Removes a good amount of wheel gap. Springs take time to install safely so have the right tools or be ready to pay for 4 hours of labor. Definitely improves the handling over stock. Great low cost suspension upgrade.
Pro: Great handling springs at a nice price.
Con: The rear spring sag giving the car an uneven look.
The springs are nice for the price. The sti looks more aggressive. It does change the ride slightly. A little bouncy ,but not to bad.
All in all I like them and the look they give the car. I would recommend
Okay so my intention is not to scare you away from these springs but I am going to give you my honest opinion. So I have had these springs installed for about 4 months now and I like them. I wanted these because they are a progressive spring rate so they aren't too stiff. The pros are handling when on backroads is night and day compared to stock. They eliminate about half of the 3/4 wheel gap and change the whole look of the car for only $250. They don't cause any weird noises.They weren't that hard to install as it took me and a friend about 5 hours to install all 4 sides. Now the cons. You will feel just about imperfection on the roads but it isn't a harsh feeling, you just know that the bumps are there. You can't really have 4 people in the car because it will tend to bottom out on bumps. Car will feel about 30% stiffer causing it to have some bounce. Bump stops did not fit on my 2018 wrx limited with inverted struts. Instructions were not included. (Just follow the RCE instructions online). Try not to load your car with 4 people because its just too much weight, back end will bottom out on bumps on freeway and front will bottom out as well. With everything being said if I could go back knowing how they feel I would still buy them again because I love the drop of the car and the pros outweigh the cons. I mostly daily this solo and do backroads with 1 other person in the car and they are perfect.
Front: alignement I set up the front with -1 degrees camber in front with stock camber bolts. Can be dialed out to 0 with stock camber bolts.
Rear: alignment was within spec with -2.3 camber in the rear. Max camber that falls within spec is -2.4.
