Rear brakes HiSpec upgrade - Request for information

[7SW]

Hello,

I am in the scope of upgrading the rear brakes of my 2005 S3 Cat.
The subject has been address many times but I need further information for being able to order the need part to HiSpec.
I already made the front axle with HiSpec UL4 + vented 260mm grooved disks.

Now this is the time to upgrade the rear side.
According to the information I could retrieve, the caliper should be UL2 SVA Sierra; piston size should be 38.6mm diameter.
As for the disks, which one (reference) to get from HiSpec meaning that their diameter should be 232mm, 10mm thick.
I would like to get grooved one (for having the same design as for the front).
What should I need to add for being able to fit all the stuff?

Thanks for your help.
Fred.

Just tell them what you have now and what you want to achieve. They should have all the necessary information.

Use the stock 232 discs you have if there in good condition, just deglaze prior to fitting the new pads.

The SVA version needs a little creativity for the handbrake cable but works well and if you have a tame machine shop to make some top hat bushes for the cable you will be fine.

Thanks for your answers.

I already did exchange by mail with HiSpec but I'll contact them directly by phone for getting more information.

Do the pads on the Ultralite 2 SVA calipers match the standard 232mm Triumph solid discs well? I ask because these calipers are just a generic Sierra caliper and I thought the Sierra use slightly larger discs. Is the pad therefore not close to the edge of our smaller discs?
