So I just bought my first set of coilovers ever and I went with the Tein Street Flex Z’s. My car is at 78k miles and I got a muffler delete. Do you all have any advice going into this? Anything I need to buy extra for the coils? I have pretty smooth roads where I live most the time. Until I go downtown.
Any and all advice is welcome 🙏🏽

 

Depending on how low you want to drop it, you'll want to add front and rear camber arms, SPL is the king, but SPC works also. Voodoo isn't bad either and a step above SPC i believe. Also maybe some SPC toe bolts.

I also run Tein coilovers, I have the Mono Sports. I have SPL front and rear camber arms with SPC toe bolts.

 

I’m not planning going further than dropping a little past my wheel wall. I don’t NEED them right?

 

Install the coils, wait a day or so for them to settle, check alignment. Then you can make a decision depending on how much adjustment is needed. I know so people here have installed the arms even with springs. I have KW v3 coils and my car absolutely needed front/rear arms and toe bolts..

 

Do you mean you are dropping the fender lip just below the tire? That is a huge drop that would probably cup and destroy your tires without front upper control arms and rear camber arms. Even with a mild drop like I have to close the fender gap with lower profile tires, you still need those parts unless you want to cup the insides of your tires because you will have too much negative camber.

 

have the toe out too far will hurt your tires more than negative camber.
