Hey guys, I upgraded my brakes with 6 pot caliper from porsche with 375 mm disks, and so i was wondering what it the max ET and J you use on your cars, because it seems that it should be under ET40 so it can fit on the calliper, but i don`t know if I can use 8.5J with ET40, because I don`t know if it will rub on the wheel arch or in the insede on the shock. Any help would be great thanks.

At the moment i`m running the stock wheels with 15mm spacers on the front and 20mm on the back, but there is a lot of rubbing on all four wheels.

I am running Alcon 6 pot 380 x 32 mm and run the following wheels
8.0x19 5x112 ET45 OZ RACING ULTRALEGGERA HLT
8X19 FOX FX004 5X112 ET45 73.1

No spacers but I do run negative camber on both front and rear wheels and lowered with coilovers.

Those big beautiful brakes 😍

...with Linglong tyres 🫣...
 
Non monsieur, je n'utilise que des pneus de qualité (actuellement Michelin PS4S pour les pneus de route et Michelin Pilot Sport Cup 2 R Connect pour le circuit)

or put another way PS4S for the road and Pilot Sport Cup 2 R Connect for the track and they both work very well under pressure.
 
These are very old photo's but it gives you an idea of the setup, I would also point out in parts of Euope you cant use this setup as it wont pass inspection, lucky in the UK we dont have the difficulty as long as the seup is safe.
