*In practice* coilover/spring pairs should be set up so that no preload is neccessary (so says my OPINION for a street car, before anyone tries to argue). All other possible issues aside (wrong parts, incorrect installation, etc..), if you absolutely must go lower, you can preload the rear the same distance you want to go lower, then bring the bottom perches up to that level.

*Update: After looking over your picture further, this may not even be an option for you, depending on how far into the bottom sleve the damper is. If there's still space left, you could remove the height adjustment perch entirely and gain 3-4 more threads.

 

What I meant is did he preload the front/rear suspension bushings. I did not mean the Flex's. Also, TEIN has the preload set to zero accoring to their measurements.

Then again did the OP follow the TEIN measurements in the beginning?

 

Everything came in one piece I didn't do anything to it -_- , I also have another set of coilover that is doing the same thing, so im guessing something wrong with my car. I'll probably try to install these coilover on my friends car and see how it goes.

 

compare your stock strut and spring height against the CO's.

 

When I put mine on I adjusted them to the intial settings they call for in the instructions, dropped it on the ground and took off, no problems.

 

Did you give time for your springs to settle?

 

Here's what my Mono Flexes looked just out the box. Installed them as is and had about 1.5 finger gap before they settled to about a 1 finger.

 

I just had a thought...did you adjust the bottom perch or the upper perch...Doesn't the upper perch adjust spring preload, whereas the lower perch actually deals with height adjustment.

 

I am no suspension guru...but it appears as thbough you have a good bit of adjustment left from your picture. You must not be adjusting correctly.

 

the rear is all the way down, thats the only only im worried about, the front I can slam easily
