can you share all the wheel alignment measurements from before/after the 4 wheel alignment? camber, castor, wheelbase, toe.

Front Caster is good.
Front left camber is way off the front right. Front right is good. I would like to see your front left matched as close as possible to your front right.
Front toe IMO is better measured in mm. I have NFI how to read the degrees they printed out for toe in your sheet lol but they look almost identical so that might be OK depending on what the total toe is.
Rear left camber is good but the rear right is a bit too much for a non race car IMO. I'd like to see your rear right matched to the rear left in this instance.
Rear toe looks pretty close to eachother so thats OK as long as they're not over 2mm.
Not sure what is meant by the "SAI" and 'Included Angle'? But I reckon one of them at least is referring to King Pin Angle judging by the measurement.
Its a bit of a different printout to what Im usually used to getting.
So from that it looks like your front left and rear right need attention IMO. But of course Im no suspension expert lol
Im sure some of the other boys will fill you in with some better info.
The other thing I thought about was that maybe you have a 1.5 or 2 way front LSD installed?

Yeah my left camber hat is a hell of alot off compared to my right so as far as i can think back on things that have changed/could cause this issue im thinking the wheel aligment may have something to do with it?
My gearbox is a evo 2 rs non LSD box but has a LSD fitted, From what my engine builder can tell/feel he said its a dam tight LSD thinking some kind of plate type? Sound right?

Yup does clunk a little? Was out of a ex written off rally car?
Im running redline shockproof blue stuff in both gearbox and rear diff?
Yuk, I hate that redline shockproof stuff. Its pretty bad at keeping mech LSD's quiet or happy, plus its like thick snot when you try to clean it off the internals of a gearbox. It does make an LSD engage more harshly even with the lightest preloads and it might be exaccerbating the effects youre experiencing under decel in your (what could possibly be) a 1.5 or 2 way front LSD.
If it were me, I'd piss that shockproof stuff out of your gearbox ASAP and replace it with Motul FF-LSD Type 2 instead.
Using redline shookproof out back is an old trick to get some better LSD action out of a factory plate type rear LSD in an EVO, GTR etc though lol.
