What is the next step after KW CS ?

[Clubber]

Hey everyone,

I am running KW CS on track but I keep reading all those other mods some people do to improve handling in other areas. I was thinking of getting rear camber arms to give a bit more camber at the rear but I see some running sway bars, adjustable control arms, hard bushings etc.

I know it is hard to generalize a personal driving style but what should one get next after a decent coilover system like KW ?

P.S. I don't wan't a too hard ride.

Thanks,

What does poly RTAB's do ? Control arms are given, ordered from Turner and for sways, other than adjustability for wet driving, I don't see any gains. Am I missing something ?

Here is a good explanation by an M3F member, VinceSE2, who had subframe issues and did a proper reinforcement with an x brace etc...

When the body flexes (which it does) a stock or poly bushing will allow the body and the tubular subframe to flex more or less independently without adding extra, concentrated, stress to the bolts -> threaded receivers-> the threaded receivers connection to the RACP (which is an issue withe the front right mount specifically).
An OE bushing will minimize this, but has the "lip against the spot weld issue".
A poly bushing ads a bit more of the stress I described above, but has a significantly larger area distributing the upward stress of the front mounts to the RACP.
This is why I chose poly bushings.

Side note. I chose a bar/brace at the rear mount (rather than the structural resin (aka foam) as the bar not only ads even more strength than the structural resin and improves the load pats, it also doesn't limit potential future additional fixes/revisions.
Once you inject the structural resin you limit what and where you can weld.
Just my 2 cents. You need too make your own decisions.

EDIT. Certainly do the plates. I highly recommend welding on the Reedish plates, because the Reedish plates distribute the load very well and welding allows:
• tying the plates to the underlying threaded receivers via the rosette welds
• forming the Reedish plates againt the RACP in a way I don't believe can be done with the epoxy method

Sways get the GC's if you really want extreme adjustability otherwise stick to OE or H&R

Thanks for the detailed explanation. I'll see my options then...
