Firstly thanks to Gaz for letting me buy these & Done for picking up and getting them to me.
Bit of a progress report
Sanded up & delivered to painter today. He's wanting to do an especially good job on them. Hundreds of hours spent on these already sanding & polishing lips. Started with 36 grit paper on the lips & worked all the way down to 2000 wet dry papers then autosole metal polish and 0000 steel wool then alloy polish. May try to get some 3000 & 5000 grit paper if anyone knows if this can be bought in NZ that would be awesome.
Bolts stripped back in vinegar, boiled in vinegar and baking soda, fully stripped to a black shiny finish then coated in zinc by Christchurch metal finishers. Better than new ones, will probably last a lifetime.
Sanded and polished hex caps and restored old original BBS centre caps with polishing tool, look like new & OG to.
Got a spare in the mix, is a nice lightweight 7" rim perfect for the boot, probably fit with a 195 tyre to make it even lighter
New tyres have been ordered from hyperdrive after lots of consideration I've decided to go 225/50r16 all round.
Had purchased 245/45r16 Nangkang AS-2 (only road tyre available in that size in NZ) but being unsure of Chinese tyres & bit of risk of clearance on M535i I have gone with Laufenn 225/50s instead keeping it closer to original
