When you say are they fitted correctly, what are the issues you are talking about in terms of fitting mistakes?
Some of the issues. Referred to with coil overs being incorrectly Fitted is correct. This isn’t that the coil overs are at fault but often wrongly applied by specialist suppliers . if they only sell , or Offer sleeve over or coil over kits they tend to use them for every customer and it’s not always suitable and doesn’t always satisfy customer needs. 70 % of the kits we do ARENT coil overs !!!
we have seen sleeve over kits that are recommended to do 40 to 70 mm but the vehicle sat at 90 mm down . This means. Of course the kit isn’t fit for purpose if it’s too low and fully adjusted to the highest settings . Clients telling us of some specialists wasting 5 to 6 hours on an install ( that should take 90 mins ). Trying to overcome this issue , the answer would be remove it and fit something fit for purpose , but if you don’t have such a solution this is a problem . The lasting issue with a kit fitted and sitting too low is that you can statically set the wheel alignment to spec , but every bump the vehicle hits will throw the alignment out as the control arms arc to positions it shouldn’t go to normally . this can’t be fixed and will wear tyres . Who’s at fault here. the kit or the supplying company ??
the VW dealers of course are just the worst and we had a delivery mileage van in this week 60 miles on the clock and rear spring rubbers shot. Not fitted correctly . We had a brand new California with VW 30 mm springs Fitted. It was a T6.1 but springs were T6. And one rear was upside down and one front shock loose , the biggest problem was it was 80 mm down at the rear and 60 in front. , ??? NOT FIT for purpose as I said . who got the blame ? the product ! who was at fault ? the supplier !
The main point to hi light is that coil overs or sleeve overs ( cheap imitation of a coil over ) are actually called Ride Height adjustable kits by the industry. that means they are designed to adjust height !!!! It doesn’t mean they are there to adjust because 400 kilos of camper weight has been added And a saggy back end needs a pre tensioned spring to hold the extra weight up. This is the very reason that a lot of rear springs Break. When the rear springs are pre tensioned too far to lift a heavier vehicle than they are designed to carry they lose their tension or break ,
Must state that the better “ Ride height adjustable kits “ proper coil overs now have springs that can cope with the camper weight and can be adjusted to with in the spec that they are designed to do. Research well and always check for problems that clients are experiencing and don’t just listen to the good reviews .
