My Golf is fitted with FK Highsport Coilovers. They were on the car when I bought it and it's very low....a little too low. I'm fitting some new wheels which will scrub the arches at it's current height. I want to raise the car so the wheels will sit nicely. There's two rings below the spring. I'm assuming one is for height adjustment and one acts as a locking nut? I have a C spanner. I've never adjusted coilovers EVER. Does the ring need to go up the thread, or down it to raise the suspension? I know I sound like a Knob but I'd rather have an idea of what I'm doing. I'll be cleaning the thread up and lamping on the WD40. I'll be having a crack tomorrow as it's like a tropical storm here in the west midlands today

You need 2 c-spanners, 1 to hold the locking ring and 1 to undo the ring that it's locking. You need to screw the ring up the strut to raise the spring height.

I've only ever owned one C spanner, use a drift and a hammer to bash the lower locking collar round til it's free, then wind the spring platform up by the amount you want to raise the suspension (it's 1:1 ratio) then tap the locking ring to tighten. Get some proper penetrating fluid - WD40 is no good really. Wire brush all round the threads then hammer loads of penetrating fluid on, repeat after an hour or so then leave them overnight at least. Make sure you can get all 4 dampers moving a turn or two before adjusting any of them much - if the coilovers have been on the car for more than a few months and they weren't greased up, there's a real chance at least one of them will be seized. With them being FK you have a better chance of them moving than ebay cheapies though - A bit of heat does help shift a stubborn collar but don't go wild - heat it up all the way round and it should expand enough to become free. I needed a blowtorch on two of the four JOM coilovers on my MK3, and they were only 4 months old, but the guy who fitted them left them dry. To make your life easier in the future, once you're happy with the ride height grease the absolute knackers out of the threads - some people use copper grease, I've had good results with this: www.ebay.co.uk/itm/Multi-Purpose-White-Spray-Grease-400ml-Penetrates-Lubricates-Protects-/300848026569?pt=UK_Vehicle_Oils_Lubricants_Fluids&hash=item460bf093c9Two cans will do a nice thick coat on all 4 corners.

They've been on quite a while by the look of them....and they're dry. I'm in for a bit of fun tomorrow I think! Thanks for the advice. Hopefully, it should be straightforward (not gonna hold my breath though) I've got a blowtorch and some penetrating fluid.

Maybe a stupid question, but my coilovers only have one ring. Why?

They might have a grub screw to lock them instead of a collar.

The advice was spot-on as usual! The first three needed a bit of penetrant and a tap with a drift and lump hammer. The last one was an absolute nightmare. Luckily, the Thiefbay C-spanner had a fitting for a ratchet/breaker bar so had to get the breaker bar on it. I ended up raising it 30mm all round. Hard work though!
