Joining the Porsche family, track rat style.

I talked to my friend with the 3.4 boxster that was previously a spec boxster. He works at Porsche of Plano and only works on race cars. He said that the synchros inside the 987 transmission are thicker, but everything else is the same as the 986. He swapped the 987 flanges for the 986 flanges because the 987 uses 10mm bolts and the 986 uses 8mm. The 1997-2002 986 inner cv joint is better for extreme angles and he's running 4 degrees of camber. He could have used 2003/04 axles (03/04 inner cv joints use a 10mm bolt with 8mm threads) but he felt the thicker 97-02 axles would last longer. The five speed is a good transmission if babied but you can't subject it to any kind of shock load. He uses the 987 5 speed because his car was already set up for a five speed, weight(6 speed is tough but heavier), and gear ratio.
