LCR Handling - Oversteer without lift-off
- Thread starter cuprajim
- Start date
I run 28psi in my tyres all round on the FR. Since having a full geo and new front tyres the other day I get plenty of lift off oversteer even with weight in the back.
I ould try lowering your rear pressures a bit, espeically if your not carrying much load in the boot. Other than that, just stay on the power to keep the rear planted

28 PSI is a very very low pressure to run your tyres at.I run 28psi in my tyres all round on the FR. Since having a full geo and new front tyres the other day I get plenty of lift off oversteer even with weight in the back.

Even a 1 tonne car has tyre pressures in excess of this and the LCR is 1,356 Kgs.
Keep tyres at 33 PSI or slightly above and you will notice an increase in handling characteristics.
But with an uprated front ARB you should really get the rear ARB done too to balance things out again.
Dunno what you mean??
The front end of most cars is the heaviest as this is where most cars have their engines.
Dunno what it is in the Leons but will be finding out when I fit Coilovers and get the car corner weighted

I found the rear end on my LC a bit loose in fast cornering.... my mk4 golf gti was the same but i get lot less understeer in my LC....
But now its lowered (50mm all round) ... its alot more planted.... the rear end only really comes out when i want it to...
but at the end of the day if your going around a corner that fast that your not confident in your car and it feels as though the arse end is gonna go.... then your going too fast(especially in current weather conditions) and it really aint worth smashing up your pride and joy!!

previously mentioned..." only having a front arb will contribute to the rear wanting to step out"
whats the rough price of a diff fitted if you did it at the same time as the clutch say??
yes i could search this but it's kinda on topic

a limited slip diff doesnt make you go round corners better though......it just helps you plant the power better in a a straight line...
£1k to £1,200 ish rough estimate fitted, think Jabba have some prices in their section
Peloquin and Quaife are the main Manufacturers
And it's not an LSD it's a ATB diff (automatic torque-bias diff)

This guy knows f00k all mate. Diff is MORE for handling , as when im on a roundabout and i plant it the diff will send most of the power to the outside wheel as this one needs to spin faster thus catapulting me round ...... If i planted my 300+ ponys with out this on a roundabout I WOULD DIE!!!! ALOT

lets set this straight...... a 'limited slip differential' DOES NOT help in the corners its helps you in a straight line..... when you floor it when you have an LSD ..... the diff locks so that equal power is sent to both wheels ... ergo the wheels are spinning at the SAME speed....
so when you are going round a roundabout..... the outside wheel needs to turn at a greater rate than the inside wheel as it is travelling a further distance than the inside wheel ( a regular differential allows this to happen as it allows the wheels to turn at different speeds to each other)
So with your LSD around a roundabout.... and you poot your foot down... the diff locks so that equal power is sent to both wheels.... so they are then spinning at the same rate/speed ..... this is bad because as explained above the inside wheel is spinning slower than the outside wheel... so when the diff locks the inside wheel spins the same speed as the outside wheel... so the inside wheel is now spinning too fast and your just burning up rubber with the inside wheel..... quite easy if you actually know whast your talking about... not just think you know what your on about just cuz youve watched the fast and the furious

Fast and furious, if im not mistaken, at no point makes any reference to limited slip differentials.
The majority of those who replied in aswer to your first statement, happen to be running these fancy diffs on there cars, so have experienced the effects.
I have also experienced the effects and can say that a car with the same setup as mine, but with a fancy diff, raped me front back and sideways.
i don't know much but the focus RS has an ATB LSD and this goes around top gear's track quicker than an R32, as i understand it it's one of the best handling FWD car's going??? i'm keen to hear a deffinative answer here????
Just a few bullet points ive taken from a dissertation i have done..... This is the basic principles of the 3 types of Limited slip differential.....
These numbers refer to the operation of the Limited slip differential.
A 1 way LSD only locks when the car is accelerating, which helps to keep the car stable under acceleration.
A 2 way LSD locks equally during acceleration and braking which additionally helps to keep the car stable and balanced under braking, although can require a little extra driver skill to avoid understeer in corners by unlocking the LSD
A 1.5 way LSD gives full lock under acceleration and partial lock under braking, thereby helping to keep the car more stable in braking, but without understeer

Suggest that you ALL have a read on the manufacturers site, rather than imagining what it really does

ATB and LSD diffs are different things.
Automatic Torque Baising - Helps round corners / roundabouts etc by sending the power to the wheel with the most grip.
Limited Slip Diff - Helps in a straight line by locking meaning that the 2 front wheels turn at the same speed and power is not lost due to a single wheel loosing traction.
someone correct me if i'm wrong
