Default car stutters coming out a high speed turn

anyone have this issue. so frustrating. car is a dc5.coming out of a fast turn, the car jolts. kinda like when you first learn manual the car jolts. it only happens when i'm coming out from a high speed turn. i stiffened the suspension towards hard and minimized it quite a bit but still there. i'm guessing its the shocks on the FA coilovers? i know shocks are everything on this car. from research on 200tw the ideal rates are 14/18. i'm going to sell my FA coilovers and get amr. alot of people with the dc5 have had success with those.

car has 17x8 +25 with 225/45 hankook rs3.

the car has a quaife lsd with rtf fluid and its fresh.

car as the following suspension mods.

Fortune auto 500 coilovers with swift springs and 10/14 spring rates
Spoon sports rigid collar kit front
Spoon sports rigid collar kit rear
Spoon sports strut tower bar, front
Spoon sports lower arm bar, front
Function7 lca's
Function7 subframe brace with bigger brackets
King motorsports control arm adapters
PCI racing front lower control arm spherical bearings
Dc5r control arms
Dc5r b-pillar aluminum floor bar
Dc5r front sway bar
Progress rear sway bar

I don't think you need to sell the FA to go to AMR... just my opinion.

are you sure its not a fuel sloshing issue? are you on hondata? can you data log it?

This^^^^ stuttering doesn't come from suspension.

Is the car jacking around the corner or are you losing power?

If its fuel related look into one of these:

or something similar.

Go out with a full tank of fuel, log your sessions with the on board kpro datalogging and watch your AF when you get the hesitation, if it runs lean during the hesitation with a full tank, check the fuel pump and wiring (power/ground/signal wire). If it only does it with say a 1/4 tank or less get a hydramat (your having slosh issues).

If the hesitation occurs either way, check to make sure your grounds are solid and clean... If so, keep digging, look at coil voltage, pull the injectors and apply 12V and a ground to the injectors one at a time to make sure you get a click out of each one and check your harness connections.

I was having a similar issue part throttle before the cam angles were situated just before cam cross over where the car would break up and hesitate, once I had those sorted it made a huge difference and smoothed things out. One of these things would likely sort you out.

A sensor failure should show up in the code logs if it trips a mil.

data log your sessions to rule out fuel.

whats your LSD setup exactly? and FYI, fresh fluid isn't always the best.
