Probably old news, but thought I'd might share a facebook album from ISJ Engineering I just stumbled upon anyway. :)

Photos from LT5 calibration development 1987 to 1990 (https://www.facebook.com/pg/ISJ-Engineering-Ltd-802528229780798/photos/?tab=album&album_id=1460469727319975)

The car with AZ plates was probably coming from Mesa Proving Grounds, Some of those pics were from Monarch Pass hiway 50, 11.3 K elevation & Berthoud pass hiway 40 in CO also 11.3 K elevation, nice piocs

The guy behind ISJ Engineering I believe is Ian James, Lotus Engineer in the period of the LT5 development. I see Guy LaFalce have also commented the album.

Both mentioned in this article.
