The kit I was originally looking at from hi spec was
Rear...328mm disc 4 pot caliper with built in handbrake
Front...335mm disc 6 pot caliper

They say they will fit under my 17” RS diamond cuts
But still not got back to me having chased them all day yesterday

Thought about Compbrake but a lot of people don’t rate them
Cheap like wilwood kits
They do look good on their website tbh
Are you sure there brembo as they claim to make their own
