installing springs and upper control arms help

[pavell]

guys i am installing hotchkis front lowering springs. i have the old stock springs out right now and the lower control arm is free from the balljoint.

should i compress the new hotchkis spring and attatch it up and install the Speedtech upper arm with the jack under the lower control arm? ...OR should I remove the brake assembly and stock upper control arm from the upper balljoint and install the upper arm with the spring out?

what would be the easiest way to go about this?

Thanks
