Ideally yes, but a lot of people (including myself) dont have the level of skill required to drive a fast rwd car hastily in the wet.
I found rltc to be priceless on the supra tt, transformed the car for me and I think if I bought an mr2 turbo I would have to get it fitted, the '2 being even less forgiving.

the MR2 is setup for Understeer at slow speeds (and will quickly snap to OVERSTEER , ar$e swings round to meet the front) , to show you, get a safe bit of road (big desserted carpark, drive at around 5 to 10 mph , now try and do a shap left or right turn and floor it in 2nd or 1st and the car will plough on ahead like a FWD car, and will only regain grip when you let of the gass and then bite in the direction of turn that you wanted to go. the reason the car plows on straight is 1: supension setup and the 2nd is weight transfer, buy flooring it and turing the wheels from driving in a straight line you send all the weight to the rear of the car and the front is light, then you snap the throttle shut and the weight shifts now to the front henc you start to turn.

Now to get it to half spin , same again drive at 5 to 10 MPH then feint in the direction oppersit to where you want to go and floor it and at the same time turn in the direction you want to go, with the feint action you have shifted the weight and caused instablity and buy quickly turnign in the direction you want to go the car will now over steer and the rear will snap round. DONT GET SCARED at slow speeds and make sure you try this stuff in a safe spot .

To drive an MR2 quick and as safe as possible you must learn about weight transfer and how it affects grip at each corner.

Sorry to go on,

Next example is driving at 60 MPH on a netral acceration the car is stright and stable , you now start to break all the weight now shifts to the front of teh car and increases grip to the front tyres , when you release the brake the weight now shifts again to newtral (sort off) NOW important bit for MR2 in that senario , think that your goin into a roundabout , brake , brake and at the point you release the brake you start to turn right to go round the round about , a vast % of the weight is now on the left front wheel and the majority for the front and the rear left tyre has a little bit of weight (not much) and the rear right is nearly un laden , now if you tourch the throttle smoothly you now shift weight to a newtral balance and the car is under control, smoothley , if you are now still mid bend and you apply too much throttle the rear willl grip and strt to acclerate and then loose grip now at the LEFT rear wheel because the weight has now shifted to that wheel by you being to hard on the throttle , this over comes the tyres grip and the ar$e of the car start to slide, with a quick counter steer and corrective throttle the car will come back into line fine - but that takes experance of A. how much counter steer and B. how much or how littel throttle is needed to brign it into line.

The only way you learn this is to forcfully get the car to do it, but you need to under stand weight transfer which I hope from that pi$$ed up explanation you get the idea.

If there are any track days that we as a club can go on where all RWD-MID SHIP newbies can have some tuition from the Track day instructors it will make you a better driver.

But you need to stop beign scared of it slipping out , if you force it to slip out (at a track day ) you can learn how and why it does and again how much steering you need and throttle to bring it back inline.

Have fun and be safe.

Sorry for the ramble

Is this true, is the mr2 turbo, less forgiving (and by how much) than a supra? Is it just slightly less progressive in its breakaway due to the weight distribution?

(I currently have a TT supra and am considering a MR2 turbo as my next car, so just trying to find out what i may be letting myself into!)

I've had a supra and 2 mr2s and yes I would say that the '2 is quicker to brake away because of the weight distribution and the short wheel base. I may well be speakin out of my ar*e, but thats how I see it.

If you dont need rltc on your supe tt tho, you may be ok ? The thing is, I, personally, would get it anyway as the slip level is fully adjustable and there are always situations when its nice to have, ie torential rain.
