yes it will fit on top of a k11 spoiler with just a strong adhesive,or if u mean on the car its self ,then it wont as i got 1 and when i put it upto the boot it sits to far back which will stop the boot from opening
You can fit one of the curved boomerang looking saxo spoilers on top of a micra spoiler which should eliminate the problem b47to mentioned. Someone has pics on here but not sure who. Looks good too.
