As far as the feeling, it could very well be tolerable for you. It took me a bit to get used to it but now I don't even notice, it's like a racecar for the street. I also have the damping set to the middle so it could be even softer. I would urge you to find someone nearby with inserts in their car and ride shotgun to see how you like them. |

I concluded the way to avoid that is to loosen all 4 bolts (just as you advised). That makes it much easier to get the bolts properly aligned with the holes and hand tightened. I was just trying to explain my thought process and congratulate you on reaching the same conclusion. Apparently, I didn't do such a great job.

I can see how there may be a difference with the stabilizers. Toyota shows a graph where they show less chassis deflection when turning sharply/hard.
Probably nothing huge. 5%? 10%? 15% better feel? You'd need to be quite comfortable with the current setup of the car to potentially notice anything. For me when I crack the windows and hit bumps the window rattles as the door shakes. Stuff like that bugs me and is the main reason for the mod. Plus seeing how much the door moves around normally and in autocross I figure it's an easy two bird one stone mod with no NVH downside. Based on feedback on bushing inserts I'll probably be doing diff, sway bars, trans, then steering lockdown. Everything else seems like it'll add too much NVH for me on a daily. |

It's similar/adds to the effects of installing a front strut bar in terms of making the car feel a little more sharp, solid and planted when driving spiritedly/hard. Would definitely recommend if you're a "feel" chaser; would not necessarily recommend if you're a lap time chaser. As a bonus, they both help with uneven pavement feel less crashy (more refined). |

It worries me that claims are made by these mod manufacturers that are completely unsupported with any actual measured data being supplied. These claims are very easily measured and published, especially if it's your business to make and sell these things. But they don't do they? I know part of the argument is about "feel", but if you can feel a change in something, you can measure it. (Particularly if your paying through the nose for it claiming to physically change something). If a racing driver has great feel in the wet, they are faster in the wet. If the thought about the extra "feel" of these mods is because some drivers have an extra sublime ability to "feel" the difference, while the rest us us don't, is being more than a little presumptuous. Quote:
A graph showing a change in "chassis deflection" could actually prove or disprove their potential usefulness. 5%, 10% or 15% better "feel" is an enormous improvement in a car... any car manufacturer would kill for an easy increase like that. So you have to wonder why they haven't all rushed to build tighter door jams into their own cars.... or even into the updated twins? |

Hey gang, why do most wheel/tire setups go with an equal tire size on all four corners? Is it just for lateral stability?
Wouldn't a thinner front/wider rear tire be better as you'd still have some of the responsiveness and quick turn in from the front? The McLaren Senna still runs a 245 front tire and if I'm not mistaken the 600LT and 720S also run fairly thinner fronts. In fact, I believe most supercars do this. I'd imagine that a good quality tire compound would take care of added grip and you could stay with a 225-section front and feel free to go to 245 rear if needed. Any handling/steering feel downsides by going with a non-staggered setup on our platform? Last edited by WC-BRZ; 04-24-2021 at 02:04 PM. |

I think staggered is the ideal recipe for some additional understeer on these cars

Tightening build tolerances is VERY expensive. These shims are a much cheaper way to achieve the tighter clearance. Pair that with the fact that 90% of drivers won’t notice, and I’m not surprised they don’t bother.

Way back when I was researching these, I came across a video of an frs doing auto cross. The POV, from a gopro suction cupped to the car, focused on the door/body seam and the amount of gap variation was a little scary. After these were installed, the door gap was stable. Sold me.
