Just home from Bedford and had a great day. Was very greasy so didn't get out of sport+ plus the fact I'm no hero driver!
The brakes need improving though. Braided lines and some good 5.1 needed, but what are my options for pads? It's my daily so I don't want a race spec pad. Just something with more bite and that doesn't need loads of temp to work well. Any suggestions?
Also, the brakes are grumbling a lot now. Not full on warped levels, so wondered if it was just pad residue that may clean up? Thoughts?
Sounds like you had a good time if you want to get out there again.
What went on the brakes? Long pedal?
We all have our own ideas about upgrades, and I'm sure others will say different, but braided brake lines are no longer the upgrade it used to be. Modern lines are reinforced, often with Kevlar which means you don't get the benefits you used to. Also there are that many scare stories of fittings coming off or lines being too long/short and snagging, I'd steer well clear.
Pads wise, the better the pad the bigger the difference. I would advise one of the Ferodo or pagid race pads. No good for street though, as they squeal and dust badly. M car sport pads are the obvious upgrade, but not hard track day proof.
I'm sure the shudder is just pad material deposit. Makes sure you cool the brakes well before pitting. Otherwise you can get pad shadow. It could be this. Some hard 60-5mph stops should clean them up.
It's been a while since I've tweaked anything so will take that on board re the lines.
Perhaps just a fluid change for now.
Pad wise I use DS2500s on my 182 but I've read these aren't great on a bigger car? I liked them though, sensible bite from cold and stood up to some abuse on track.
I know it needs to be a compromise so I'm probably in the "fast road" category, Realisticaly I'll only do 5-6 track days a year so road use has to come first.

FWIW I ran DOT 5.1 BF and m4 sport pads up front on my MPBBK'd m135i - worked well for DD, frequent "fast road" use and about same no of TD's pa as you.
I have a set m4 sport pads F&R to install on my m2 when stock pads wilt/need replacing.

So, the full story I got when there was that it was obvious I drive it hard and potentially track it. The tyres gave it away!
The Caliper didn't absolutely need doing but that was the easiest way for them to get the discs and pads done on warranty.
They warned me that getting another set won't be easy if possible at all.
The problem I went in with was the rumbling and vibration when braking. Pretty likely to be excessive pad build up on the discs.
I've used 2500s in my 182 on track for years and they've been great. M2 is a much bigger car though.
Good to hear feedback on the Motul fluid. That's what I am planning to use.
