So I recently purchased a 2006 CLS55, Awesome car, I love it! Its like my E55 and S55 in one car. Started tuning it and bought an 84mm sc pulley and belt wrapping kit, however the wrapping kit I bought was brand new but the belt was the size for a 188mm Crank pulley and stock sc pulley so it wouldn't fit my car, I/m using the Gates k080530 belt with this set up for the e55 for about a year now without any issue. Should I use this one again for the CLS, or would you recommend using a shorter/longer belt. Any advice wanted, Thanks!

The Gates k080530 is 53.517"
