The Revington springs raised the front of the car so it's about 10 to 15 mm
higher than the rear,but they also firmed the front up considerably.I am
using adjustable Konis all round,set one off their softest setting.

I agree with the theory,I just hated the feel. The guy who sold me the car
demonstrated its handling and throw it into corners in a way I could never
fell comfortable in doing,it's just down to personal preferences.

.
I agree it's a preference thing.I prefer a ROAD car that will slid a little
in a predictable and controlled manor when really pushed, rather than
a car with more rubber on the road that if it does let go it happens
suddenly and with little warning.I won't argue that your method will be
quick from A to B but,for me personally, I'm much happier with a
nice light handling chuckable TR.

Now that's a good idea,if only there wasn't all that damn water in the way!!
