Have you got a dial gauge to have a go at measuring the runout of the disc/bell? If not, happy to lend you one.

Yes, part of my cam timing kit. Thanks for the offer though.

I checked for disc runout today and one side has 0.003", the other 0.004". I'm yet to remove them and check for any runout with the hubs.

I had this vibration through the steering wheel (not the pedal) problem with the original Brembo discs so replaced them with the current Valeo ones. Pads are DS3000.

TBH, they probably didn't get the proper bedding in procedure being a track only car.

This makes for an interesting read...

Great video and result

Could it be a flat spot on a tyre?

If it was tyre related the vibration would be felt at a particular speed/s when driving. This only happens while braking.
