yes, but i believe some sportline/non m-sport packages had the 704 m-sport suspension fitted.

i just checked my own car and the 704 rear sways are very thin. i'd definitely consider a proven aftermarket a bit thicker.

OK. So it seems the rear subframe bushings are very lose, which I think was a problem all along. I am replacing those with street poly.

I was able to get the part numbers from the mechanic who put the new front struts, springs, and rear springs.

Here are the part numbers:
Front Struts: 31316874371
Front Spring: 31336851920
Rear Springs: 33636851929


For the rear, it is current at b4.
Part numbers:
Bilstein labeled: SKU: BIL-19220093
Equivalent OE Part Numbers:
33526868653, 33526874377, 33526874372, 33526791588, 33526868654, 33526791569


I talked to the motorsports shop. They believe they are compatible enough where I will not have any issues. However, impossible to tell without replacing the bushings first.

I will update once I receive the car after repair.
