Ok so here is a picture of my adjustable lowering springs:


Now whenever i hit a big bump or dip going too fast (on accident) there is a loud BANG! And i finally figured out what it is. If you hit a big enough bump or a dip your spring will compress as far as it can go, and my shock will compress -and if they compress enough the treaded tube will nail the top mounting plate:


There has to be something i can do to make it so that the rim of the threaded tube will never hit the top. I was thinking either getting a rubber tube that sits on top of the threaded tube and goes around my shock -or maybe cutting the threaded tube shorter:


Any suggestions?

So, you have something like skunk2 coilovers on stock shocks that are bottoming out basically? If so, your cutting or rubber method will stop the noise but not the real problem. You would need higher valved struts. KONIS.

Yeah i totally agree. I do need to get new struts, but this is really driving me crazy so im kinda looking for a good solution right now, before i get new struts.

You would have to take off those sleeves to trim them and you would lose your alignment. The rubber method might be a good temp fix but I've never tried something like that. Good luck man.

Yeah i'll post some pics if i pull it off.

if your idea with the rubber preventing from bottoming out works out, you might have create a useful tool for those lowering methods goodluck though and hope u find a solution for your coilovers

 

yeahy get some koni yellows should fix the problem... i was gonna go with my ground control coilovers and stock shocks, but was told too many problems, so i said nope and spent the extra money and got the TEIN setup, shocks and coilovers, so much better in the long run

I really want to go with konis, but i cant really spend the $500 right now. I'll keep you guys posted if i do this rubber thing. -I think i can make it work, but we'll see.

You have a couple of options...

1. get stronger springs (the higher rates will stop the car from bottoming out, but give a rougher ride).

2. Raise the car up a bit, to give the suspension more travel.

3. Cut the sleeve

Thats pretty much it. Even with Konis the car will still bottom out because of the Ride height and spring rate... Bump stops will lessen the blow but you'll still bottom out.

Yeah i think that the best solution is to cut the sleeve short. You can see in the picture, the sleeve is like 4-4.5" tall. And unless i plan on doing some rally-cross i think i can cut those a hell of a lot shorter.
