Look...it doesn't take a genius to work out that Porsche has crippled the Cayman S performance deliberately.

You can all argue your case until you're blue in the face. The fact is until the 911 does not meet Porsche's sales taget anymore and is regarded as surplus to requirements. Any sporting model Porsche puts out sans rear engined (CGT excepted), it will forever play second fiddle to the 911.
