when you have found the caliper assembly open up the part number list so its full screen you will then see a blue arrow next to the caliper part number click on that, then on the red arrow at the bottom and you will see a new page open.
Yeah, I know, Jorge..and i feel very sorry indeed about that. Hope you be able to get rid of this difficult moment.
My Q4 is in its first stage of development.
Just installed a methanol waterinjection system, and soon we'll be replacing Turbo with hybrid T3/T4 one, plus chargecooler. The goal is to go for new forged pistons that allow us higher boost pressures. No we are running 22/23 psi and look forward to at least 30/35 psi.
Its necessary now to replace the clutch for a competition one, as after the methanol, the original fade up amazingly quick, as a sign of increased HP's. Now, because of the clutch, is not possible to go over 4000 rpms on full boost.To much power for the original Valeo.
I'll keep you posted.
