And never looked back ever since.

Is it something like this? https://rallitek.com/products/beatru...-sti-2015-2016

There was more NVH with the white lines than the STI stoppers. And the behaviour of the car had changed from proper rotation to understeer. And my car was stock, there were no other parts installed.

The rear was so planted that I could not break loose unless i was really trying very hard and I didn't like the change in character.

Then I did a search on the forum and found someone who had installed these STI stoppers and decided to put all four uppers and at the time went with the STI subframe bolts.

This combo was much better. They say that the STI longer subframe bolts work in the same way like the Spoon Rigid collar kits.

This restored the character of the car and decreased the movement/play in the subframe stock bushings to an extent where I could decide when and how much to make the car rotate in a corner.

Hope i am making some sense

These STI stoppers are installed on the BRZ Ts from factory.

Some discussions about the STI stoppers.

I preferred to trust the R&D of STI engineers than others.

Here are some part numbers.
