Fthe info I used was an article in Grassroots Motorsposrt magazine from
some time last year. It was a road test of a TR6 autocross car. I
beleive J.K Jackson made the sidebar comments about modifications, so if
you ask him or look at the article the info will be more accurate.
However - here's what I did to my TR4 rear shocks:
1. Removed shock from car. Maybe you can get away without doing this.
2. Removed the big but rather shallow nut - really a plug that holds in
the valve arrangement. Removed the valve parts - be sure to get them
all.
3. There is a center threaded stem - very small diameter - with a goofy
shaped item threaded on it. I turned this item down all the way. Takes a
little ingenuity to figure out how to hold the parts without boogering
anything up.
4. I mic'd some washers, found one as close to .070 as possible, and put
it under the spring.
5. I emptied old oil, reassembled, took out fill plug, and filled with
30 wt. oil from WalMart.
I hope I did it right. It only took a couple of hours. Hey, if you do it
and your car rides like an oxcart, suspension breaks off, has terminal
over/under steer etc etc please don't sue me, anybody. BUT -- I liked
the end result. I hope I did it right.
Good luck ! uncle jack
