I'm running GPM alu shocks towers and Kyosho original oil shocks (with black springs). I want to lower the ride height quite a bit as it's currently about 22mm front and back with normal wheels and tyres on, fully loaded with battery etc. Is it as simple as get softer springs or are there any other tricks I can use?

Also, my front shocks seem to bottom out before the body does with the new alu shock towers regardless of the hole position. Is that normal?

I've got all the GPM alu arms front upper and lower and rear installed.
