Rear Spoiler Bolt on Type

[Phoenix]

Thinking of adding a Spoiler to my MC.

Could anyone advise on the Bolt on type of Rear Spoiler.

See there are lots of FAQ and How To's, for the stick on type, but none for the bolt on type.

I have seen a few different types from BMW. A very heavy one, (stick on), a Medium weight one that has 3 bolt on points, and a light weight (carbon or fibre) one with 2 bolt on points and sticky tape across the middle.

The sticky one looks straight forward, but the bolt on ones

Anyone fitted these?
How do you get template for the holes?
Pro's and Con's

Any help would be gratefully received.

there are 3 available from BMW:
1. the stick on AERO/JCW spoiler which is quite big.
2. the cooper S bolt on, sticks out a bit and takes 2 bolts (also uses double sided sticky stuff to secure it)
3. the smaller cooper spoiler, which alsos uses tape. This takes 3 bolts on early models but later on they changed this to a 2 bolt type apparently.

they did this so that they did not have to manufacture a boot with 3 holes for the cooper and 2 holes for the cooper S.
