 Full disclosure - I use Nylatron for all my bushings except the upper cont=
rol arms are heims joints (and adjustable). The upper a-arm bushings really=
 get beat and the metal is "just better".
I'm TR6 all the way.

  Hi,
Go with the Koni shocks in front. The SPAX shocks work well, but the gas le=
aks out and they become "just shocks" and without the gas, they can foam wh=
ich effects the shock efficiency over the course of a session. Or plan to r=
eplace the Spax every two years, plus or minus.

For the rears, unless you converted to a coil over setup and / or tie your =
shocks to your roll cage GET RID OF THE TUBE SHOCKS. I have seen a lot of p=
roblems with the conversion shock setups out there and you risk frame damag=
e running with those shocks. I can write a lot on this topic, but unless yo=
u can verify the action of the bump stops AND secure the shocks via rod end=
s, I will guarantee frame structural failure over time.
So - get a set of stock Armstrong lever shocks for the rear and get nosimpo=
rt.com (worldwide autoparts in Madison, WI) to rebuild them as adjustable a=
nd you get both a workable, reliable setup and it will work without messing=
 up your frame. Unless you do stupid things like I do and bottom the suspen=
sion and break the frame, but I digress. I've run the Armstong adjustables =
for a long time and they work great. With a little tuning, you can get rid =
of the rear squat when you tromp on it, Makes the car handle completely dif=
ferently.
Delrin is a trademark, I believe - the material is the same as Nylatron. Yo=
u can verify by looking at the durometer ratings.
