Have you checked your fuses in case you blew one??? and your ariel shouldn't be going up and down as soon as you turn off your HU it sounds like you had the antenna wire connected to the acc wire and not the dedicated power wire for the antenna
Yeah thats all fine, as said before just cut the power cable to keep it nice and neat and run your rca's on the passengers side to stop any interference problems you can get from having them next to power wires.
Nice car, i love the wheels generally im not a fan of wheels of that style, but they look really good on your car. Also good choice with getting the S1 i prefer them over the 2's
Ohhh if its for an id inspection im sure you will get through when i took my line to get checked they were pretty lenient they only really cared about ride height and window tinting
best place ive found to get silicon hosing is from Outlaws speed shop near the market, there you can buy it by the meter but from autobahn when i tried to get it from there they sold in in bulk packs of like 10m for ridiculous prices!
What brand are they?? i tried looking for somewhere in SA that could rebuild mine but didn't have any luck....the only 2 places i found that do coilover rebuilds were both in qld if you have Teins you can send them to Fulcrum if there another brand Shock Reco can do them
But just being bushes as Nightcrawler said im sure a place like Pedders could do it
