DIY coilovers: Learn me

Running out of compression travel on the damper is a very common problem on lowered cars, especially when you consider you have to leave room for a bumpstop ON the strut shaft on a lot of cars. Being able to adjust the damper itself farther down into the strut yoke helps address this problem, even if the damper itself is shorter overall.

Except, that is not what is being adjusted... it's always the lower spring seat.

Knurled, did you not see the photo posted by GameboyRMH?

Bringing the thread back on track:

Is there a removable clamp on coilover sleeve seat?

Nope, not for sleeved coilover money. The closest you can do is to lower the car with raised upper strut mounts/camber plates so that you don't have to lower the spring seat too much.

Build a bare strut tube much like mine, but thread it all the way down.

Get some tubing 1/4in thick and slightly smaller in ID than the tube thread minor diameter, weld brackets to larger tube, take to machinist to thread the ID.

Tube thread minor diameter?

In reply to EvanB:

Thanks!

Sorry to bring this back from the dead but I came across something called a shaft collar and was wondering if these could be used as perches for the threaded sleeves?

In reply to Fitzauto:

I know what you're talking about.... It would rely on squeezing the strut OD for grip to not slide downwards.

I'd avoid it personally, but if you must, remove all paint where it is to be clamped, and the shaft collar ID, and coat with red loctite to make it semi-permanant. And loctite the clamping bolt too.

That is IMO best chance of making it work without spring perch dropping down without doing it properly.

Edit: and use a split style, not a set-screw style shaft collar.

In reply to flatlander937:

Im guessing it probably would not go well if you hit a large bump. It was just a thought. Ill probably end up making a sleve perch that sits on the shock for the rears.

Now that you've bumped this thread, you might want to check out Tein Flex Z coilovers. Great quality for the money, including sensible damping which is where most of the cheapo coilovers fall flat.

Which company could supply the threaded bodies, I'll supply the lower mount. 

Thanks

I know BC Racing will sell you individual parts if you want to piece something together.

In reply to obsolete :

But could I use bilstien dampiners and diy 3 way coilovers with reservoir? 

With the weld on threaded sleeves I don't think you have the ability to preset some preload into the spring, but I also don't know what advantage there is in preloading anyway ..

In reply to dannyp84 :

Oh I'm looking to build a 3way inverted strut if one isn't available by itself. No I am not reinventing the wheel or being cheap.  I'll use high end valving.
