I have to agree with above, I mean unless you are just driving it realllllly hard which seems unlikely I suppose, then it really shouldn't be doing it even with a standard suspension set up, so before you start buying expensive performance mods like coil-overs (as cool as they are) its prob best if you get the standard set up right first otherwise you'll just end up in a mess not knowing what is causing it to do what. If any of that makes sense...

could it just be lift off oversteer?
if you lift off mid way round a corner, or brake, you unweight the back of the car and induce oversteer. the natural reaction is then to slow down or brake, as your sliding, but that makes it worse. You need to steer into the slide and put your foot down, and power out fo the slide.

I second the alignment checking also.

Woudl it be worth getting rear camber brakets, and getting that set up?

are you really chucking it in or going through smoothly - if you are chucking it in hard then it will be unsettling the car making it more prone to oversteer especially if the back is light. If you are smooth, maybe knocking a bit off your entry speed and smoothly applying power through the corner it should stick like its on rails, although personally i dont think you should be driving fast enough on a dry raod with sticky yokos that you do get oversteer mate - not a dig by the way

i bet £1 youve got toe out on the rear wheels.

rite this was bugging me as to whether this should happen so took the mini to a very deserted big roundabout on a disused industrail estate thing earliertoday when I should have been revising. I have a standard suspension set up and no matter how hard I pushed it I couldn't get oversteer, could get it to slide a bit afetr a couple of trips round the round about but nothing like your describing, except when I went stright from power to the the brakes and te back felt a bit light. So unless your braking through corners I cant see its your driving style and might be something like Mini-Dave said. I used to have a little book about the effects of toe in and toe out, camber etc on handling, will see if I can find it.

probly just because of the recent rain, after having a fair bit of sun, the grease on the road will be considerably worse. To help prevent it, firstly dont drive as fast, dont be slowing down whilst cornering, also check the brakes arn't binding at the front or anything silly like that

All tyres are brand new well 2000 miles of use. It was doing it in the dry driving quick in the wet is a no no. Im not braking on the corner as that is very bad same as lifting off mid corner (used to have a 205 gti and they suffer from rediculous lift off over steer). Been around all brakes, and all are free and working right. Probably think about changing the suspension?

could be something simple like u de-accelerating half way through the corner and then hitting the power hard, that always used to make my other cars slide like crazy. i must say my mini doesn't do that half as badly! so dampers?

[stefaz]

ahh lovely adjustability. would be interesting to know about the toe in/ out effects though please jimi. cheers

toe out seems pretty likely like mini-dave said. Makes the back want to step out from the reast of the car. Probably got worn bushes on ur radius arms as well so your experiencing posotive camber. How old is your car? Buy rear camber and tracking brackets and if u need to refurb your radius arms. If you look from behind your car i bet the top of the wheels lean out from the bottom of the wheels.

minidave has it..

usually the back end should be (on a roadie anyway) at most parallel tracked, but normally toe in - this is nice and 'safe'.

I only setup racers with toe-out on the back...

toe-out on the rear wheels, will give oversteer when going around bends, if you have positive camber too though, this would reduce the effect...

get the alignment checked out..

Hey cant find the thing which had all about caster and camber etc but I just had a quick search and found this:

Caster, Camber And Toe

haven't read it yet but will do later, hope its of use to someone

[davexdavexdave]

i took all the weight out of my boot ie spare wheel and stuff and then turns out it does over steer and i hit the out side of a round about= goodbye mini lee. there goes 4-5k, a year of work and the car of my dreams. but i was being a fool and driving silly fast, however i had gone that fast before but with the spare and stuff in the boot so i blame taking that lot out lightening the rear. that and me being a prick and refusing to lose to a 106 needless to say i was faster but a litle too fast.

[icklemini]

have a few suspension jobs on at the moment, but drop me a PM if you would like to arrange a checkover / setup...

TTFN,
