i am having a few problems with the rear shox`s on my rs200 replica

here is a pic of the top mounting points that are on my chassis at the mo

if i use these to hang my coil-overs of,the bottom of them wants to be right in the middle of the wishbone bottom spring perch`s.


if i use the orignal bottom mounting points on the wishbones i can make a mounting point on the chassis.

with the shox fitted into the lower mounting i have about 20mm clearance from the rim face to the spring.



which 1 would be best?
if it`s the orignal mountings on the wishbones at what angle would be best to mount it,vertical,angled 1 way or the other

sorry if this a long thread but i only wanna do it once and be sure it is correct,and suspension tech ain`t my thing
thanks

hi, vertical is always the best ,remember the group 4 escorts etc all had vertical turrets+dampers or escort the mk 1's!!! ford produced the turrets to gain better damping etc -so ! in my book vertical is best whenever possible,
---do we all agree???-lol

 

No real quick answer on this, the mountings depend on where the other mounting is and the stroke of your damper. I would firstly decide upon the wheel travel I can get/want and take it from there. Regarding mounting angle, virtually any angle is OK providing you aren't trying to bend the damper. Once you've found your bottom mount you need to locate the top taking into account the sweep of the arm through your chosen wheel travel. I know I've not given definitive answers but I hope it helps a bit.

 

so it would seem best if it was fitted to the rear of the wishbone (ala orignal) as apossed to the spring perch area.
thanks for your input guys

The angle between the shock and wishbone changes during suspension travel. The shock should be tilted so that this angle never goes over 90 degrees. Preferably it reaches the 90degrees at full travel and be at a minimum of ~70 at full droop. More tilt on the shock adds progression on the damping but makes it softer on the whole.
