I wanted to continue this thread after having a little more insight into the Stance + and other cheaper options , so yesterday I agreed to fit a set of Stance coil overs to a customers van ( he supplied them ) I wasn't keen to do it but thought that it would help me decide if these things are viable or not .
My findings are as follows and I wont comment on good or bad just yet .
1, In the box they do look good value
2, The C spanner is about as useful as a Chocolate oven glove
3, No instructions but there again not many suppliers give them , hard to know which way up the rear spring and perch go and this one didn't fit . SO -
4 , I had to take a grinder to the rear spring support as the adjuster wouldn't fit , Not a fault of the kit though .
5 , The installation went well no other issues .
6, Ride quality a little choppy and no refined damping here but lets be honest for the price ?? it is ok on reasonable road surfaces
7 I had the vehicle lowered approx. 60 mm so sort of in the middle of the range settings .
Now the troubled items for me .
1 the ANTI roll bar tie rod mounting bracket is lowered about 30 + mm , this has been done to allow for excessive lowering of the spring perch , but I am not sure if this would cause excessive horizontal forces on the A R B instead of normal up and down forces . I have had plenty issues with Race cars having this problem and the drop links and ,mounting brackets were breaking often.
2 The Anti roll bar link bracket isn't welded exactly 90 degrees to the locater plate that slides in to the hub . this means the bracket doesn't sit exactly as it should and could put a pre load force on the Anti roll bar . ( when the front wheels are heading straight ahead .)
3 The diameter of the front Stance Shock is only 50 mm and the standard original T 5 T 6 shock is 60 mm, so there will be a lot less oil inside which may cause premature overheating of the oil . ( shock oil can get as hot as engine oil in extreme cases )
4. The front shocks have a piston rod that is 3mm smaller in diameter than a standard shock . the front shocks take enormous forces on the shaft during heavy cornering and this is probably one safety concern . ( Stance 22 mm standard shock shaft 25 mm )
5 The Rear damper ( shock ) on the Stance kit had a shaft bigger than standard . On a non McPherson strut shock the shaft diameter is normally smaller as the bigger the shaft the more oil the valves have to contend with and more oil moving more heat build up /.
Important to note that one of the strictest Vehicle standards for Cars and car accessories is the German TUV . unfortunately shock absorbers don't need TUV approval according a large shock manufacturer I spoke to ( I haven't verified this unfortunately ) .
So to balance up the comments made earlier in this thread and confirm that you get what you pay for in life.
Don't know how even the Far east can make these things for this money ???
