A worthy upgrade for someone out there... GLWS (if there's interest).
By eck, you must give your car some welly if you found the need to change the the set-up. Or do you take it on track days etc? Admittedly I haven't taken mine on the track (nor do I plan to), but I've never been faced with overheating or fade from my standard set-up, I think they're great with good feel and are pretty progressive.
Perhaps I'm not trying hard enough
