what do you mean "rotate the lower body"?

 

the lower section you can rotate it (clockwise) to make the body shorter... iono how to better explain that lol. hopefully someone can chime in

 

just wondering, are you running spc upper control arms? because i am and they sit about an inch higher than stock with my front bc racing coils fully slammed? and at that height it was not even close to tucking till i added the exact rca.

 

I have the BC coils, it can only go so low as you can tell when you adjusted it lower. The other solution is to adjust the springs to come lower, but you will lose suspension travel and void the warrenty.

 

Exactly thats why i'm thinking it has to be my upper control arms. Sorry to thread jack.

 

You can void the warranty if you adjust the springs perch?

 

If you lower the perch, it would allow a higher possibility to bottom out. Also, as I recalled reading my BC manual, I'm not allowed to adjust it for height purposes.

 

no, it would be the RCA or the Coilovers that would adjust height. The upper control arms has not moved position (it's a constant variable).

 

How could it be the coilover or rca? When i compared the height of the coilover to the height of the spring/strut combo i was running, the coilover was shorter so if i install it, it should bring the whole uca, lca assembly up therfore lowering the car right?

 

You're allowed to do whatever you want with the coils. You can adjust both the lower strut height mount or even the spring perch. All the spring perch is doing is either pre-loading the spring or not. If you move the spring perch down, your travel will be reduced by the amount from finger tight pre-load to the point you move it down (say, example 1"), then your internal strut travel will be reduced by 1 inch. It needs to reduce by the amount you lowered the perch because the internal valving needs to compensate for the lowered overall spring. Unless if you only have 1" of travel to begin with, lowering the spring perch will NOT harm anything. Bump stops are there in the first place to prevent internal valving "bottoming" out, so no harm will be done to the suspension components themselves. However, yes, if you do ride on the bumpstops constantly, it will be horribly bouncy and annoying.

You aren't corner balancing the car for "race" purposes, so it's perfectly fine to have no pre-load on the springs.

So, with that all said, go lower the spring perch down and see how much you can go lower. The coilovers should have more than enough compression and travel to compensate for the spring to be lowered all the way, anyway.
