Are camber tops essential? What if I have coilovers without camber adjustment?
Camber tops are not essential however without them you will be running quite a bit of negative camber (-3 or more depending on the height of your car).
Does installing this kit require a wheel alignment?
Yes, it alters both your camber and toe so a wheel alignment will be required after installation.
Can this kit be used without modifying steering parts (no extenders)?
Yes it can however if you are experiencing steering bind from running lots of camber and/or caster then our offset rack spacers will help to eliminate steering bind
Are there any cons of your bolt on RC Correction kit Vs the front knuckles?
The only disadvantage to the bolt on RC correction kit is that it pushes the bottom of the ball joint out 30mm. This increases the scrub radius of your wheel 30mm (just like a bolt on wheel spacer or lower offset rim would do). If you are already running low offset rims (less than +20mm or wider than 10") then you may have clearance issues.
Which tie rod position does what?
The inside setting (towards knuckle) has more lock, more response and is noted to be more aggressive.
The outside setting is similar to our V1 roll center correction kit, which still increases steering angle, but without the aggressive steering response and lower ackerman.
