Question Bilstein B4s Vs. Sachs Struts

So I recently bought Bilstein B4 struts for my long over due busted struts. I had previously bought rear Sach shocks because they were shot as well. I forgot i had Sachs in the rear until after i bought the Bilstein's.

My question is if its alright to run 2 different pairs of suspension? Because i did slight research again on the difference and the answers were pretty mixed; some said they're practically the same, some say Sachs are more comfortable, and others say the B4s are slightly harder. I chose rear Sachs because i wanted more comfort than "sportiness" and i think they were cheaper compared to B4s back then.

Now both the Bilstein's and the Sachs are practically the same price give or take like $10. I don't mind exchanging the B4s if its not recommended.

Totally fine. If you were talking firmer shocks it could make a difference, but those two are practically the same.

I run Bilstein B4 front and rear and I find they are stiffer than Sachs.

Don't forget air pressure. If you're riding around at >40 psi on either brand, it's going to be stiff ride. 18 or 19 inch wheel also aren't the best choice if comfort is priority.

The B4s are very close to OE. If this were my car, I would not be worried about having B4 on one end and Sachs OE on the other. Save your money.
