What is the list's opinion on which is the best rear tube shock conversion
available for street and occasional autocross performance (Rimmer Bros
lists three different bracket types) and who is the best supplier of it?
What are your thoughts on Spax versus Koni shocks? I need to order all
components for a rear suspension upgrade and want to make sure I am
installing the best for my purposes. I plan to go with the performance
springs (lowered about 3/4") and urethane bushings. I also would like to
fit 16x7 Panasports so clearance may be a concern with any tube shock
conversion.
Thanks, Greg

Hi Greg,
I have fitted the tripple bracket set on my TR6, and when the car is
used for fast travel it's as far as I know the only set not producing
cracks in the chassis. I know many people do not like them
because the installation requires a lot of drilling and eventual
removal of the fuel tank, but on the other hand the set is the only
one that can cope with all the forces applied to the chassis mounts
without braking.If you don't use a roll over bar with fixings to the
wheel arches it is suggested to add an internal cross bar for more
rigidity.For more wheel clearance the outer bracket can be rounded
off a bit.The problems with the towers is that first you loose more
clearance with the wheels and second they tend to flex for and
rearwards, applying a lot of stress to the chassis.This set should
be reinforced with a tube leading from the top of the tower in an
plus/min 45deg angle backwards to the chassis to prevent flexing.
My car is fitted with Konis all around,but I would not recommend
them for racing as you will have to remove them for adjusting and
as far as I know they have full damping capability only in one
direction,compression. For fast road use it's no problem.
Spax can be adjusted on the car as long as you take care that the
adjusting screw is showing in the good direction when fitting.
As far asI know Spax damp in both directions, but no personal
experienceon that side.
If you lower your car you will have to make sure that you retain
full piston travel what might not be evident when using off the shelf
brackets. Please correct me if I'm wrong,you never stop learning.
Regards
Jean
