Really sorry to hear this, this seems to be a general issue though. lat night I finished installing my JWT Pop charger, sounds great and a bit more pokey (i'll wait for the ECU to spoil that) any way, on my way through Reading, up to Caversham and then Emmer Green (just before the Esso at the brow of the hill), I had a fairly large fishtale, now my TC was on, I have Michellins and although I was going some I was not being overly right footed. The road was wet but not a river and I have taken the hill faster in worse conditions in an M3 and an S2000, the S2000 is very scatty in the wet, and never freaked like this, so other that the road being abnormally slippy, there must be something that makes the Z a bit lairy compared to the above. The tread on my tyres is fine
