isc n1 coilovers or bilstein b6

i have 2015 m4, non edc.

currently have h&r super sport lowering springs on stock struts. the front struts are blown now, obviously.

i was searching for coilovers and found the isc n1 coilover kit. bimmerworld sells them and are pretty affordable ($1500 cad)

or just get the bilstein b6 hd struts/shocks from and rear and use my springs. i know they are not really made for lowering springs but i heard that they do work and are a good upgrade from oem. ($1200 cad)

i like the coilovers because of the camber plates, adjustable, price, fully re-buildable. usa made.

the b6 strut/h&r super spring, will be set it and forget it.

there is much for track riding here in edmonton canada. but i always liked the feel of coilovers, just feels planted and rigid.

My suggestion would be to just go with the Bilstein B6's. They typically valved perfectly for a very compliant street ride, but sporty enough to handle some track days. Major improvement over stock.

While admitidly i cant speak about this specific application, I've run Bilstein sport / B6 struts with lowering springs on my last 2 cars (VW R32, B8 audi S4) and they have been amazing setups. With coilovers, more often than not, you get what you pay for.

I had such good luck with the bilsteins in the past that I went with their B16 damptronic coilover kit, since I have EDC.

The b6 isnít available until end of the month and the isc coilover is 6-8 weeks back order, so probably go with the Bilstein.

Best mod I have done in 3 years of ownership is B6D + Eibach springs. You won't be disappointed.

If you fit B6's with OE springs you ride height will be higher though by 10mm. Go lowering springs.
