I need to get a small amount of lift (support) in the rear end when towing. My Treg already has upgraded springs, but still squats slightly in the rear when towing a van. This is causing some scrubbing on the inside of the rear tyres. I've just done 25,000 kms around Oz and I needed to have the tyres rotated on the rims due to scrubbing. There has been a lot written about the prohibitive cost of upgrading steel springs to air springs.
My question is: Is there any reason the standard steel springs cannot be replaced with air springs and just connecting the air line to a valve and leaving all the electronic wizardry disconnected?
I could then pump up the springs for towing and release pressure when the van comes off.
Any advice please.
Cheers
