F90 roll bars on, Geo setup with some actual camber. Corners much flatter and no more understeer on entry.

Big brake kit arrived. Struggling to find available workshops to fit them so it might be a while before they are on. Also have to solve a clicking sound coming from the front wheels at full lock and under load first. In the mean time heres a comparison for scale next to an Olympic plate!

Managed to get a slot for the M brakes at the dealer. Labour rate is eye watering but the ABS needs coding for warranty and insurance etc so its a pill I need to swallow. Then I feel im pretty much complete on my journey to create the love child of an Alpina B5 and M5 CS... Well maybe just some gearbox software from XHP once they support all the 3rd generation TCU's...

Lovely! Enjoying this thread. How much change did your exhaust mod make?
Thanks mate!

It made it authentic V8 sounding in my view. The X pipe smooths out rasp as well which is a bonus.

I think the size of the brakes just looks correct now. More so at the rear, where they are much bigger than stock. It's the same spec system Alpina fit to their B5 with the 621bhp N63 upgrades.

First driving impressions after bedding in are they have more bite when hot which doesn't fade off.
The dimpled rotors are noisier & kick up way more dust but that's why matte grey wheels are a thing right haha.

The recode has changed the ABS and the hazards don't kick in unless you are emergency stopping now which is really useful!

I'm slowly returning back to stock with a view to sell while in pos eq. I don't need such a big car anymore since up sizing the wife's. I would quite like a new RS3 but you cannot order them still. The market is full of over priced ones less than a year old. Seems quite dumb as there's more than 155 on autotrader sat there!

Sadly the one thing that's not for sale as 668M are the 550i unique / specific wheel. I do however have an exhaust X-pipe and Adjustable camber arms in the garage I need to get around to listing on ebay If you are interested?

£3.5k all in for the brakes and rip off dealer fitting and coding cost. I will be removing them for sale at some point soon via an independent. I've only heard of a hand full of people running these OEM upgrades in the UK so they are rarely up for grabs second hand.

Looks like I massively jumped the gun on expecting to be able to order an RS3 this year. I would be happy with nearly new as there's loads on auto trader, however they are mostly over list price still!

Brand new BMC drop ins
