We will agree to disagree once again
I agree with Speedsix that the car has a far more 'neutral balance' giving you the ability to adjust the car through the bend on the throttle with far more certainty i.e, not wondering if the back end will snap round and bite you.
IMO the S3 strut brace sharpens the intial turn in a little which also gives more confidence and a better feel as to what the front tyres are doing.
Speedsix - what you will enjoy is watching std civic type-R's and the like follow you into roundabouts and wondering how the hell you went through with no fuss when they are .....
Stock front, 25mm rear also gave a more stable neutral balance (again, with stock suspension) and certainly removed that horrible wafty/wandering rear end - like you say removed that feeling that it was going to snap at any moment.
I felt the extra front stopped it rolling so much at the front that it didn't dig-in.
Anyway, Neuspeed sell the two different sizes for a reason... Choice is good.
Plus, you're bigger than me
Adding a thicker front on it's own will increase understeer but it's the relative thickness front to rear that is all that matters, you are moving grip not losing it. Stock car has a thicker front than rear ergo, understeer. Swapping the front for a 25mm and adding a 28mm to the rear (with the stock rear) gives much less understeer because the rear is now thicker than the front. Some people really struggle with this concept as you've found outI believe they also sell a 'Race' blue coloured 32mm rear so that's three sizes
I was told time and again by various people that a 25mm front ARB would make the car undrivable because it would understeer off into the bushes at every bend....and indeed in the wet apparently my car would be like manouvering a supertanker.......I have a two word answer to that "Utter Tosh"
My views on the fornt ARB are concurrent with this Gentleman's findings;-

I will state again for the hard of reading the front Strut Brace also helps sharpen turn in and promotes confidence
A car doesn't roll more at one end than the other unless it's bending in the middle!
It's not something that's open to interpretation really, it's just science and anyone that says otherwise is plain wrong and I give you permission to slap them about a bitPeople said 25mm front 28mm rear would promote understeer too
I disagree
then what do I know I only did 20k miles in an LCR with them fitted
(perhaps arm wrestling at the next SCn official event will be the answer to resolving this question.... )
