lowering without aftermarket rear control arms
 

hello everyone, i just got a set of tein flex z for my frs
just wondering will i need aftermarket rear lower control arms and camber bolts to adjust camber and toe if i lower it around 1.25"?

I've been on aftermarket coils (~1.5" drop) for 3 years now, no LCAs, but I've also wondered if handling characteristics would be better with LCAs. But not enough to spend money on a potentially futile and expensive experiment

Flex Z have camber plates in the front. So, camber bolts are not needed, but can work in conjunction. (I have both) Also, you don't need LCA, but if your natural camber is different on each side, you may want them. (mine was -1.8 LEFT and -2.2 RIGHT after lowering 1" - I have them now and my rear camber is the same on each side)

Assuming you're looking at these for camber correction?

If so, I wouldn't worry about it. 1.25" isn't a massive drop.

The only time to be concerned with "too much negative camber" for a street car is when you get above -2.5* to -3.0*. Incorrect toe destroys tires much faster than camber.

When you do your alignment make sure the shop dials in factory toe specs and you'll be good to go.
