I bought one and installed it my self (flaming one 20:1 )
It is fairly simple to do . The 20:1 is easier to turn and the good thing is no more steering pump , so you have more room in the engine bay and taking off some weight aswell !
Not that much but still better than nothing ! You feel the road pretty good too ! I ve got nothing bad to say about it !
But you will need a alignment for sure . Btw i did it my self with tiny rope and measured tape it worked well . U can go tu youtube and type : how to alignment my car my self . And they explain everything ! Those stang got fixed axle so its easier to do good luck 😊
Sorry if my words are writen bad , english is not my first language .
