Darwin will dial it in for you. Is it too firm for daily driving? Maybe once you dial it in, you can switch settings yourself for your sunday drives.

1 - I believe that BBS' barrels are fully forged unlike most company's 3-piece barrels which are roll forged. If I'm right, that means that they are stronger which is a good thing on a 20" wheel.

2 - you gain nothing by widening the front wheel. You are limited with tire sizing because you chose a 20" wheel. The widest tire that you can fit up front is 255/30/20. 265/30 is too tall. I wouldn't put a 255/30 on a 10" wheel. You could maybe fit a 275/25 or 285/25 but good luck finding that size and the side-wall will be super thin. You really have much better sizing options with 19" or 18" wheels....

3 - you gain little by widening the rear wheel. IMO the best tire size for 20" wheels is 285/30/20. That will give you the tallest side-wall while still fitting. 295/30 or more is too tall. A 10" wheel is perfect for the 285/30. If you go with a wider tire you will need to step down to a 25-series tire. I ran 305/25/20's when I had 20" wheels because I had a 11" wide rim. It worked fine and it's not a bad approach, but if I were running 20's again, I would chose a 285/30/20 tire and 10" or 10.5" rear wheels.

I hope this helps!
1. Thank you for your kind words And yes, very helpful post. Since I originally posed the question, I've decided to proceed with the rim rebuild. Someone else also thought that BBS barrels are forged. That did play in my decision, but I still decided to go with the rebuild so I will be forgoing that positive aspect. However, I've been running 3-piece 20" rims for quite some time now, and haven't had issues.

2. I am not a big fan of the machined finish that came on the LM-R's so one reason for the rim rebuild was to get a polished or chrome lip on it. Another reason was to see if I could max out the lip size. And with the latter, run a wider tire. I'm going to run a 285/25 up front, or at least try. Probably going with a Michelin PSS. The 285/25 gives a pretty close match to OEM diameter.

3. If I stayed with the 10", I probably would have run a 275/30. Other LM-R owners seemed to encounter rubbing issues with the 285/30. Plan on the 11's is to run a 305/25, but Michelin (so I've heard) is going to phase out the PS2's in that size before making it in a PSS. Currently, it comes in a 295/25 in the PSS variety, so I'll run that until the 305 comes out. 315/25 comes closest to OEM diameter, but I wouldn't be able to fit that wide of a tire under the fender with the offsets I want to run.
