heterofrogs1 Posted July 2, 2025 Posted July 2, 2025 Any of you knowledgeable people able to help guide me in a purchase of a set of JR21s? I found this Z and I strive for the same fitment and the glorious concave cavernous width of the 19x11s. Alas, 11" width has been discontinued. Rim calculators suggest it could be a fairly noticeable difference, and we all know an inch can make the difference. Thoughts & opinions? Quote
Andy_Muxlow Posted July 2, 2025 Posted July 2, 2025 It all depends on the offset. I had JR20 19x11 on my last 370Z the offset was +25. So I had a 25mm spacer on to make them flush. 1 Quote
heterofrogs1 Posted July 3, 2025 Author Posted July 3, 2025 Thanks Andy. I think I'm getting lost on width & offset. So I think 19x10 ET20 (275/35) with 15mm spacer will be golden, at least for the rears. Then 19x9 ET20 5mm spacer (245/35) 🫡 Quote
Andy_Muxlow Posted July 3, 2025 Posted July 3, 2025 I would go 19x9.5 0n the front then no spacer required normally. then 19x10.5 rear. 1 Quote
heterofrogs1 Posted July 3, 2025 Author Posted July 3, 2025 Righto. 9.5 on the front, but it'll have to be 10" on the rear that's the widest they do JR21s 🫠 1 Quote
