Noticeable rear-end difference
k6martini 1 year ago
I had these installed by Andrewtech while my car was in getting an exhaust leak fixed up, so I cant comment on the ease of installation. What I can say is that they made a noticeable handling difference, which cost less than a tank of gas. I have them installed on my OBS along with fender cowl stays, a front strut tower brace, and an upgraded rear sway bar. They make the rear end feel very planted and combined with my other items make steering very “point & go”. It was especially noticeable during RallyX.

Awesome inexpensive upgrade!

I picked these up a month or two ago for my 02 WRX because I have heard they make a pretty significant difference. I picked Whiteline's version because I dont like Allen head bolts, and the one piece design means no parts to lose, and it should be more sturdy. Install was easy, I loosened the 4 Subframe bolts and since I couldnt find a thread chaser I decided to use WD40 and a couple round pipe brushes to clean out the threads. I made sure they were nice and clean, and then threaded them in, tightened them down, along with the subframe bolts, took it for a ride around the block (felt WAY different) and then double checked the torque on them before going to have some fun. (dont forget to get aligned, I did the morning after) I think the worse your rear struts are (mine are going out) the bigger the difference. It feels a lot more planted, and due to that its a little easier to get the rear end to slide a little when youre trying to. In my opinion, if you have $40 to spend, just get them. You will enjoy them if you push the car at all. I think even one review noted that lane changes on the highway are more stable which I'd have to agree. I didnt notice any extra NVH after I put these in.

Tap that!

It took me a fair bit of time to chase the threads as there was 7+ years of dirt and rust...take your time and get it cleaned out real well, you dont want to snap the weld on the nut

For just a few bucks and 10 min of your time, you make a difference that any driver can feel, I put them in a impreza Sti 2002 (really old) and I can feel the difference righ after I installed them, the rear feel in place, and give me confidence to take the turns faster, without the feeling of the rear end is going to slip in oversteer.
