Great one John, but wouldnt you want to use 8?

Seriously, there are a lot of us that have coilovers on our Z's and it is the correct way to do this. I would use the "Search" function on the website to see what people have done....

Then when you are completely confused call John Coffey at Beta and he will tell you how to do it the right way based on how you are going to use the car.

ya J mort, it looks like you actually put use to your Z, I love the Track shots, Ive seen a set of used coilovers, but manytimes when buying use anything, many problems arise, I use many susp mods, but I am a nissan 240 owner, so ofcouse the main major modification I ever did was the suspension, I would often see coilover set ups but that do not have toe ajustment, similar to the stock 3 bolt top. I also see a product, i beleve from techno toy t, a camber plate, has anyone ever use this, I know it seems like a little bit of work cutting into the strut top and welding this is,

Its just tobad i dont have any connections in japan yet, becouse there are many coilover set ups for the S30 chassis, that is equal to modern bound, rebound high spring rate coilovers, which do wonders... :classic:

^I dont doubt you, there are many top notch companies who make coilovers for the S30, but becouse of the popularity with more of a restoration side, rather than a motorsport side in the States, the products never made it here, if the coilovers preform like anyother well made japanese coilover they will improve the car 100%

I don't know where you're getting your info R&D, but you're extremely wrong. There's plenty of coilover suppliers right here in the US. There's quite a few camber plate suppliers, in fact there's even several choices for tubular control arms, big brakes, flares, pretty much anything you want. Try google sometime. Or search here or one of the other Z boards.

My 2 cents. I think if you want to lower your car, then this is how it ideally would be done. This would drop your car as low as you want it and bearly effect anything. It would be a rather difficult process though. You need to do what is called a spindle drop. In stead of reducing the spring height to move the hubs up, why not just move the hubs up? This would maintain all of your factory suspension geometry (no alignment or bumpsteer problems), it would also maintain the full factory suspension travel (allow a softer spring for those who desire the smooth ride). The problem is that this would be difficult, on a Z at least. In the rear you need to somehow loosen the tube that holds the strut insert from the hub portion and then raise that collar up the strut tube. Then you need to lower the lowest section of the hub where it connects to the suspension arm. In the end the strut should be the same length but the hub should be higher on the strut. This same technique works on the front. I know the Porsche 911/930 front struts spindle can be raised simply by drilling out a spot weld, raising the spindle and rewelding it to the strut. I havn't looked into doing this on my Z, but it is definatly possible. The car would still benifit from coilovers, they would allow a wider tire and adjusibility.
