I am planning to install an E30 M3 5 lug setup on my 1989 325 convertible.
Currently, H&R sport springs (for E30 325 convertible) is installed on the car. I purchased an E30 M3 5 lug setup that I am going to install on the car.
Can I use the same sport springs or I have to buy an e30 M3 version of H&R sport springs? I know H&R sport springs are different between the two car but I don't know why and how diffrenet.
I also want to know if there is anything special I need to watch out for in this 5 lug install or it is pretty straight forward?
Thanking you in advance for your help.
