I suppose 4 lowered springs and some new shocks, cant really be called a 'kit' more of an 'upgrade'

whereas the coilovers are just that.... a kit

I also had these when I had just the lowered and unrated springs and wot goopy says about they can handle a bit of lowering is spot on,

What about a shorter damper insert in a standard strut when you lower the car ? to off set the new shorter spring and keep the travel ?

lets work out some costs,

Set of springs £200 ish (standard fit & size) £160 ish for 2.5" ID and £120 ish for 2.25" (but will need adjustable platfoms)

Set of dampers say £150 each adjustable (KONI's for example) not sure on Tokico prices,

Coilover adjustable conversion parts. threaded tubes, nuts and new bottom weld on mount, £200

Adjustable top mounts (weld in or bolt) £200

Solid Pillow Mounts ( the ones you can index round for camber) £200

RCA's ( offset or not) £150 or £90

Then you've got adjustable front control rods, rear adjustable arms etc etc ...

If you just want to lower a car a bit and have decent dampers you are looking at around £800 and I think the BC's retail about £850 of course this is without fitting and assuming you can do the work yourself,

If you add up all the adjustable parts and coil overs the BC's seem an even better deal

Because your springs are stiffer ?

The idea is not to go for a stiffer ride when driving a lowered car.

Thanks AM.....useful data but still not near an off-the-shelf kit - buy this here, buy that there and then add it up - the BC etc is a 'bargain'.....but stiff !

What sort of kit do we think we need then ? by that I mean all made here in Europe ?

2 kit options ?

1st for mild weekend street\track day I.e lower stiffer springs with adjustable dampers

2nd more of a higher spec coilover conversion with shorter struts , weld on like the BC kit maybe and with adjustable top camber ?

I can make most of the bits apart from springs and I also have a contact for dampers,

But it all comes down to cost , I would have to do the maths but could I do a kit that is cheaper then the BC....

2nd - I don't think so - plenty of that type of choice already out there and a minority (compared) market.

1st would be my choice to sell :

a BC-lookalike kit, lower, progressive springs (as per Eibachs), dampers only 'adjustable' via the coilovers.

Keep the costs down and maybe even sell it without the dampers and let people buy their own (with reccomendations of course).

My experience with lowering springs is you always get a front high condition. I've yet to see any that lower the front enough when compared to the back. As Sean has said, you also compromise the available suspension travel unless you section the strut. You have no adjustability to set the stance exactly how you like. I've gone this route before and wouldn't do it again.

Sectioned struts and adjustable spring height/dampers are not cost effective when compared to BC's so for a basic cost effective kit that suits most people, BC is the way to go IMO.

I'll try and find the name of the other company I spoke to at Autosport who supply rebranded BC's at around £700. If you look on ebay US you will find a number of 240z kit in this price range.

These are lowering springs - still too high at the front?

No Jon but the low-profile tyres are awful.

John - I'd also like to know please the contact for the softer springs for the BC kit you mentioned.

One of the reasons I'm asking is that some have fitted that BC kit and it's 50/50 feedback on the overall satisfaction for road driving. One guy has changed to BCs' softess spring rates and still claims on the local roads its a real handful......so I'm trying to find reasonable altenatives or good solutions not just for him but anticpating others asking the same questions.

No-one's mentioned yet but being able to adjust the height/spring stiffness will also affect the corner balancing and therefore directly the cars handling.

You can only do this with coilovers.

I think the set up I have is a good compromise,wot ever you go for you will know it when you hit a pot hole but apart from that can't fault it

Sean do you know what size the BC springs are 2.5" or 2.25" ID ?

You would of thought they'd of used a standard available size when designing them, which means there is a massive selection of length and rate available.

If you fit lowering springs you could fit a shorter damper in the Strut so it has a full range of travel again, there are shorter dampers about that work,


I have added up and costed everything now for my new Z and it would be cheaper for me to buy the BC kit or the re-branded set John mentioned above, and thats with me being able to make most of the parts my self
