Now there's two parts to this; full aero (and ideally directional!) wheels, or regular fin/mesh wheels with optional aero covers.
I just love idea of designing a wheel, then to almost completely cover it with a over-sized hubcap. Its the unnecessary detail like a popup headlight, that is nothing but extra effort. Awesome stuff..
Originally, and in theory, the whole idea was totally functional - to channel air though the brakes; with wheel and cover setups as seen on things like a 935 Porsche or DR30 Skyline Silhouette..:
There were ones done by OEM's like Nissan, as used on the R31 Nissan Skyline Silhouette (1986 though 1990)..
..And Mugen (Honda) for the CF-48:
Then there are the range of aftermarket ones, such as the ones on the Hayashi Techno R mentioned above..
From Heroes Racing, to suit the CX-2 Fin and Mesh:
here, and here)
From Impul, for the Hoshino Racing Pro-Mesh wheels:
From Work; these incredibly rare covers to suit the E-wing range..:
skidmarks wheel and tire)
how about these relatively simple ones, marked Racing Saucer!
From BBS were these fantastic mesh styled ones..
Styled to very closely imitate the ones used on period BBS racing wheels..
From Rays Engineering / Volk Racing - for the Artisan Spirit Fins:
The high-offet 'FF' covers above also have really neat fastener-clearance cutouts in every fin..
Rays Engineering / Volk Racing C1..
Also from Rays Engineering / Volk Racing; were the covers to suit the 84C wheel...
These interestingly happen to look VERY similar to the SSR EX-C ones below. Would love to know more about this..
From SSR, to suit the EX-C fin and mesh.
Like the Volk 84C covers; theres multiple pieces, colours, great lettering, the small text around.. argh.. all good things. Unlike the Volk 84C covers however, I dont own a set.. and really, really want to fix that! ha
Both white and red covers were available with either black or red text.
Like Rays Engineering, these also weren't the only aero covers Speed Star made.
There were also these VERY rare covers for the SSR Aero / Development:
Better than that though, are the covers used on the SSR Starsorb wheels.
..and what is perhaps known as the Fushimi..
Dont have some fancy alloys with optional covers though? Well how about some period generic ones..
Dont have alloys? how about these Hella ones to pop on your steel wheels!
There were also a couple different wheels in this era that had small aero extensions to the face, such as the ZONE ARX below..
More of the Zone's above here.
Full sets of the aftermarket aero covers are now extremely hard to find, and I rarely see them for sale in any condition. 20+ years on, its not hard to understand that most would be damaged, lost, or even thrown away as they fell out of fashion. The search is worth it though.. my wheels feel incomplete without them.. :(
Thats it for pictures on this one anyway! At least now I can admire them all in one place.. :)
done! (that took a while..!)
Edit, December 2014.
Just spent another couple hours editing this post.. adding another 70 (!!) pictures I've collected over the last 18months. So sorry if it jumps around a bit when reading.. I'm bloody tired..
Thanks again to anyone who originally took any of the pictures above.
