Got mine installed today, haven't driven it much yet but don't really have anything bad to say in terms of steering wheel feel, it just feels more solid.
Need to drive it to work tomorrow and see how it handles in my usual roads:
I have one question though, in the future when I need to readjust the pre-load adjustment bolts, do I have to loosen the 17mm and 22mm bolts that hold the bush to the sub-frame? or can I simply just tighten the adjustment bolts while the bush is attached to the sub-frame at the specified torque?

Not Correct!!
The Pre-load adjustment bolts do not have a Torque setting.
The 22mm bolt is 150 ft-lbs
The 17mm bolt is 63 ft-lbs
the 14mm bolts are 37 ft-lbs
the 22mm spindle nut is 83 lbft
and as mentioned in the DIY it is "recommended to check the pre-load bolts periodically after initial break in (~500 miles) or after any intense track duty".
Someone correct me if any of the above is wrong.

Correct, those are the right numbers.

Well got to drive the car to work and back today and these bushes are a must.
So first impressions, front end feels more solid, especially when turning into corners, feels more planted.
I could feel a little bit more road feedback from the pedals slightly. Steering wheel and inside comfort didn't change much.
I did a few hard runs and from WOT I was expecting the car to do its usual thing and have tires slipping and me countering the car slipping by adjusting the steering. Now the car did slip as usual but the steering stayed dead center, I literally didn't have to move the steering wheel to counter the slip in anyway, it just pointed forward and I could just rest my arm on the wheel. Feels muuuuch more reassuring, even when i changed to 2nd gear and it slipped for a good sec the car kept its noise straight with very little involvement from me.
Yesterday right after the install on my first hard stop and I heard a screech, like the momentum of the car moved to the front tires and they had a hard time gripping.
Now this only happened once and the first time. Soon after that I tried a few more times and the car stopped perfectly.
Today I did some very aggressive high speed stops and man does the car track beautifully.
I tried at different speeds and the highest was around 150km/h (93mph) to a dead stop and the car is completely different

Thanks for sharing your early impressions.
Can't wait to get mine next week!

Bump steer seems better to me, doesn't get affected by bumps as much, holds its direction better than before.

Ive had mine now for a month or maybe 3 weeks and I love it. I am already used to how the car feels. Absolutely a must do mod in my book. The front end feels tighter, steering feels more direct, and the brakes feel more direct as well. The added NVH is essentially the same as adding a few psi to your tires. Nothing crazy. Even if it doesnt do a thing increase tire life its worth every penny in terms of added connection and communication with the chassis as a whole. From what I have heard it really helps stabilize the car on the track in the high speed braking zones. I am eager to give it a go

Thank you guys for all the positive feedback. We got backordered for a while but will be shipping these mid next week (on Aug 12, 13th)... for those of you on backorder, thank you for your patience, I really think you will find the wait worthwhile.
