I recently picked up a 2015 Q70 3.7 Premium RWD and am searching for a lowering solution. I've already ordered a set of staggered 20s. I haven't been able to find definitive proof of the interchangeability of suspension parts between the M37 and Q70. I'd love to know whether the Tanabe TSC158 coilovers will bolt right up. Thanks.

I just bought my '15 Q70S as well. Just dropped it on Tanabe springs - str8 from the M37 parts. WIth the Q70 the only thing that really changed is the exterior refresh.

When they installed my springs - I had to have them remove the rubber bushings off the stock as the new Tanabe springs "creaked" a little. Not acceptable.

Coilovers should be the same - but your installer/shop should be able to verify.

Shouldn't be any suspension changes from M37 to Q70. Light cosmetic changes only.

As Parkstr8r stated above the only changes were cosmetic. Infiniti says so as well here:
