Rather annoyingly, I’ve just realised I never measured the drop from the top of the wheelarch to the floor before I started all this, so I can only really say “a bit lower”. 
The front springs are quoted as two inches lower than standard, whilst the single leaf rears had almost three inches less unsprung curvature and have currently got one and a half inch blocks on too. Against the tired old multi-leafs, my guesstimates is that the back’s about two inches lower.
Intrigued though, so I’ve just been out with the tape measure and it’s near enough 22 and a half inches on each corner, from the top of the wheelarch to the floor.
EDIT 01/01/08 :
Dave : Curvature doesn’t really come into it. The singles are a fair bit stronger so don’t bend as much under pressure. The multis are quite soft at first, so will drop to the same level as the singles with little pressure. They firm up as more weight is put on and more leaves come into work. 
Rude Dog : Just need a good set of laser or 2.8 alloys now.
Any thoughts on the wheels?
me : I have to admit that I’m not the biggest fan of the ubiquitous Laser 4-spokes, though they do look better with the recessed parts of each spoke painted black to create the “illusion” of an 8-spoke.
I’ve never liked “pepperpots” from the very first time I saw them many, many moons ago… personal preference, not an opinion on other people’s wheels.
Don’t really like the 7-spokes with the little cutouts towards the rim either, as, to my eye, they just look like a plastic wheeltrims.
Genuine Slotmags are nice, but most that are offered up for sale nowadays seem to be period imitations that were slightly different to avoid accusations of being a direct copy – but they lose the sculptured lines and proportions that “just seem right” in the process 
Then you have to try and find a set of wheel centres and nuts and the price sky-rockets 
Revolution 4-spokes all seem to have the spokes and centres blacked out, which makes the middle of the wheel seem to disappear on all but the sunniest of days … and if you get wheels to improve the appearance, why get ones you can’t see? 
Weller 8-spokes are nice in chrome, but Dave’s got there first. The white 8-spokes should only be attached to a Series Land Rover in my opinion 
There was a set of SS Cragars that I had my eye on a while back, but they ended up going for truly silly money, so I consoled myself by saying they were “too much chrome for the car” 
I’ve got some old issues of Custom Car from the late 70s/early 80s and some of the wheels in there are very tasty, but were probably only produced in such low numbers that finding a set these days would be hard
Time will tell I guess 
Reading back this sounds like I’m some kind of a wheel obsessive, but these are just occasional random thoughts – honest
Dave : There is nothing wrong with the wheels you have in my opinion Stu.
If you are desperate to change them, how about getting them banded for a wider look? All the rage apparently, and certainly a period look to them. 
One thing with wider wheels on the back of a Capri is that it means less room for the back box section of the exhaust.
I can pretty much guarantee you will encounter that familiar sound of exhaust v spring, or exhaust v rear valance.
Rude Dog : Daves sorta right in a way, the wheels you actually have are fine, they just look lost under thos arches. My first Capri had the same flower petal style steels with the chrome band and looked much better after i’d spaced em out a bit
I also managed to get mine fitted with 185’s which helped the look but did little for body roll
me : Funny thing is – for all my pontificating, I don’t think there’s anything wrong with the current wheels either I can happily think about changing wheels all day, as just thinking doesn’t cost ‘owt (Thanks Matt )
Part of the plan for this year is to strip ’em back and repaint them, mainly as once you get closer than ten feet they really do look quite shabby. Thankfully, they seem to come out alright in most photos, no doubt enhanced by the “chrome effect” trim rings, which also manage to make them look quite dished too
What they need as much as a repaint though is new rubber, as the current cheapy “Stunner”s are of unknown vintage(s) and the spare looks even ropier and cheaper. They’re currently 165/80/13s and I’d like to move up to 185s for that extra contact area (as much as the appearance/stance). If I’m buying new rubber for all five corners, though, I don’t want to be constrained because of the wheels. 
At the other end of the scale, I don’t need or want big fat wodges of rubber either, as they tend to come with big fat price tags – which defeats the pocket money ideals of the project anyway.
I’d not really thought about banding – I know it can still be done, but haven’t got a clue about cost. Staying with a 13″ rim is paramount however 
I’m basically just keeping an eye out for what’s out there. I know what sort of wheel I’d get given a cheap enough “cost to change”, but it’s not the most important thing to be done. It’s one of those things where I know what I like and I know what I don’t, so I just wait until what I like becomes available at a price I’m happy with.
sven : You must have a lot more time than me stu,Stick with steels a lot less hassle saying that Ive got 280’s on mine.
Plus have to say super flex are a lot dearer but a lot better fit as you have now found out
