Here's my nube question : Spring rates are 6K and 8K. Are these additional to my stock springs ? Are the stock springs taken off as well as shocks when going with coilovers ? I looked at a coilover DIY instructional and was still unsure ? What are the stock spring rates of my 2006 Z4MR ? I've just started AX ( 2 completed and love it ) and I plan on moving up to HPDE in the near future ( Sebring )
if you install coilover, you dont use stock springs anymore. they are too wide for coilovers.
