Hello, are those 20's squared all around?
How much do they effect range? I assume it would be SLIGHTLY positive over the 21s due to weight alone, but not like it matters all that much to me. Wanting to pick some up myself!
The weight difference is significant, and if you are running around town I would imagine that it has to improve efficiency (and therefore around-town range). However, most people care more about range on the road, and there weight hardly matters - aero is the big deal. I don't think they help in that department.
The weight difference should also slightly affect acceleration. But it wasn't enough that I noticed a difference when I put them on my MYP. A previous set on my M3P did make just enough difference to notice; maybe because the M3P is quicker to start with? I am not sure.
What does squared mean?Hello, are those 20's squared all around?
What does squared mean?
Yup. And the factory Y wheels are square for 19" / 20", staggered for 21".Squared is same on both front and rear axle. Good if you want to be able to rotate tires all around.
Staggered is different. They can be different diameter/widths/offsets of the wheels and/or tires. Limits your options for rotating tires to side-to-side. Throw on some directional tires and you can forget rotating them.
