Split my 108's

[meh92]

The BBS 108's on my 2007 roadster were looking pretty rough. Only one shop that is relatively nearby was willing to split them and they wanted an astronomical amount to do the job. I decided to split them myself. After reading every online article I could find I gave it a try. My process was:

1. Soaked the bolts in penetrating fluid for 3 days. I used Sea Foam Deep Creep.

2. Set the triple square bit in the bolt and gave it 3 whacks with a hammer.

3. Sprayed the bolts again and soaked for a day.

4. Had a propane torch ready if anything wouldn't budge.

5. Used a 1/2" ratchet and a short extension to keep everything straight while I coaxed the bolts out.

Long story short, no snapped bolts, no rounded heads, no stripped holes. I didn't need the torch, either. It was nerve racking but I took my time, used gradual pressure, and they all came out. It took about 20 minutes per wheel.

Now they are off to the powder-coater for refinishing. I am going for an OEM look, not anything custom.

I've just had a couple of sets of wheels done (107's & MV2's) and have some 108's that need doing. Whilst picking up the wheels I managed to speak to the owner about the 108's. He wasn't phased at all about removing the bolts. He said that he just puts the wheels in his oven and then the bolts all come out easily.

After reading about how resistant most places are with split rims I was quite surprised at how blasé he was about doing them. He did say that they take longer to process so charged a £15 premium per wheel.

I was not so lucky. Three bolts would not shift, so I drilled off the heads in the end. Titanium is not easy to drill!
