after a week. finally i got my sway bar done yesterday. so there's Stech springs and progress sway bar on my car now. and here is my Exp. i just try that out last night. I was going 237 west onto 101 north. what's my speed? 80 MPH

. just for that short distence. before the sway bar. i could only go 67 or 69 MPH max

.and now is 11 MPH more

. and i feel that i can even go more if i have better tires. and daily driving. i feel more stiff in the rear which i think is better.and i love it. now i have more fun every time i attack the conner. can't wait the coilover for it.
after all that. i have a question. since i installed my sway bar. i heard there is squeaking sound form my spring. i don't know if you guys have the same problem before or maybe only my Stech doesn't like my sway bar

. can someone tell me which bolt hole is the spring pad protrusion original located? maybe i put it on the different hole. now i put it into the one that closest to the front of the car.
