Ok, in answer to your earlier question about suspension for under 200 euros, have a read of

It's a pretty long thread, but the guts are: Belgian company sells budget adjustable coilovers that lots of people on SCN have and like, typically cost around 160ukp or there abouts including shipping etc to the UK. There's an email address in one of the early posts by Suj, you need to write to the guy (his name's Edwin), tell him Suj on SCN sent you and ask him for his unadvertised special price to you. I've written to him in summer when I was trying to decide what to fit to mine, and he got back to me very quickly. Please remember he's at work when recieving and sending emails, so if you write him on Friday, you may not get a reply til Monday.
Coilovers obviously give you on-car adjustability, so you can pick your drop.
Lowering springs with (old) standard shocks: your mileage may vary. You might be very happy, you might not. Your standard dampers may not last very long due to loading depending what state they're in. All you're going to need to fit springs are
- a lifting method (say a trolley jack)
- a support method (say axle stands)
- some sockets and spanners to get the struts out
- POSSIBLY a special socket to undo the nut underneath the top-mount (think standard set up has this; mine was Koni already)
- an impact wrench with 22mm socket will make getting the top nut undone about a million percent easier/possible
- a r
egular set of spring compressors (don't need to be anything like as long as they would for a pug 205)
Do bear in mind that when you refit the struts your geometry
WILL BE OUT OF ADJUSTMENT and you will need to take your car to somewhere that can do proper 4 wheel laser alignment to sort it out. I use my local independant VAG specialist and he charges 40ukp including all adjustments. If you don't do this your handling will never be quite right, you may have problems on ice/wet roads and you may wear your tyres out far more quickly. If you really want to save money here then make sure you carefully mark the position of the strut:hub carrier before you start undoing bolts.
It'll still be WRONG with the shorter travel, but less than it might have been.
You should really replace the top-mount bearing and the bolts holding the strut to the hub carrier. Thread-lock on the old bolts is the absolute MINIMUM you should be considering.
I'd forget about the wheel-spacers for now. You've got your hands full making this lot work already, and unless you simply want them for image, you may find you don't need them.
Cheap spring and strut suspension is going to outperform similarly priced coilovers every day if it's fast road driving you're looking for. Budget coilovers are the cheapest sensible option if you want a low car for the look.
If it's performance you're after and you don't really care about the look, then don't underestimate the impact that simply renewing your standard shocks (keep the original springs) and as many bushes as you can afford with standard items. Honestly. It's a breathtaking improvement, and if done properly you will have a factory-tight car again instead of an 11-year plus one. Assuming your springs are OK.
I justified buying my replacement Koni kit as the existing Koni's on the car were shot, and the standard springs are the expensive part of the OE kit. It was going to cost almost as much to put my car back to standard as to fit the Koni's which preserved the 25mm drop on my Cupra - they'd give the 60-40 drop you're looking for on your car I think, but they cost nearly double the cheap coilovers above. I bet they handle better though.
Sorry to be a downer; I totally understand if money is tight you can't have everything nice. You say you don't mind waiting for a saving; sometimes it might be worth waiting to do something properly? If you screw up your engine or exhaust or bodywork trying to cut corners it's note that big a deal, just costs money. If you screw up suspension or brakes trying to cut corners you can seriously kill yourself and others.
If you really want to mod your suspension on your budget, email Edwin... it'll be cheaper and safer and probably work better than ebay finds.
