And your last corsa a V6 yeah? Probably be much and such the same. I'm assuming the V6 weights a bit more than the XE, but do tigras not handle worse in standard form than a corsa?

Get proper tyres and stiffen the front, and run slightly higher pressures in the front, mostly.
If your weight distribution is all wrong (most stripped out front engine cars) then you'll never remove the steppy tendency completely but you can manage it with a bit of setup.

Then my guess is that unless you fit a RARB the tigra will be worse than the corsa.

I wouldn't run a c20xe corsa/tigra with FKs on, never mind track it!
If you don't wana change suspension then get some good tyres (Hankook RS2 etc), adjust front struts for more camber then make sure the toe is correct, might be worth getting some 300lb springs too they're £15 each

Stiffening the rear will make it more likely to oversteer.

Yes, massive improvement, I was shocked at the difference one bit of metal made

Rear ARB should introduce a contribution to the turn from the rear, if you want to reduce oversteer, this isn't the route to go!

Ian - a rear ARB dramatically reduces oversteer... Or am I missing the point

Rear ARB on a FWD reduces understeer

im shocked nobody has mentioned the rear brake compensater...... my xe corsa lowered -70mm was a mess a utter mess at therear until i modified it at work to release the springs further it made my back end un-prodictable and dangerous to say the least.....
as mentioned before though ive recently changed all the steering components and brand new bilsteins with 3 strut braces and poly bushes im only running middle class tyres and the transformation of the car is umbelievable.....

Theoretically the opposite is true as you've reduced independence for the inside rear wheel.
Ideally the ARB only tunes the shocks though, the tendency will be decided by the dampers.

Good point, I assumed everyone running one would have addressed this!
Goes without saying that your brake bias should be appropriate.

At that height you'll probably never get it right, there's only so much adjustment.
Basically it needs to be where it would be were the car to be standard ride height and unloaded.

True. I guess just taking the little spring out and chopping it in half would help ALOT...

I left mine loose instead or adjusting it, made a big difference, no more back end kicking out under heavy braking

A tutorial for setting up/adjusting the brake bias valve would be useful

Do bear in mind brake bias is not really a handling issue.
You could have a car that handles well and if you go barrelling to in a bend and rag the handbrake up, I defy you to get round cleanly
