BC Racing extreme drop Coilover Issue

[ChandlerSwyng]

The ST coilovers seem nice just not sure if they will provide the kind of low I want

A clunk from the front is most likely the sway bar contacting the lower control arm. That is the reason they come with adjustable end links so that you can place the sway bar in the correct location with a lowered ride height. I went with BCs because a South Eastern FR-S was breaking NASA TTD track records using them, so they were good enough for me.

Can you clarify a bit on this for me? I'm having a bit of trouble with my sway bar end links contacting the front LCA.

I called the guys at Fortune, and they advised me to LENGTHEN the adjustable end links in order to push the sway bar down, and away from the control arm. As of recent, I've been reading that people have actually been shortening them instead when running lower ride height.

As it sits, my end links are maxed out in length and I'm still getting a bit of contact. Looking at it today, it seems that if the opposite were true, I'd actually need to have the sway bar ABOVE the LCA rather than below it to avoid contact.

I'm sorry if this sounds ultra noob, but it would help me a ton.

EDIT - I'm not in the ultra slammed club either, I still have plenty of room to go down -

The correct way to set your sway bar end link lengths is to get the car on a drive on lift. This isn't always possible, but you could jack the car up and place it on some ramps or cinder blocks or something to get it high enough in the air under it's own weight to be able to get underneath it to adjust the sway bar end links. Ideally you want your weight in the driver seat as well, so if you have a buddy, have him sit in the car while you do this. Then you want the end of the sway bar to be as near parallel to the ground as possible so place it there and then lengthen/shorten each of the sway bar end links till the bar sits in that position without any preload from the end links. Setting the end link length this way you can see how close it ends up being to the lower control arm at ride height with the car under it's own weight. I would make sure it is at least a finger width's gap away from the lower control arm.

Thanks so much man, this helps a lot. So, in general, the end of the sway bar sits ABOVE the control arm, not below it?

Definitely.

I recently installed mine as well just a week ago! I had a small clunk up front, ended up removing the adjustment knobs on top and tightened down what I believe is the pilo nut on top? Correct me if I'm wrong.. (The nut under the adjustment knob). This tightened up the entire assembly Im told. I had a knowledgeable friend doing the majority of the work so I may be getting my terms mixed up! Over all very solid setup from there, not a single sound after we did this. Seems they all come abit loose from the factory since he had the same issue.
