Saw these advertised on Ebay:

thought about them for my 320is as breaking is a bit woeful since I played with the engine.

Good or bad idea.

They look good.

Check out godspeedbrakes, I was pretty impressed with their product line when I was in aflap about my calipers, they seem to have pretty good alternatives (haven't heard of WMS).

They say NOT for M3 - Will they fit the 320iS?

Yep, 320is only have 325 brake/hub setup.

Something to be aware of maybe is that some lightweight cnc'd calipers require regular rebuilds (I may be wrong). Cast iron road jobbies don't need this.

Not a problem if you like spannering!

I've been umming and arghing for months now about a brake upgrade. I have bought a 25mm BMC and braided hoses hoping that this would give me the extra firmness and bite i'm looking for, or will 4 pots be the only way i can get this car to stop well!

As a fellow 320iS driver... did U already rebuild the current (stock) brakes? That might be a tremendous improvement already. Combined with good fresh brake fluid, good pads and maybe steel braided brake hoses that should make a set of brakes that are quite ok for street (and occasional track day) use.

For this brake conversion... never heard of the brand and they only offer EBC pads which are not my favourites... if I'm going to do a brake upgrade I'll make sure to use a 'known' brand... at least I'll have more chance to get a rebuild kit in a few years... and have a choice of decent pads as well. Relatively cheap but quite reliable are the big brake kits from Wilwood, that would be the cheapest set I'd consider fitting.

 I am considering rebuilding my calipers as well, the 2 options i am looking at are:

1. rebuild my exsisting callipers and fit braided hoses plus 25mm BMC.

2. fit a 'big brake kit' with 4 pots(i have the Wilwood catalogue as well as bembos, hyspec and AP racing)

To be honest i am leaning more towards the rebuild option as i think 4 pots might be a bit of overkill for what i use it for and i reckon my brakes fully refurbed with the extra bits added will give me what i want, plus its a hell of alot cheaper!

Have you looked in the BMW parts bin? I am going to use E32 calipers for the M3.
You will also ruin your wheel offset with 4 pots (or other rims at all) to clear the two outside pistons.

Must say these calipers look like Wilwood replicas...

As suggested by Jeroen I would first rebuild my calipers etc. You'll be amazed what a difference it makes and if you are still not satisfied look for other options.
