So, I've had the F a couple of months now and have enjoyed immensely.

Today was the first time I've driven it in full wet conditions.

Jay-hay-zeus.

It went sideways at two points in a journey I know very well and at ~ 20mph less than my normal speed as I was, of course, allowing for conditions.

It really was unbelievably squirrelly at the rear. I've never felt anything like it save perhaps my smart which wanted to kill you at 5mph in the snow. I've driven a fair few middies and the difference has never been like this. My fezza was fine in inches of standing water and the Elises I've played with have been a model of predictabilty in the rain in comparison.

Do they all do this (sir) or is there something I should be checking? It is getting new boots tuesday, that's for sure. The current set are more mismatched than an Essex single mother's children.

I would wager that's probably the issue.

What tyres is it running on?

What are your current geo settings?

What's the condition of the suspension? Hydragas system OK?

It should be easy enough to drive in the wet.
Maybe check the suspension bushes.

When was the last time you checked your tyre pressures?

This morning! Not pressures.

My husband has a TF, and his is fine in the wet - it has Goodyear Eagles all round. If he's giving it some around a corner in the wet which isn't often, it gives way a little bit but not sideways.
I'd also say your tyres are the issue!

No ordinary road car in good condition should be like that in the wet; there's definitely something wrong. I'd sort the tyres first, and get a full geo check done whilst you're there. If that doesn't sort it, then start looking at the suspension and possible how worn it is. I've had two BMW E36s which handled beautifully on new suspension, but on worn dampers before I had them changed (100k on one car, 70k on the other), they were rather wild at the back. Don't rely on a garage's opinion on the suspension - one garage told me my E36 325i was fine, but I got it changed anyway and the difference was night and day.

PS - If it's an F rather than a TF it'll have hydragas suspension. You'll have to find someone with a pump and find out the required pressures. Most MG specialists will have one - it's as easy as setting your tyre pressures. I'm not sure whether they use a seperate damper on top of the hydragas, but if they do then they'l need looking at just like an ordinarily suspended car.

Having a random mix of tyres on a mid engined car is begging for trouble, particularly in wet conditions. Aside from that mid and rear engined cars do need to be treated with a bit more respect in the wet than front engined (esp. FWD) cars.

Fit the best tyres you can find and get the geometry properly sorted and the MGF/TF is perfectly ok to drive in the wet - not as forgiving as a FWD car certainly, but not an instant death machine by any standards.

I'd wager it's your mismatched tyres chap. I've got mismatched ones on all corners of my MX5, they came with the car and I'll run them till they die. Driving Bristol to MK earlier the thing was all up on its toes through every corner. Just be aware of it and go slowly on a neutral throttle.

And get some new tyres biggrin

Or until you die. Whichever comes first.

I agree it could be the mis-matched tyres. When I bought my MR2 it had mis-matched rears and was lethal in the wet. I soon bought a new pair of rears and it was fine afterwards.

The biggest problem here is that it's not an mx5!

Had the hydrogas checked when I picked it up and all good. Tyres are a mix of Conti, Pirelli and Goodyear. All good but perhaps they don't play nice with others..

+1 for tyres tyres.

Also, check that some dick hasn't done what they did to my TF and put the staggered wide rears on the front, with the narrower fronts on the back.

That made it interesting in the wet, and it took me an embarrassingly long time to figure it out, all the tyres had very good tread and were a proper makr (Vred Sportrac IIRC) so it never crossed my mind to check the bloody sizes!

My OH managed to spin her old TF on some standing water on a road she knows very well. They are a little twitchy at times but, as above, my starting point would be sorting out the tyres.
