Tony and Bob,
Thanks for the additional information on the links and shock oil viscosity. I=
will be taking a closer look at those links. Regarding the shock oil, I hav=
e found I can buy motorcycle fork oil in 10wt, 15wt and 20wt on Amazon. I ca=
n=E2=80=99t honestly remember what I put in mine when I restored them but I d=
o remember saving the bottle as I didn=E2=80=99t use it all. Another reason t=
o straighten up the garage!
I also wanted to mention that I had a interesting issue in the past years of=
driving the car when the bolts holding the passenger side rear shock backed=
out. The first time I started hearing a clunk in the back and when I remove=
d the passenger side rear wheel I found that one shock bolt was gone and the=
other one was hanging on with about 2 threads left. I had used the original=
bolts and flat washers to attach the shocks. I bought new grade 8 bolts and=
split lock washers. The second time, I switched out the split lock washers f=
or internal tooth lock washers and put red Locktite on the bolt threads and t=
hey seem to be holding. One other thing is that after I sand blasted the fr=
ame I welded in one of the TSI IRS differential frame gusset strengthening k=
its and also the front lower control arm gusset bracket kits.
I can=E2=80=99t explain why the passenger side rear shock bolts would come l=
oose but the Locktite and internal tooth lock washers seem to be holding.

Hi all
<div><br>
</div>
<div>There are a couple of other options in terms of lever arm dampers and a=

<div><br>
</div>
<div>Firstly on other options, Armstrong also made a twin valve adjustable D=

le bit of relieving of the bracket on the 4a, more or less the same on the 2=
50/5/6 but not don=E2=80=99t that for

period and legal for regulations including FIA if that=E2=80=99s relevant.<=

<div>It=E2=80=99s a different. Deal for the TR4 (and earlier cars) in the th=

<div>Secondly, on oil you can use thicker oil but firstly it degrades over t=
