I was still able to adjust my coils after 15 months . However by then the drop link bracket on the front had snapped which is common if you're running uprated ARBs (as I seemingly found it)
However I kept my undercarriage and arches very clean compared to most people maybe that's something to do with it?
I guess it's all personal experience and opinion really.
Are you sure the lowest was actually the lowest? As theres no way if fitted correctly the JOMs would be higher than the Eibach springs!
The GTI and 1.4 is ultimately the same chassis minus the engine weight differences and what not
Here are how my JOMs sat.
On 17s with 225/45 tyres.
rear adjusters still in, about 2/3rds of the way down.
Fronts at lowest possible setting.
Here's my car on Eibach Sportlines
Basically same angle.
Same wheels
Same tyre sizes.
