DBA 2 piece rotors/Calipers

[stiffy]

Chris,

I use the DBA 5000 series on the front of the Daytona, I have to skim about 30mm from them to make them fit, I am running 15" rims.

I am using Wilwood 6 spots on the front, much better caliper than the
standard VT/VE Commodore and a great range of pads form Summit.

I have found Hghtek Brakes in Moorabbin 9553 1160 to be about the cheapest and great service. You will need to order the 5000 series.

Cheers Stiffy for the info.
I have some Wilwoods specs on the short list, some 6 piston and some 4's as well that will all suit a 13.06 or 330mm rotor. These will fit under the 17" Vintage wheels I have ordered.
Thought it would be a good idea to throw it out there locally before committing to any gear from overseas. You just dont know who has what and if they are using them or not.
Im hoping to find some hats and rotors here and maybe grab some calipers from the US to suit. But will try to cover all options before parting with the hard earned !!.

Cheers
Chris

I don't know if this old chestnut has been discussed here or not. There were some engineers who would not accept Wilwoods because the calipers had no dust seals on the pistons. I raised this with the then RTA and was advised they had no issues with un-sealed pistons. Likewise my approving engineer was happy to approve them. That was some time ago when I bought them and they have been just sitting waiting to be fitted.

I again today read the NCOP for brakes and see that from Jan 2011 seals are required http://www.infrastructure.gov.au/roa..._01Jan2011.pdf (see 2.7.2)

Does anyone know the real state of play?

Peter, to get your answer (the correct one) ask your engineer. If seals are required in your instance then check with Wilwood. I remember seeing somewhere that they now have dust-seals as an option, maybe it's retro-fittable to your calipers?

What's the purpose of a 2-piece ?

[Aussie Mike]

The aluminum hat section is a significant weight saving over a conventional rotor. Also if you machine your own hats it opens up a lot of possibilities for different offsets.

Also a lot of 2 piece rotors are also set up as floating. The rotor can move side to side a little independently of the hub. This means you don't feel so much brake shudder through the pedal as the rotors warp under extreme conditions. Its usually a race track only thing since the floating mounts are another wear point you really don't need on a road car plus they can be noisy.

Cheers
