Guide to Reducing Understeer

Reducing Understeer

Dramatically reduce understeer with the early turbos by increasing weight over the front axle. Simply remove the spare wheel lightening the rear of the car, and hey presto! more grip - It is a pain however should you have a puncture (!).

Hi,

Caveat: there is no way to recover from oversteer on a Calibra.

If the back breaks away, that's it. All you can do is steer into the skid and hope that tree is further away that it appears.

Actually, also, removing the spare tyre will not increase grip at the front, but will reduce grip at the rear, moving the balance toward a more neutral handling car.

also adjusting the damping rate of the shocks and softer/harder anti roll bars will allow you to tune the car, i have had the back end out on the car but on a koni kit not great but it meant that the achilles heel of vx was taken care of.

thats why the vx220 was left to lotus

Hi,

It most certainly is.

I have passed many motorcycles on the outside bend with screaming tyres driving my V6 (used to be my party piece), but that would be lethal without the extra weight in the trunk because without that extra weight, as soon as you lift the throttle to keep the front in check the rear would break away and you'd be in real trouble.

I would not hurl a calibra in corners kamikaze style, trying to pass bikers hanging off their 600cc supersports without at least 60Kg worth of ICE in the trunk. Preferably more.

I would *never* do it with anything other than the stock suspention. I've seen to many 'tuned' lowered cars skid and spin out trying to keep up with me (and on two occasions hit the guardrail tail-first) to know that it's a bad idea to tinker with the suspension if you don't have the equipment to measure what you're doing.

Yeah i have to say the stock suspension is pretty good.  I've had a few "incidents" with sharp corners and been surprised the car managed to hold onto the road as well as it did.

I must stop racing Golf GTi's

not strictly true....

you apply throttle and the car will pull itself straight

you can recover from liftoff oversteer in a calibra, theres a nice big island by me which is fun in the wet :) (in 2wd by the way)

exactly!!

the only time you ever get oversteer in a calibra is due to diesel spills or a bad driver who does not know where to apply power on corners (or when to release power)

hitting WOT on FWD oversteer is a age old technique to recover from lift off oversteer

if you kbnow what you are doing you would never loose the back end of the cally......you would just understeer into a kerb if you was just over the limit

you really have to prevoke it to get the backend out too, like really chucking it in way over the top style, normal fast driving you only get understeer.

I took my V6 to a track day once, our friend has a kit car and I often go along as we used to race against eachother in karts. I couldn't resist, chucked my helmet on and lit up the front tyres, half way round the second or third lap a sapphire cosworth come past me, so I nailed it and round the corners he couldn't get away, the straights were adifferent matter but then I was back on his exhaust into the next corner. this has been the same case with many different cars on roads and country lanes.

I've driven many cars fast and slow on race tracks and roads!!! This car is still the one that shocks me the most on standard suspension. Pottering about it leans alot, going round a corner fast it understeers, push it in a bit harsher and it gives you very controlable oversteer, when you feel the back go and mess your pants!!!....some how...it still stays under control!!!!!! Stunning car :o

i totally agree with brain here, hell i drive fast all the time even in our peugot 405 diesel and the one thing fast drivers know is that to stop losing control at any point whilst going around a carner, short or short is whilst aceelerating towards the corner, you took the foot off the pedal then when your about 1/2 way into the corner you apply the power again this allows the car to push itself around the corner and accelerate out of the corner thus maintaining the fast speed you wish to keep and mainitn the control.

but what i need to know is that since i will be heaviy modifiying my future 4x4 turbo, is , is it better to leave the suspenion alone since im always doing the above, or is there a certain limit i can go to without destroying the reliabliity of the control.

Hi ALL

have to agree with the comments on the V6, bizarrely, I can push mine fairly hard in the dry, but the body roll compared to my 8v is proper scary, it is so vague in feedback, I think someone somewhere got the calculations wrong badly!!
How can 2 cars, so similar, perform so differently, my 8v performs just like my bro's on the road, I've replaced nearly all the suspension parts, convinced something was w*nkered somewhere, but i just can't improve the way it handles, dispite having the car tracked, and checked on a jig, it still want's to break away more readily in left handers than rights.......

Very Wierd

koni adjustables all the way! the stance is a little odd(ie a*** up). poly bushes everywhere, they aren't as harsh as people make out.
never managed to get the back to step out, unless it was on purpose..... :) complete contrast to my old koni equiped redtop cav(not independant rear suspension), that was scary for oversteer! the calibra out corners my friends DC5 integra without breaking a sweat, ok so i get left standing like a st bernard with a slight limp when the straight bits of road appear but hey!
