Front discs
 
Before I dive in and buy new discs + pads. I’d like some help.
So basically, noticed wobble when braking and thought discs are out of shape.
Got the wheels off and noticed that the discs even tho bolted up tight seem to have some play. It’s not the hub as I’ve checked that.
Almost like the discs don’t sit right. I have classic swede coilovers on the front and super forma spacers. They are correct torque.
I don’t know what make discs they are. Any help would be good.

Solid or vented ?

I've had this problem once with a new disc. The machined back face of the disc is a tight fit over the edge of the hub, and the tiniest bit of metal burred over the lip or speck caught in the gap is magnified at the greater radius at the disc face.
Go round the edge of the hub with a fine file smoothing it off, and a small sharp chisel or knife edge cleaning out the recess in the disc, and try and feel that the disc really is clamping absolutely flush against the hub face.

If it still wobbles then the disc has probably been distorted by overheating, perhaps by a sticking or rubbing pad.

Sorted now. Took discs back off and spacers. Cleaned up better and refitted. 👍🏻
