Walshie - you didn't say which Bridgestones are on your car. I test drove an S which had Bridgestone Turanza tyres on the rear, which stepped out on me at 70 while steering back into my lane after overtaking, and then kicked out the tail on a slow roundabout, with a slightly damp surface. Could have been the geometry, could have been the tyres.
But the car I eventually bought is nothing like that. It feels safe and secure in the wet, not completely lairy! And it's running on Bridgestone Potenza RE050s.

Hi there, all I know is they're Bridgestone's, and looking at the tread, I would assume the Potenza RE050.

what appears to be ample PSI (subject to checking).
I deem myself pretty good knowing how cars do handle
The only possible problem was lift-off oversteer in extreme wet (i.e. central barrier if in fast lane).
How can the geometry possibly do this to the car

You deem yourself to have a pretty good knowing how cars handle but dont know how geo affects a car. As others have mentioned geo is critical on these cars. Dont go to one of these "4 wheel lasor aligned for

[QUOTE=walshie,Aug 19 2008, 05:09 AM] A honda s2000 is set up for road use, so even if the suspension was not as tight as it should be, it shouldn't be fish tailing. Of course, you could understand this for a F1 McLaren.
I'm absolutely staggered how the geometry of my vehicle could affect the handling so much. What I mean is, when it was made, the geometry of the vehicle was great, yet after a few years, the gemoetry is no longer good enough

it shouldnt fish tail in the dry - even with a supercharger i dont get fishtails - but occasionally the tire pressures differences induce a side to side motion correlated to on/off throttle - but again this really would nt make the car fishtail - passengers would probably feel seasick though.
I can get it to fish tail in third in the wet in a straight line (havent got the mettle to try fourth!)
Tread depth will be a problem in the wet, but lets concentrate on the dry first...
So check that
1) both rear tyres are the same brand, same model, same width
2) both have the same pressure
3 ) Since yours is an 04 at least 245 tyre width
If this is the case then proceed to
A laser alignment

The porsche boxter had similar tyres to the S,
and this is what happens when they get low
porsche2
My friend was off shopping with the missus when he hit a small amount of standing water, completely striaght road, but just lost it.
the dint in the corrogated steel was done by a Ferrari a month earlier also with bridgestomes,
the new Bridgestones are great in the wet but older ones slightly worn are suicidal if your not

when the pics were taken they were still stuck in the car, unhurt
