BBS LM refinish

cant wait to see the finished product. nice work.

Thanks for the support

sick project

big time didn't know how much time was going to be needed before completion... the arches need to be worked still and I finally have the mgmt system on the way to make this happen!

A shot of the rear and the amazing amount of gap left behind by my CO's:

Post #30 I go over the grits I used and what order. Each wheel was about 2 hours of dry DA sanding, 6 hours wet palm sander, 4 hours of wet blocking, 5 hours of buffing wheel. I spent at least 8 hours on each center stripping and sanding to the aluminum. The barrels had a lot of paint and grime to remove as well before sanding could start... It took a long time.

Kinda hellish, but I couldn't afford to have someone else do these up and I love the way it feels now that they're nearly done!

did u wet sand at all or was it all dry?

[shortwave360]

hey
when u say u had to get the centers machined back because of the gaps for the mounting points,

is that for x10wide rim only?
or x9 as well? all sizes
does it apply to all types and sizes (17/18/19" and x9/x10/x11 width) of lm faces? From what I know all LM wheels are the same in design when it comes to the faces other then diameter obviously and offset. Some slight differences exist between the two offsets I have in the thickness of the face around the edge and depth of lug dish.

how much offset is affected by machining the mounting surface back?

There really isn't much material taken off the mounting surface that affects the offset. The recess meant for the head of the bolt was < 1mm. Where the offset really gets increased is when you mount the center in from behind the barrel so the thickness of the mounting surface "lip" bumps it out maybe 4mm. It was enough to not have to run spacers for my application and gives the wheels the old school look I prefer!

nice work on the wheels, i'm currently in the process of doing the reverse face mount on my LMs

i was just wondering what torque settings should the LM bolts be tightened to when re-assembled and in what pattern did you tighten them

It ended up costing me $300 for the machining and I figured it was about the same cost as spacers so... I have heard that some people don't machine them and still reverse mount them.

The arches haven't been completed yet, so the centers haven't been painted or bolted in fully. The project is kinda on hold while I wait for the rear bags and mgmt to show up. IIRC 15-20lbs is typical is typical torque specs. I start a star pattern and torque my first 8 bolts to half torque and then work the surrounding ones in at full. I would compare it to truing a bike wheel and working the exact opposite side of the wheel to avoid warping.

Got the centers back from the machine shop and the mounting surface for the faces are zeroed out now. A little before and after shot:

oh god...cant wait to see them done!

I know... I can't wait to get them finished either! I gotta find a place I can drive by with windows or mirrors. I may end up circling the block a few times.

here is a bit of a tease from yesterday after I mocked up the wheels from getting them back from tire mounting. My arches are getting pulled and flared... so the poke is only temporary.

these are looking awsome dude, doing a great job of polishing. just wondering but what grit of paper did you use for preping the metal befor polishing ?? Chris

Thanks! There were many steps to get them to this point. The machine marks on the inside barrels needed to be hit with 80 grit on a DA sander. From there I crept up to 120 using a palm sander with water. I continued to use the wet palm sander for, 220, 320, 500 and 600. I switched to using a hand block at 800 then onto 1000, 1200 and lastly 1500 before the first polishing compound. It's not easy and I wouldn't do it unless it's winter or you have another set of wheels to run. It gets addicting however to "chase the shine" towards the end and time starts to fly!

I have a bit of news... my tires finally made it in and I get them mounted this Friday. I have decided to wait for the rouge (polishing) compound until I get them back from the tire shop. Here is a little teaser for kicks:

ambitious... yes ... amazing ... yes. Fantastic work!

thanks brother!

Soda blast the centers and clear coat them for a raw finish.

I have other plans a little more glam...

wow looks awesome especially with the polished inside

It wasn't fun... but does look great. Danke!

loving the work will be keeping an eye on these

Cheers, I can't wait to post vids of them spinning!

wow, those look brand new

Custom is the word mang

sell them to me

$8k and there yours

Are you going to clear the inner barrel? I would suggest it as you'll have a bitch of a time keeping those from oxidizing over.

I need to investigate what the truckers are using on their trailers and aluminum accessories. They have a polish that seems to hold up really well and seal the metal for months on end. The car won't see rain very often and will kinda be a show car.

looks great! how much you got the wheels re polished for?

I bought the wheels for $2700 shipped. I have spent about $150 on tools and supplies. My buddies let me use their bench wheel to polish and after all the sanding was done I would guess it cost me about 40 hours of my life per wheel to get them where I would drive on them.
