I was investigating Alleggeritas for my Abarth 124 Spider. It looked like BBR could supply, but not the OEM et45 which I’d prefer. From memory they spoke of usually fitting et38(?) to the ND. My interest stems from wanting to improve handling, braking, etc by reducing unsprung weight, but I’m nervous about compromising that with a deviation from the OEM scrub radius.
Price has gone up quite significantly so that Idea is canned! I’ll stick with my Konigs, they’re a wider wheel anyway and just as light but also flow formed rather than cast.
