Bob and Charly,

=20

Thanks =E2=80=93 It crossed my mind about potential rear frame damage =
with the tube shock bracket when I was inspecting the rear shocks.  Not =
a lot of support there compared to the original lever shocks.  So, with =
your and Charly=E2=80=99s comments, will likely refit with adjustable =
lever shocks for the rear.

=20

Appreciate both your and Mark S=E2=80=99s comments on Delrin/Nylatron =
which is also helpful.  =20

=20

Hope to see you at VIR in March/April.  Will not be driving, but will be =
up to watch.

=20

Thanks you,

Hi,

=20

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

=20

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 problems with the conversion shock setups out there and you risk =
frame damage running with those shocks. I can write a lot on this topic, =
but unless you can verify the action of the bump stops AND secure the =
shocks via rod ends, I will guarantee frame structural failure over =
time.

=20

So - get a set of stock Armstrong lever shocks for the rear and get =
nosimport.com (worldwide autoparts in Madison, WI) to rebuild them as =
adjustable and 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 suspension 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 differently.

=20

Delrin is a trademark, I believe - the material is the same as Nylatron. =
You can verify by looking at the durometer ratings.

=20

Regards,

Bob Lang

Quick question (maybe?).   I am replacing the existing Koni front =
adjustable shocks (PN 80-1784).  Bushings are worn out as likely are the =
shocks. Same with the rear adjustable SPAX shocks on my =E2=80=9969 TR6 =
racecar.  I am more familiar with Bilstein, Koni and MCS. =20

=20

Any preference?  Spax and Gaz are unknown to me, but the external =
adjuster is appealing compared to having to remove the Koni=E2=80=99s =
every time I need to adjust the suspension.

=20

Using the =E2=80=9Cwhile I am in there=E2=80=9D approach, I will be =
replacing all the front/rear suspension bushings.  Have purchased =
Nylatron bushings.  Cannot find Delrin products for TR6.

Thanks,
