The rear spring that came with my coils are just too stiff in my opinion 7kg/mm 392ib/ in

My question is can i run the stock rear springs? They are linear and ive seen people use ways to lower there cars with them but not with a coilover setup im thinking about trying it atleast till I can find me ether bc racing springs that work or if maxspeedingrods has a different spring they can sell me directly then im going with that for sure im assuming from what I read that the rear stocks are 6kg/mm or something along the lines of 6k not sure if ive got that right but if itll work ill stick with the stock springs and just buy new ones they were comfortable. Lmk what you think and or person experience. If someone wants to pull some vs and say I should have bought more quality coils to each there own the front is perfect just the rear that I can fix with springs being changed.

 

Accidents happen remove all preload from the maxspeedingrod rear spring remove the little metal plate and locking collar and just tighten down the collar that holds the spring and it is a very comfortable ride right after that !!!
