Front and rear bumper swaps on Boxster S and Cayman S

[kidplatinum]

Hello All,

I am not a Porsche owner but will be soon, but before I decide I need some assitance on exterior styling

I was curious if the Boxster and the Cayman share the same platform. If so can I change out the front and/or rear bumper? I really like the Tech Art GT Sport bumper on the Cayman and Tech Art does not offer the Boxster that style bumper except for widebody kit. Does anyone know if the Cayman S GT Sport front bumper will match up to the Boxster, or does anyone know if Tech Art plans on producing a non widebody GT Sport front bumper.

Thanks in advance for the assistance
Mike
