After a season and a half in ITA and two blown viscous diffs, I put a torsen in my 1.6 Miata last summer. I've now been told "I won't protest you but, you're illegal". This past weekend I would have had to replace another diff thanks to the thumps in the rear during qualifying were it not for the torsen.

Is there any support from the 1.6 drivers or objections from 1.8 drivers to seeking to allow the torsen in the 1.6?

I did not change the lsd to get an advantage other than durability and I don't see any improved performance.

I'd like to hear some thoughts before seeking to gain this exemption.

Thanks.
