Ive heard there may be issues with the wheel speed sensor when using the Mk4 hubs, but I’m going from memory and that may be rubbish. Something about having to splice the abs cable.

I’m using the fabia hubs with the golf mk4 / tt callipers

That’s good to know. I fitted new good quality discs and pads when fitting them and I'm really happy with the stopping power as is. The only downside in my opinion is that you can feel the extra unsprung weight with the handling. Very much used to it now and prefer it this way.

Best of both worlds then. Are you thinking of increasing the power? I’ve heard the lupo gti engine is very tuneable as an n/a?

Yes, I have an Ashley manifold which I got with the engine, intake the standard one is more than enough.... however we are still battling with a timing issue... it will get there.

This was my biggest worry, however there is a write up on here that suggests it does add too much, maybe I’ll look for some lighter wheels.

So a bit of research on this.
@A2Steve
The 312mm brake upgrade will add 2.9kg per corner.
The OEM sport alloys come in at 10.5kg
Now if I were to fit OZ Alleggertia HLT which in the same size are 6.35kg or the Enkei RP-F at 6.8
These would come in at 1.25kg and 0.8kg lighter per corner...

Completely non A2 relevant question but which Mercedes AMG are you sat in? I want one and ideally an E63s wagon but need more depreciation to make it viable.So it looks like 312mm brakes is are now going on

That’s not me but the power coater, isn’t AMG also a trim level now like s-line and m s sport. You know it’s cheaper to just burn the money manually right? My friend has an AMG GT. The thing is a money burning machine.

Yes AMG line is a trim, that’s what mine Is however actual AMG’s have that lettering on the storage cubby so thats a real one.

Yes OZ make some very light wheels albeit a bit expensive ?
Surprisingly my 18x8.5 3SDM’s are actually lighter than the sport spec 17’s.

Just weighed a standard SE wheel with tyre and comes in at 18.5kg! Wheels I have am not commit with are 10.3kg without a tyre....

Further to the big brake 312mm topic - I'm putting a pile of parts together at the moment going straight to 312 from the current standard setup. Probably the biggest question I have concerns the hub carrier / hub-bearing inserts when not using the Vrs component - I may have gone off half-cocked here, but is it possible to use the TT (8N) / A3 (8L) casting steering knuckle equivalent - ie and build up from there? The bit that is confusing me is that Golf IV 5x100 hub images have what looks like an ABS ring on the back of them that I don't recall from the equivalent A2 part. I noted @A2Steve 's comment 102 above about ABS / speed sensors and wondered if this is related, but wondered what the solution would be in terms of mix & matching of parts - ie. Golf IV (similar to 8L A3) hub carrier castings (which use different bolt-on brackets to locate either 288 or 312mm caliper) using A2 bearings, Golf IV hubs using Golf IV bearing / hub parts etc.? I may have completely mis-understood the whole concept though so open to thoughts and suggestions from people with a bit more knowhow.
EDIT significantly after the question above posted to avoid misinformation. In answer to my question in italics - no - don't do it like that!! The bearing diameters are different for the Golf / TT hubs and there are further issues relating to positioning of ABS sensors. The solution is Polo GTI / Fabia vRS hub castings with appropriate bolt-on caliper carriers and 312/310mm discs as these then bolt straight on to the A2 struts.

The golf mk4 style carriers bolt onto the fabia hubs. However I wouldn’t us the MK4 style hubs

Well after much waiting, work, children and being distracted. Angry bees engine issues are resolved, turns out that the engine I bought had issues prior to install, all my misfire issues etc were all caused by a single leaking exhaust port. This was very hard to diagnose due to all the work to do the engine swap and being convinced I had made a mistake some where. Well I didn’t my mechanic has finished finally (slow progress due to being low priority to save on costs) and she is running beautifully. It’s been such a long time I don’t even have a place to put it now, so need to sort that out…

To update this has I haven’t in a very long time, it turns out the engine needs to be rebuilt due to piston rings on one cylinder. I’m biting the bullet and doing the work. Hopefully this will all come together.
