IPD HD Lower Torque Mount Kit, transmission + subframe mounts - P1 S40 V50 C30 C70

Volvo's original lower torque mounts were designed with controlling NVH (noise, vibration, harshness) as a high priority. They do this well with plenty of rubber in the mounts, but as the rubber ages and fatigue cycles it becomes less elastic, cracking and stretching and allowing the engine/transmission to swing and rotate relative to the chassis. This driveline "shunt" is especially noticeable at initial throttle tip-in, so if you feel a lot of slop here when rolling in to the throttle, take a look at these mounts.

IPD has come up with HD replacements for both mounts, featuring billet aluminum brackets and polyurethane bushings better able to cope with repeat load cycling and age. Polyurethane is stiffer than rubber, providing a more precise, "locked down" feeling to the driveline...but we've also sized these bushings as large as possible to spread these loads out over greater mass and bushing surface area, giving only a modest increase in NVH with that greater control.

If you've got an autocross monster and want to stiffen things even more, the subframe-side mount is tuneable by inserting delrin rods in to the voids to increase its effective spring rate. See Recommended Products below if you're interested.
