Cabrio mit E30M3 5 Lug and M30

[BDK]

So I am getting ready to purchase springs and shocks/struts for my cabrio project....

After the suspension and brakes are done I am dropping in an M30,
so my questions are:
to be able to balance out the car once the M30 is in it,
would it be better to buy Koni adjustables all the way around

or will billies sports work just as well?

Should I go with H&R sports or racing to help carry the extra weight of the M30?

I am asking because none of the springs/shocks/struts are designed for the extra weight of the M30, the rear springs will have to be cabrio specific right?

All e30 run the same strut/shocks right with the exception of the IX?

I jsut want to do this once and want to make sure that I am buying the right set up the first time...

Thanks for any input...

What are you going to use the car for?

The extra weight doesn't really matter. Unless you are building the car strictly for track purposes you probably wont even notice.

a Daily Driver...
but we have good roads here so I am looking for a good set up but not bone jarring...
