 Does not fit 986 Boxster S
 By Bfan, submitted October 22, 2013
 Comments: I had read some where that I could use this disk on my 986 Boxster S 2001, and it would give me somewhat more bite.
 It does not fit, the splines are slightly different. It is surely an excellent product for its use.

Update: Not so fast.Perhaps the MIT grad was correct?
 I bought and tested a 23(yes23,not 21) spline clutch alignment tool for a 1" /19/32" bushing.It is intended for a Ford Explorer. It fits my 2001 Boxster clutch plate and DMF perfectly!
Porsche are notorious for mix&match  so before you decide on this project get a cheapie tool and test.
  Surprisingly the Pelican rep was terse & unhelpful on this issue It would have been easy for him to have performed the same simple test I just made -and sold an $1800 Pelican "clutch super kit" !
