thanks for that bodsy think ill go down that route now, is there a need to change the rears as they are new as well because im 99% sure the wobble is coming from the front end of the car

Is there a Need? No, but having run my car for a couple of months on the front V8's only, (which improved the braking instantly) when I did the rears, it really made a difference overall.

My recommendation would be all, but if you only do one set, it needs to be the fronts first.

Check all the wheel bearings and bushes whilst you have it in the air as well, including the drop link bars.  Bodsys Brake Bible

that's what route I went down after the new discs bodsy I changed 2x front wheel bearing, 2x front sway arm bushes, 2x front upper ball joints, 2x front lower ball joints 2x front drop link arms and check all rear bushes in front and lower arms!!
Still no change

The car doesn't do it when it's cold eg when the brakes are first used

That's cos the discs are cold and haven't distorted. Once they build up heat they move which points to something seized. Once a disc has distortion it will never go away so replace them along with the calipers. If you read back to the beginning if the thread, it was suggested you check runout or disc distortion, if you haven't then you will keep chasing your tail.  2x TDV6. SE and HSE.

I've ordered the brembo v8 conversion today with new caliper holders, will I need to order new calipers as well??

If the kit is just the brackets and bolts then you need pair of discs, set of pads and two calipers. 2x TDV6. SE and HSE. Both returned to sender with issues👀

It comes with new caliper carriers, brembo discs and pads I was under the impression you left the original calipers on the car

If the originals are Brembo then yes, but then you wouldn't need the kit.....so two calipers needed. 2x TDV6. SE and HSE. Both returned to sender with issues👀

I've just spoke to advanced factors and the kit contains brembo brand discs and pads for non brembo cars and they will work with original calipers just need to change the carriers

🙈 don't see the point in that. Having fitted a Brembo kit to our disco, which meant fitting discs and new calipers I m lost as to what the point of fitting discs and pads but retaining original calipers as they don't have as many pistons.

^^^ - agreed. Surely the point of 'upgrading' to Brembo's is for the increased stopping power of the bigger calliper/more pistons. ON THE WAY: BMW F21 M140i

The disks are bigger than std, the caliper carriers move the pads further out, so braking power is improved along with cooling on the bigger disk.

This is the setup on the V8 (Petrol) RRS and D3.

There is another mod you can do which requires changing the calipers, and using the setup from the 2010 onwards RRS/D4  Bodsys Brake Bible

That's the way I would go, bigger discs with two pot calliper makes zero sense, and doesn't increase braking efficiency, so having bigger discs is only for heat dissipation which no one needs unless towing down hill a lot  2x TDV6. SE and HSE. Both returned to sender with issues👀
