I wouldn't say I've had any issues with my shocks, since swapping o rings...
Is there a simple way to know if your car is over sprung, under sprung, over damped and under damped, whilst on the bench... also what is there a correlation between the two
What characteristics would each of the four issues above give you on the track, my new copy of xxxmain isn't amazing at explaining the above issue!
Many thanks in anticipation!

Hmm, i'll have a GUESS, I've no idea if this is right though.
under-damped: car is sketchy and rapid to change direction
over-damped: car is lazy and sluggish
under-sprung: too soft, rolls a lot, lacks corner speed
over-sprung: too hard, lacks traction
No idea about when it's on the bench...

build it, run it.... then see how it feels, on the bench is way too subjective  |

Im guessing softer cap softens the pack a little and perhaps gives a bit more "spring" to the rebound?? |

Les, never played with the diagphrams, always used the standard black tamiya ones.
Have played with putting things above them to alter the pack and rebound, but now pretty much always run without (used to do that only indoors), and use a slightly thicker oil.
I would assume your right though, in that you could (subtley) alter how the rebound and pack works, as altering the rubber type/thickness will alter how they deform...
I would have thought softer would deaden the rebound though, less resistance to "spring" it back..??

Ok Ed cheers for that..out of all of the clubs memebers I thought you would have been the one to experiment,when you read some top drivers set up sheets they seem to specify type of diaphragm  ..but like you I have never bothered playing...Ill stick to what I know its confusing enough allready working out the best pack/rebound and spring combos  |

you saying I'm a fiddler Les?   TBH, Tam shocks work fine enough as is... never really had to fiddle too much with them to get them to work well!! |
