With the rebuild under way on my 70 911T I'm looking to add a more performance based shifter assembly in order to reduce shifting throw. A while back the transmission was upgraded to a 5spd 915. There are three systems that I'm considering:

Hargett - Looks like a well thought out system with an improved ergonomic shifter relocation. Also the most expensive and where the heck does the e-brake lever relocate to?

Wevo 915 - By far the most simple and elegant looking of the three. The adjustable spring tension seems to be a great idea for really dialing in exactly how you want your shifter to feel and there is a (so they say) 30% throw reduction.

Renn Shift - Pretty much all the same adjustability found in the Wevo with the addition of a reverse lockout. The concept of adjustable lever throw is very appealing.

What are your thoughts on these three systems?
