Beauty, thanks guys, got some ideas now. I note that none of you agreed with the flap disc so that's good to know. 👌🏻

Here it is nice and clean and for shits n giggles he's the clearly structural piece of trim it was holding down. 😬

A lot of the trim pieces on the E39 are super brittle and just dissolve when you try to get them off. It looks like a previous owner has used what can only be described as an industrial construction foam adhesive to glue down a tiny piece of trim. Unfortunately this part of the tailgate is starting to rust because of how much shit is in here. This is stopping the water draining and there's a big build-up of dirt that is just staying wet. How can I remove this? Would a flap disc get rid of this? I think this car spent a lot of time inland. There's so much light coloured, fine dirt and dust everywhere. Sorry for the pic. I've cleaned this all up now so I'll get another pic of it clean today.

Yeah I reckon that's fine. Just watch the temp.

Hi, this was in the suspension and braking section. I have moved to more appropriate area.

Oh to have that much room! 😍

Welcome! You could always give it in and buy a BMW?

Hey Christof and welcome! Sounds like an awesome project! I'm not sure many of the regular users on here would know much about the HK but I could be wrong. Looking forward to updates.

Youtube mate. What 'in depth' are you looking for ?

😢

Snooze you lose!

Done done.

Oh, and I forgot that the main point of this topic was to reduce unsprung weight!

So, the wheels in question come with 255 tyres from factory but I guess semi's are usually a bit fatter, maybe that's too much for an 8.5. I'm currently running 245 front and 265 rear with Federal 595's on my 19's. There are no OE square setups so to run square I either buy 2 sets of OE wheels or get an aftermarket set. I was thinking about the OE 17's I have because I already have one set (17x8, 17x8.5) and you can get another set for under $500. I do have another set of the same 19's (I have a bit of a wheel problem) so I could put together a 19x9 square setup but I'm conscious of the cost of semi's this size. 255 square on the 19's would be pretty cool though.

Ok cool, because I do have some OEM BMW options for light(er) wheels. 17x8.5 M Sport wheels are 11kg and I could put 255's on them. Maybe that's an initial test.

Apex has been banned also.

Done.

To this day I find the stock R32 wheel size hilarious.

I've been to the Apex site at least a million times and never noticed that page. Much appreciated!

Enkei's are what I've been looking at. There were some Enkei 18x9's in my stud pattern that weighed 8.5kg's so similar to what you said. Did you notice a difference when switching to lighter wheels?

Nah, nothing formal, just open track days. Mostly small and tight circuits but I would like to get back out to Eastern Creek at some stage.

I've been reading a lot lately about unsprung weight and how beneficial it can be to reduce it for driving on the track, given my semi's only have another day or two in them I am throwing around the idea of some lighter wheels and a square set up. I have 265/35/19's and 245/40(?)/19 Federal 595's at the moment. The wheels and tyres are super heavy. I looked up my wheel weight online and got 14.5kg naked. Not sure if this was 8.5 (front) or 9 (rear) but that's a lot. I have also been reading about the benefits of a square setup. Much better rotation and potentially less understeer. When I throw these together I'm thinking about a 17x9 or 18x9 square (preferably under 10kgs per wheel) with 245 or 255's. I can get some cheap 17x8.5 BMW M Sport wheels, they weight 10.5 kg's each but at 8.5 wide could probably only get 245's on them? I know they come with 255's from factory but semi's are a bit chunkier. Otherwise it will be aftermarket wheels in a 9" width. Most of the other BMW wheels are heavy unless you pay a squillion dollars for some M wheels. Although, the E46 M3 Style 67's could be good but I'd have to buy 2 sets to square them up. My car has a tickle over 400hp and about to put an LSD in also, is 245 a little thin for a square setup? It kinda feels that way to me. Also, is there any tangible benefit to having 18's over 17's? Is the footprint demonstrably bigger? From those of you who went to light(er) wheels after heavy buggers, did you notice it much?

Nah its a server spammer thing Although, now that I manually approve all the accounts I can probably loosen up some of the restrictions.

Check out the pics in the NSW Events section!

Sweet! Any pics of SAU representing?
