E63 (M6) new owner - tyre & handbrake question.
Discussion
At the start of the month, I traded my z4 in for a 2006 M6. First M-car, even if it’s the smallest engine of my current fleet. 
The front tyres are Conti Sport Contact 2, and 6 years old (but with plenty of tread), the rears are Accelera Phi - which I understand has the same tread pattern as the CSC2’s, but it’s plainly obvious to me they’re nowhere near as good at grip.
I’m a Michelin man at heart, and would like to put my preferred PS4S’s on the car, same as I’ve got on the 760, so I know the tyre already. However, they don’t come in the standard sizes for the M6.
Would you:
1 - MPSS in OEM sizes.
2 - MPS4S in OEM + 10mm section width (i.e. 265 f & 295r)
Having had a good feel around the arches, etc. I’m happy they’ll fit, and while there’s a very slight increase in rolling radius, it’s not enough to worry me. Feedback from current/previous owners (and interested parties) is welcomed!
Secondly, I’ve been driving the car in Manual mode, shift speed 5 as “standard”. When I stop at a junction & foot on brake, then release, accelerate, there’s no issue. If I use the handbrake, upon release & drive take-up, there’s a severe jolt/thump, which feels as if it’s coming from the rear, so I don’t think it’s clutch actuator/judder.
I’ve tried knocking it into neutral at the lights, and then releasing h/b, then foot on brake & into 1st and off we go, no issue, but that’s a bit of a PITA.
So, for any S85 owners/experts, what am I doing wrong please?

I have used Super Sport on my m5 for the past 5 years. Really want to try the PS4S however as you have found they haven't produced the correct size yet. So just stuck another set of Super Sports on this week. Stick to the original sizes tonne safe otherwise you will throw away £800 if rubs.
Banging whilst pulling away from a stand still is the release bearing on the clutch. Feels like it's thumbing at the back of the car.
