Kit comes with most things required. comes with the 2 mounting screws and x2 washers. What you need is another 2 big washers purchased at Bunnings, so that the mounting screw does not move because the screw hole doesnt fit properly. Very easy fix. I have fitted the Motorsport engine bush and the Top strut brace, eibach springs and bump steer correction kit. I have found that the vibrations are highly felt in the car after fitting the Motorsport engine bush as its transferred to the chassis and is especially felt just before you lift off clutch as the i30N engine automatically revs a little for you. After ive installed the lower brace with the Top strut brace andthe Motorsport racing bush, the vibrations with what was there before installing lower brace VS the vibrations felt after the lower brace is installed = 80% vibrations gone. I have to admit the lower brace works really well and i felt the car turns in even sharper. i didnt upgrade front or rear swaybars as i dont think i need them since i have the Top and lower strut brace, eibach springs and the bump steer correction kit. The only thing that goes up and down is now is my suspension, Only limiting factor how good your tyres are as after the install you will find that your tyres will squeal quite easily. I have driven the FK8 Type R and before the these changes i felt that the Type R has sharper handling than the 30N. Now i think that the 30N handles better than the FK8 Type R! :)
