Genuine mounts are fairly expensive - there are 5 on a type r.
Two lower front mounts, $86 each
Right side engine $217
Rear $219
Transmission $415

If all of them are on the way out id say go a hasport replacement kit as its cheaper than genuine, plus it would be alot stronger. However if 1 is blown you can always go something like kelpro as they are fabricated to oem specifications.
Saves you replacing parts that dont need to be replaced, which in turn, keeps money in your pocket.
