not 100% sure
Hi Dominic and Andrew,
The lug width is listed as the same, but there still may be a size/fitting difference.
For rubber straps, the regular AT rubber strap is IWA 15761 and the Split Minute uses IWA 15881. I believe that there is a slight difference in how the straps fit at the lugs. I likewise would think that the parts to use the nylon/velcro would have a slightly different fit.
It might be possible to "force-fit" the strap, without perhaps a perfect curve at the lugs, and candidly I would gamble. Or better yet find a cooperative dealer who would allow you to try at the dealership (which might be difficult since it's a special order accessory).
Regards,
Michael
