rear suspension
I know that this topic has been covered in other threads but I just wanted to double check everything.
Following my conversion from live axle to de dion, i'm now looking for new coil overs for the rears.
Front setup is cortina based with spax coil overs.
1) What spring rates are you guys using at the back? I will be using my dax for a combination of fast road use and track days (plus an endurance race
if i can get the thing organised!!!). Need the best compromise.
2) I am looking at using protech dampers - any feedback?
3) They have asked my what bump/rebound ratio i want. I understand theoretically what this means but what ratio is right for our cars? From the
research i am leaning towards 2:1. any thoughts?
4) at ride height the distance between the mounting holes is 10". what length damper should I go for?
any help would be great.
many thanks as always

What does the car weigh and what is the weight distribution?
I use 140lb/inch springs on my 7 which weighs 550kg and is biased roughly 50-50 front rear.
Dampers-wise, ask "procomp" on here, he knows more about protech shocks than most and will advise on rate ratio. In terms of quality, I
have no issue with them, they are certainly at the "good end" of the cheap damper market, better than most.
(and certainly better than the std spax offering! )
Damper length depends a lot on what things can hit at full bump and full droop.
Jack it up to where you want full bump to be, and spec the closed length of your damper a bit longer than that, then set it at where you think you
want full droop to be and spec the extended length a bit shorter than that, then get the nearest to that. You should end up with at least 2 inches
either way or you will be compromising handling.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

car weight is around 650kg - approx 50-50 wt distribution.
Thanks for the advice regards damper length.
