Wheel Offset Question
So the style rim I really like are the Alpina XB7 20 spokes. The 757's look okay, probably my favorite of the stock offerings.
I see Savini is well liked here. Of those, I like the BM16s the best. I emailed Eric at Supremepower but haven't heard back. It's crazy times right now so it's all good. But when I went to search for Alpina offerings (23" is probably too big for me) I found these Mandrus 23's. I like these the best of all the ones I found. It says Mercedes exclusive but I've seen them on a Bentley, etc., and a wheel is a wheel, if it fits. These are the 22" offerings Size Bolt. ET Backsp Bore Load Weight 22x10.5 5x112 38 7.300 66.6 2000 33 22x9 5x112 35 6.400 66.6 2000 33 Those more knowledgable with offset, backspace, clearance, etc. will these work? Options are to go staggered, or a square setup with either the 10.5" or 9" I probably prefer square, one tire size, rotate easy etc. Also need to figure out the cap but that can be sorted out later. Would I need spacers, etc? Using a calculator if I compare: 21" stock rim (9.5" 36 offset): 9" Mandrus: new rim has 7.3mm more clearance inside, but but 5.3mm narrower on the outside. 10.5" Mandrus: new rim has 14.7 mm LESS clearance inside, and poke out 10.7mm more on the outside. 22" stock front rim (9.5" 32 offset) 9" Mandrus: 3mm MORE clearance inside, 9.3mm narrower on the outside 10.5" Mandrus: 18.7mm LESS clearance inside, pokes out 6.7mm more outside. 22" stock rear wheel (10.5" 43 offset) 9" Mandrus: 27mm MORE clearance inside, 11.1mm narrower outside. 10.5" Mandrus: 5mm MORE clearance inside, pokes out 5mm more Lookin at these numbers, it appears if I want to use the 10.5" Mandrus up front, I'd need a space of ~15mm to be sure? But then I would need a spacer in the back, and now I'm worried about camber, etc? All so confusing. Maybe 9" front, 10.5" back would be best. Last edited by jdang307; 01-07-2021 at 11:26 AM.. |

I’ve been interested similar styled wheels but haven’t come across anything off the shelf that fits accurately. Your calculations seem correct.
For example the front Savinis X7 owners are buying are 22x10 front ET15 so the Mandrus 20x10.5 w/ 15mm spacers would mimic the same flushness up front. If you use the same 20x10.5 out back you’d need a 10mm spacer to match the Savini 22x12 rear ET30 rear fit. You’ll have no problems running spacers that size as myself and others on here run those size spacers (although larger in rear than front) currently on our stock wheel setup. I’m curious to see where this goes. Keep us posted. |
