I am looking at buying the h&r sport springs to lower my car, but i noticed on the description they only have one for a non sport suspension.

I assume i have a sport suspension because it is a 2015 435i msport (convertible).

My question is can i put the non sport h&r springs on my f33 m sport or will that cause problems?

Or will i have to find a brand that makes a lowering spring for the sport suspension?

they work for non M and also M sport. I have a 2014 335i Msport and have H&R supersport.

yeah but they make springs for 335 with sport suspension they only make springs for 435 with out sport suspension
do you have the non sport suspension springs on your m sport?

The H&R springs are shorter, firmer, and less compressible than the stock springs (regardless of sport or non sport stock springs. H&R Sport springs will drop the car by approximately 4cm (1.6inch) front, and 3cm on rear (1.2inch). Super sport will drop by 4.5cm front and 3.5cm rear.
Plenty of people are putting H&R springs on their car. You can google image it up if you wanna know what it looks like.
