It was really straight forward. I did it in my apartment parking spot by putting it on Jack stands and using hand tools. Hardest part was figuring out which way to rotate it to get it out. Took a few trys but then I got it.
Time wise probably took all in all 1.5 hours between parking and getting everything set up. It'll go faster on a lift but I was being super nosey about our suspension and taking my sweet time while bs'ing with my neighbor.
The bar is a 22mm tubular bar with 2 adjustments. I currently drive daily with it on soft and it's def. Noticeable. I forget about it until I drive a completely stock Si and notice a bit more body roll and wallow.
Personally, I think it should have came like this from the factory. Just gives it a nice balance in corners without making the car twitchy.
Setting it stiff is fun, especially with VSA disabled and it'll rotate pretty good with some lift off oversteer.
I'm using factory endlinks. Figured I'd rather have the endlinks be my weak link then possibly the subframe by using heim joints from Sirimoto. Heims will stiffen up a bit more but idk how much more.
For me, going the CTR bar route wasn't worth the time and effort and I'm glad I went the route I did. We shall see how it works in autox as my first race is feb 11th.
Small notes: rotate bar, including connected endlinks towards pass side to get out. Basically pass side, down and towards the front wheel.
Rear LCA bushings have a pretty decent amount of flex in them. Poly bushings are going to make a really bug difference.
Lastly, with the car jacked up the suspension is bound up. Use your Jack on the control arm to unload it and it'll make removing and install wayyy easier. Oh, and double check everything after a quick drive around the block and at 500 miles
