I did some mid speed on ramps today and I was surprised I didn't feel much of a difference even at initial turn in. Then on the highway I drove over a patched crack that ran parallel to the road and I could feel how smooth it was with my steering wheel. It almost felt slippery. I don't think I liked this. Then I noticed some vibration when coming to a stop in a wavy lane. That was no big deal. I just don't think I noticed what reads like a night and day difference such as what PoWn3d saw. If I read correctly, him and I are both on stock tires. Quote:

Well @Laika, you need to do a long drive. If you hit the freeway and drive for 1.5-2hrs your hands will start to get vibrated until they are numb. It takes a good long while, but it happens to me.
I drive from Eugene to Portland (Oregon) regularly. That is around a 100 mile trip. I usually start to feel it about 75-80 miles in. Now, for comparison, my roommate has a mostly stock BRZ. (He has the Perrin Tranny bushing.) His steering feels lighter than mine, and more digital. The solid brackets make the steering heavier. Something I enjoy. Now, to get a SERIOUS feel for it, I have an AutoX this weekend. There, I will have... My car: Perrin steering rack bushings, Perrin tranny mount, Perrin Shifter bushing, Perrin 19mm front and 16 mm rear sways with poly endlinks. Stock tires. Roommates: Stock except Perrin Tranny mount. Friend from out of state: Bone stock. I'll make sure to pay attention while doing my runs.

I like the idea of more detail in steering feel but I am concerned about the health of the surrounding parts.
Has anybody used lockdowns long-term, possibly on other vehicles? Can you speak to the wear rates of other steering components which are bound to see more stress? |

We run these on the Element Tuning Time Attack FRS and honestly there are no downsides, so easy to install, and fits perfectly. This helps to reduce the deflection of steering rack due to the rubber bushing with a bolt through it.
So the more mods you have to your suspension and tires the higher the degree of deflection you will get and it's very substantial with race tires, race suspension, and a big front sway bar. Think of this product as a strut bar for your steering rack in that it won't eliminate 100% of the deflection but will reduce flex in the bushing substantially. The good thing is that it doesn't eliminate all of the benefits of having a rubber mounted rack vs. a solidly mounted rack (harmonics, stress, zero give on impact). I think I need a Perrin Steering Rack Lockdown for our STi Time Attack car as that rack shifts so much I'll come off the track with a crooked steering wheel Thanks, Phil Grabow Last edited by Element Tuning; 08-08-2014 at 10:43 PM. |

Yea, I've had mine in all summer, with both Track and AutoX time. No downsides at all. Just a quick, simple mod for the big effect.

Is there any reason to replace the bushings if you install these? These seem to essentially replace the bushings (even though the bushing stay in place).

Nevermind, read Perrin's response in their thread announcing this product. Minimal difference if you replace steering bushings.

Is it better to replace the bushings for stiffer ones than just adding the lockdowns with oem bushings? I see these cost twice as much than bushings but are easier to install.

It's not about which is better or worse but rather which of the three (OEM, polyurethane, and lockdown) is in your comfort zone. |

I see, so the lock downs reduce the flex but not 100% like replacing bushings completely, therefore then increase in NVH is less? Thanks.

nobody experienced switching from the perrin to the solid bushing replacement or vice-versa ? I am curious to see if there is any differences.
the perrin kit seems to be so much simpler to install I am temped.
