any aftermarket ones for the 400?
i need some new mounts too man

i dont want to be powering my engine and then put too much into it and just have the mounts break

just wondering if there is a stronger alternative besides stock, getting the parts isn't a problem if they are OEM, my dad works at Nalley Lexus Galleria in Atlanta

 

would sc400 mounts work on a sc300?

 

Curious on just how much power you're planning to make in the SC400 that you'd think you'd snap fresh oem mounts, its not a known problem.
SC3 and SC4 are not interchangable. Use the MKIV Supra mounts, they're better and cheaper.
