[Fot] Fwd: TR3 rear shock conversion

This almost certainly boinked since I forgot to trim off the extra bits. 


The construction has a lot of limitations. Modern racing shocks have precisely controlled damping that doesn't change much as the shock is stroked repeatedly. They use sealed air chambers or other means to prevent gasses from being introduced into the shock oil, the stroke of the shock is full travel so the damping in both directions can be controlled effectively, and the oil volume is relatively large so it doesn't heat quickly. Lever shocks have small oil capacity, a very short stroke (amplified by the arm) no gas/oil separation, and very limited control. The end result is a shock that looks completely inconsistent on a shock dyno. 

Fortunately our cars are equally unsophisticated in almost every aspect of suspension, steering, and braking. In other words you can't tell how badly they suck (or how much less a modern shock doesn't) because everything around them sucks. 

Bottom line to your question, tube shocks out perform them in every way except that you don't already have them on your car. 

There is a reason why you can get around a typical race track faster in a modern grocery getter than in a vintage production racer. That reason is EVERYTHING.
