. I've called Rally Design and they said that 265mm x 10mm should be ok but they may be 245mm. Not really what I wanted to hear

Anybody sourced their own discs and know what size / fitting I should be looking for ?

I bought a standard set of Ford discs and then had 40 grooves cnc'd into them. I was recommended to stick with grooves over holes, grooves dissipate heat very well without cracking between holes under extreme braking....

These are the ones I ordered, they are groved.

They also do plain discs.

These were advised by RTR, I also found the guys at rally design to be a bit useless when it came to advice particularly when it's there kit.

I also have the Hispek front calipers, and not problems with these.
I did have to use some washers to space the caliper a mm or so out
just to stop rubbing till the kit gets run in.

Do they do a drilled and grooved in that fitting ?

The first link is for the drilled and grooved
discs, the description states x-drilled.
but they have both holes and grooves.
Have a look at my thread I'm sure I put
pictures on there of the discs.

When I ordered them, there were pictures
Of the discs, a one line description with no
Picture is poor.

I got the info from the guys at RTR, helpful
As ever, the usually have them in stock give
Them a call.

As an add-on, I understand what venom means
About having holes in the discs and causing possible
Stress fractures. If you are using the car as a track car
Then this might be an issue, with the constant hard
Braking but for the majority of users these will last
A long time.
