Just to add, you can't compare durometer ratings between the AWR and others like the Cobb/Mountune/Vudu common style. The AWR uses small bushings, so you have much less amount of poly before you are at metal, which is fine, it's just that their 70a more comparable to an 80a in those other styles with much thicker bushings. But yes, the AWR 70a is perfect for most who aren't afraid of a touch of vibes, the Cobb is the softest, the Whoosh Street is just slightly stiffer than the Cobb and is perfect for many, then you have Mountune and Vudu, very similar to Whoosh but at a much higher cost. The more vibes you can stand the better though, makes the car feel SO much more solid in traction and shifting feel. After breaking my Torque Solutions, which is slightly stiffer than the Cobb I now have a Pwnall Performance one, likely similar to the Whoosh race version and I took a 1500 mile road trip to get it broken in and it's still pretty bad taking off and through the 2400-2800 RPM range. All I can think of is that I over torqued it, so I'm gonna go back in and torque it to spec (55 lb/ft) and see if it's better. Also, likely will get better with even more miles, so it does take a good couple 2k miles to fully break in.
