I also got some gTechniq C4 for giving the trim a permanent dressing.
You need to be careful, can easily over do it and also make it patchy.Never used gTechniq before but I used a heat-gun on the plastics of the the passat and it was absolutely amazing the difference it made.
Don't use the heatgun. I sprayed those plastics with Simoniz satin paint a few years back and not sure what a heatgun would do to the paint. Probably cause a right mess.
I've lowering springs in the shed for a mk3 actually. Eibachs too but fronts had a coil removed and was a bit low on that wee car IMO. Ended up getting replacement front springs from Weeloaney but can't mind what brand they are. Think they also needed the larger top mount plates which I bought but never used lol.
Must remember that coolant pipe.
