search and you will find answers

but I have had them for a while and it definitely corrects the suspension geometry in the front when you lower it and gives the car a factory setting to tune the alignment and camber, almost like it was never lowered. If you look at my signature picture below, you can notice the front is dropped almost to the tires, but there is little negative camber. From that point I have now added negitive camber after an alignment. Do not get them if you don't lower your car.

They go on to provide further camber/ caster adjustably if you are only running drop springs you may not need it , a mild drop is not going to totally destroy your geometry.

Anything more than an inch and a half it is a gray area , If tire wear becomes an issue or if bump steering , caster clearance , etc. Then yes you need further adjustably for your alignment tech to work with.

While you are at it if you are going to all this trouble , make sure your tire pressure is perfect before your alignment and ask the tech if you can sit in the car while it is aligned. With such a light car you would be surprised how the weight of a 200lbs man can really change things up.

With any purchase or modification to your car , do your research , make your own choices on what works for you.

It is designed to raise the front roll-center geometry by using new specially engineered ball-joints and tie rod ends while still maintaining original steering geometry.

This improves weight distribution, maintains a better camber angle and ultimately improves front grip. The overall outcome is significantly reduced understeer through reduced front wheel compression, as well as improved steering feel, steering precision and vehicle stability.

This Kit is a must for lowered vehicles its kind of pointless to use for standard height car

is it true that you need at least 15" wheels for these to fit? i would like to stick with 14s if possible.
