Installed the Perrin pitch stop mount. It looks very well made. Instructions say to remove innercooler, however I did not need to do that. Install took 5min. Contrary to what some websites have said, there is zero NVH. There is a more solid feel from the drive train, but no vibration at all. I was surprised.
Installed SPT fr strut brace. This also took 5 min. Cornering feels somewhat more solid. I was skeptical, because the bar is aluminum. Not bad for price.
