I'm no 'road tester' and its been a while since I fitted them but the overall package is a vast improvement. I also fitted new Michelin Pilot Sport 4's in 265 x 35 and 235x 40 which are obviously influencing my impressions.
I didn't carry out the mods 'one by one' so I cannot rate them in terms of their individual contribution, however the vagueness and floatiness experienced when cornering has been eliminated. The car remains virtually level at all times, feeling planted and almost eager to be powered out of any corner. A thicker rimmed steering wheel allows me to feel more connected to the front end. There is no dive under braking, nor squat under acceleration. I drive in Sport virtually all of the time and although the ride is more harsh than standard, it is perfectly bearable, even all the way to Italy and back.
Appearance wise the lowering has a huge impact as the arches are now filled and the car appears far more purposeful. It handles speed bumps without issue but doesn't like acutely angled driveways/roadways, at times scraping the undertray. I have a modified tubular exhaust, replacing the squashed section where it passes under under the steering rack and is therefore lower than standard, but that has never scraped under suspension compression, and only once over a protruding manhole cover that I failed to notice in the dark.
The forum's experts advised ARB's before springs and I wouldn't disagree but certainly together they allow the car to emulate the character of a sports car rather than that of a tourer. With the FD winter sale now on, you're timing the mods just right - I'm seriously considering the Drive by Wire.
As they say, if you're ever in Newcastle give me a call and you can have a drive.
