Got the OEM rear shocks replaced by Bilstein Sport a few weeks ago since one side was blown,now the front left start to give out and I think it's time to do the front ones,however bilstein front struts are out of stock everywhere here in Canada and nobody even has an ETA. I happen to see that Koni's are on special now and I wonder if it's okay to run them in the front and keep the Bilstein's in the back,wiill overall performance suffers by doing this?
