Hello Prime family- I need some help with my project as it relates to wheels. Considering mint Zanardi/Type-S wheels are pushing almost $5,000 these days and a set only comes up once or twice a year, I've been thinking about going aftermarket for the same look. My search has led me to the BBS RG-R wheel, which is damn close to the OEM Type-S.
https://bbs-japan.co.jp/en/products/1266/
IIRC, the factory Type-S wheel specs are:
Front: 16" x 7" Offset 55 mm
Rear: 17" x 8.5" Offset 60 mm
And they correspond to the following tire sizes:
Front: 215/45/R16
Rear: 245/40/R17
Sadly, it appears that BBS does not offer a 16 inch version of the RG-R, so my next best bet is a 17/17 setup like the 2002+ OEM wheels, but using the Type-S tire sizing of 215F/245R. My options are:
Front: 17" x 7" Offset 42 mm; 17" x 7" Offset 50 mm
Rear: 17" x 8" Offset 32 mm; 17" x 8" Offset 40 mm; 17" x 8.5" Offset 55 mm
I have to admit that I am still somewhat a noob when it comes to fitment and offsets, since I always used factory wheels on my NSX and never had to worry about that stuff (save for the 5mm spacers on my 02+ rims). Based on my limited knowledge, the set that would most closely match the factory steering geometry would be F 17x7 50 mm, R 17x8.5 55 mm, right? Still, both options are 5 mm smaller offset than the factory wheels. Does that mean that the outside rim of the tire will sit 5 mm further out from the hub? Is that going to be a problem with brake clearance (OEM 92 brakes) or rubbing? All of the NSX setups with this wheel in Japan use the 17/18 fitment and are set up for stance/looks, etc. I'm interested instead of replicating the factory suspension geometry as closely as possible for performance reasons. Any help would be appreciated!
