Replika R241 Wheels

[rob_ns]

I haven't noticed this mentioned much...
As the R241 look to be directional (similar to the Tesla Induction and Uberturbine wheels), are they a left and right pair or, like the Induction, are they all the same and end up aerodynamically shaped on one side of the car and opposite on the other side? I'm assuming the latter... Admittedly my (lack of) knowledge of aerodynamics and vehicles comes largely from watching F1, but maybe there's something to it? Or maybe it's just a drop in the bucket of efficiency? Seems odd... especially when even the Gemini wheel covers, as well as the Aliexpress "fake uberturbine" wheel covers are made in Left / Right pairs..

Obviously there are practical wheel-rotating considerations (especially for RWD), but with aero, range, kWh/km efficiency being relatively important metrics to both ownership & marketing, I'm surprised it's not talked about more.

Mine are all the same, they are not different on both sides. Maybe they should but they are not. I have no idea of the aerodynamic difference.

I don't think directionality makes any meaningful difference. The spokes are not really shaped like blades in the sense of a fan; they are flat on the back, and remember the pressure is behind the wheel in the wheel-well.

Adding my Space Grey 241s to the mix with a side photo profile.

They are 19s

and front side profile

Is yours 9.5 or 8.5? looks more concave

9.5

Just ordered these 8.5 for a MYP. Should be here sometime this week

For those of you who mounted Replika 19x8.5 wheels, what offset did you end up getting?

edit: do you reduce offset (to +40?) to keep the sidewall position similar to OEM 19x9.5+45, or should you keep the offset the same (I'm assuming this keeps the contact patch the same?)

 

[canYdan]

turns out that many of the Replika models in 19x8.5 size (e.g. R263) ONLY come in +40 offset

To prevent the 'sticking' I spray a bit of white grease on the mounting face of the R241 before putting them on the car and they come right off each spring. I have two winters on them ( with Michelin X-ICE ) and first car I owned where the winters look as good or better than the all seasons ....

The offset is away from the center line of the wheel, so reduce.
