Tein Basis Z Coilover questions?!?

So last weekend I was under the car having a look at the under side when I noticed the springs on my car where looking rather worse for where and quite rusty. I had been toying with the idea of changing the springs anyway to coilovers as when I got the car the previous owner had lowered it with Swift springs by 35/40mm. Now, as much as I love the look and the stability these springs give the car in the corners it is very harsh and some what crashy when just driving along. I often find myself trying to dodge around alot of pot holes over here in the UK and have on many occasion had the rear wheels bash up into the wheel arches - Not a pleasant experience!
Having been looking around at the various options I do like idea of the Basis Z's as it will give me the flexibility of being able to adjust the ride height (fairly) easily, but without them being over complicated with dampening, camber, etc. Having looked into the spring rates could someone tell me if they think it will make the car ride even firmer due to (in some cases) the spring rates being higher. See Below:

Stock Springs Front: 2.2kg / Stock Springs Rear: 3.4kg
Swift Springs Front: 2.6 kg / Swift Springs Rear: 4.2kg (currently fitted)
Tein Basis Coilovers Front: 3kg / Rear: 4kg

Also, when changing over to coilovers from a car that is already lowered are there likely to be any other parts that are required to be replaced? I know these particular coilovers re-use the existing top mounts which I understand was done on purpose to help reduce the manufacturing cost.

As always, any information or advice would be greatly appreciated.

So I've taken the plunge and ordered the Tein Basis Coilovers. They should be with me in the next week or so and have got a local suspension specialist fitting them Early November. Looking forward to seeing what (if any) improvements these will make to the car ride. Will keep people posted and hopefully get some before and after pics.

So today is the day and the Coilovers are being fitted. I've managed to get a few pics before the install and will post some up when the install is complete. The shop have asked if they could use my car as a case study for their website and will taking some install pics for it/me. Hopefully once they have done a write up I can post a link up on here in case anyone is interested.

For me, they are worth the money. The Swift springs that the previous owner had fitted I felt were too harsh / stiff for the UK roads and lowered the car too much (40mm). I would often get the rear tyres banging into the liners in the arches and it was very off putting and was scuffing the tyres. At the time I was on a budget and went for the Teins as reading up on them they allowed for a slightly more forgiving ride compared to the swift springs and it also allowed me to adjust the height of the car. In the end the car was set to Teins recommendations. The ride quality going over bumps has improved compared to the Swift springs, but it is still firm compared to a stock Cr-z. I also have slightly more roll in the corners too compared to the Swift springs but this is due to the shop who fitted them not doing such an aggressive Geo set up. I am looking into sourcing a Spoon Front Swat bar at some point so will look into getting the Geo set up altered once the FSB is in. Hope this helps.

No worries. I went for the Tein Basis Z ones at the time as I was on a budget and I felt the springs needed to be done promptly after i saw the state of them. I think i paid around £450 inc Vat + delivery and around £265 for the install and Geo set up.
As for going for the next ones up that would be down to your decision. I guess its a case of working out if the extra money you spend on these and the potential extras that come with the next step coilovers will be of benefit to you and if it will suite your plans for what you would like to do with the car.
I've had mine in now for around 8 months and not had any issue with them. They do seem to handle the delightful bumpy uneven roads here in the Uk well. Where about's are you based?
