Is it understeering? Swaybars are a double edged sword.

You forgot STi. I just swapped all rubbers in the front and I'm very happy with them. No vibrations, just a little amount on noise. Expensive...

My car doesn't understeer at all (unless I make it), but, if required, gets its arse out on demand. All a thicker rear bar does is sacrifice grip at the rear. Preferably you want to add more grip at the front, not take away grip from the rear. Well that's my idea anyway. Not 1 of my cars that Ive set up for sprints has been any good on the street during wet weather or on dumpy roads, all were pretty stiffly sprung. Hell, in the end I'm no expert, set your car up so you have maximum grip with your desired characteristics. It just seems to me the most common option when people talk about performance IRT handling is everyone oversprings/over dampens or adds thick bars to get their desired characteristics, generally foresaking grip in the process. The funny thing is, you might get the desired results by removing a psi or 2 psi from the front tyres, and, not lose any grip at the rear. In finishing this longer than necessary rant, I would focus on a spring and correctly valved damper, combined with tyre pressure testing, prior to bandaiding the issue with sway bars that may do more harm than good. Yadda yadda yadda, I'll stop now......

My first thought was the STI replacement bushings but they need subframe removal and pressing the new ones that I don't want to do.
@nikitopo I didn't know there are STI inserts and they are original fitment on tS, are they same part number ST20176AS000 for front and rear subframe bushings and available only for the upper part (which I prefer)? Did you install also the thicker bolts ST20159ST000? I think this is exactly what I was searching for if they are more compliant than the other aftermarket bushings! @86MLR I totally agree, the keyword when setting a car is balance, that's another reason why I don't want to install very hard subframe bushings or bigger sway bars etc. Every part of the suspension affects differently the behaviour when cornering, making small changes in every aspect, suspension, bushings, adding camber / zero toe etc is better than say very big sway bars! |

Yes. These inserts are for the upper part and I installed them together with the thicker bolts.

Whiteline subframe inserts are good. Minimal NVH increase. It's hard to describe the difference bushing changes like these make from the driver's seat, but there's just a little more connected feel, consistency, and confidence with the back end. More bushings ramp this up even more (and some have added benefits like reducing dynamic camber/toe changes) but you're also more likely to add more noticeable NVH. But you can do most of the rear end without making the car annoying with the right bushings.

For me the most NVH came from the subframe bushings. The NVH from trans mount/shifter/diff bushing or insert whatever was minimal. As soon as I put in the rear subframe, bang!

From what I can tell, it's not one or the other, it's the combination of stiffening multiple things that create noticeable nvh. The diff bushings created undesirable nvh for me, but they went in after the subframe ones, the rest of my bushings are stock. |

Hm. Maybe I'll change my school of thought. I'm always up for a change, maybe I'll skip the sway bar on this car and do subframe bushings, support for this seems overwhelming! As I said, I wasn't really trying to keep balance or have the car handle all around "better", I was chasing a specific feeling. I'll stop threadjacking, but everyone here seems to like them so much, I'll change my ways and try some bushings instead! |

I may try the tS bushings & bolts or from the Whiteline KDT922 kit only the front bushings and may be later I'll add the rears. |
