Review
tl;dr: if you're sensitive to cabin noise/vibration/harshness (NVH), immediately abort. Twisted Tuning severely under-sells the NVH increase by describing it only as a simple "increase from stock." If you want your Supra to be a sleek and quiet cabin cruiser, just close this browser tab and stick with your rubber mounts.
But if you're ready for your Supra to feel raw and unfiltered, maybe this is just what you've been looking for. Even then: I want to stress how raw these mounts feel. The politest way I can describe these mounts is "controversial." Still interested? Well, okay, if you insist...
Dear reader, I am here to tell you that these mounts will leave absolutely no doubt about what your transmission is up to. Did the gear change? KER-CHUNK. Are you decelerating? Zheeeeewwwwww (planetary gear noises abound). You about to drop the hammer in 3rd? Buckle the #&@! up because you're gonna feel every fuckin' tooth of that gear set. Your ass and hands have never felt more connected to this car. Feeble passengers will beg for mercy. Fillings will rattle out of your skull. I can't promise your hands won't go numb cruising in Sport 6th. If you're having a bad day, you may still wish you had those OEM rubber mounts.
But sweet mercy if these mounts don't feel raucous, wild, connected, visceral. Alive. People have moaned that the Supra feels too disconnected from the driver. Well well welly well well, get you a big-ass front sway bar and some Twisted Tuning mounts. You'll live to regret that you ever uttered that thought.
In terms of performance, I could swear that everything felt a little snappier. Maybe it's my uncalibrated butt dyno. But I do come from a long line of cars where rubber gets banished for polyurethane, and I've never regretted it.
IN CONCLUSION...

Install tips
- Car must be fully in the air on all four corners for the appropriate clearance.
- You will need a floor jack or bottle jack under the vehicle with a thick and wide plank of wood. The plank should be jacked snugly against the bottom of the transmission (oil pan) to ensure the trans does not move on the vertical axis when the chassis brace (magenta arrow) is removed. Use common sense and keep it snug, not crushing, so you don't destroy your transmission oil pan.
- Tools needed:
- 13mm box wrench to hold trans mount (blue box) bolts in-place
- 13mm deep well socket to drive and loosen the trans mount nuts (red box) and trans brace bolts (green box)
- 8mm socket for the felted splash guard over the trans
- Socket wrench
- Torque wrench
- A universal socket will be helpful for the brace bolt above the exhaust.
- Total install time of about 30 minutes (raising the car not included).
- Torque specs:
- 19 Nm: one nut for each mount (red box)
- 19 Nm: one bolt at each corner (green box) transmission chassis brace (magenta arrow)
