Hmmm, that’s odd.Just got my van back from Bognor Motors with my 15mm rear spacers and got them to raise me up 20mm after snapping 2 springs in 18 months!
It seems that being 70mm low is too low for my KW1's to last.
I'll be interested to see how you get on with your STX, as I understand that they are the same setup. Do you carry any proper weight from time to time?
Snapped spring on KW1
Got the bill today to replace the second failed spring. It seems that KW are only willing to replace the snapped spring (and not the rear pair) following the failure. I told @BognorMotors to replace both rear springs following the failure, even if I had to pay the extra. I can't grumble to...www.t6forum.com
I‘ve done 3k miles with them down like this although only recently removed the adjusters and fitted the Powerflex deletes to bring the back down further. The only weight in the back is the Kombi bench and my storage pod that holds the Ecoflow Delta Mini. Mostly just me in the van - although I am fat I wouldn’t say I was ‘proper weight’
