Excessive body roll
is it just me or does the sti (04) have excessive body roll, you really feel it on the twisties & when cornering hard.
Any ways to stiffen up the suspension
Cheers

Prodrive Spring Kit Stephen apparently works a treat - ask John (EVOJKP). Even my car felt very stable when driven properly last night on the track - like jelly when I got the lines and braking wrong.

Cut the floor pan to allow the visible part of the shell to be removed. Then graft that part of the shell to a Zip cart thats just been stolen from Knockhill and hey presto.. your Sti will handle like a Go kart.
Any use to you???

uprated anti-roll bars and droplinks... (as well as the springs)
dunno whether you need geometry checking / resetting after ARBs but you don't after droplinks
ARBs, depending upon setting, reduce the body roll and understeer but if you make them too stiff at the rear, you can make it easier to oversteer
(unless you are a talented driver and/ or like the handling that way as it can be rewarding but you've to be ready if it breaks away - understeer = safety for Joe Public as it gives them a warning to cool it 
) By stiffening things up to much, you take out the compliance of the suspension to absorb the cornering forces, making more load transfered to the road / tyre interface and if this is too great for the tyre to cope with, it breaks away and slides...
Droplinks are on the ends of the ARB and bring in it's effects sooner by preloading the ARB, i.e. less mushiness to get through before it gives some benefit - they don't alter the stiffness of the ARB - just it's "starting point"
It's also possible to do the front ARBs and droplinks whick will push the steering response into more understeer if the front is relatively stiffer than the rear...
These are all layman's terms so it's probably better asking in the suspension forum...
