I find the turn in a bit vague on these.

Wife has an M3 (benefits of working for yourself rather than like me lining somone else's pockets!). They compare quite well but you need bigger nads to get the best out of the BMW - 321 ponnies thorugh the rear wheels can be wild!!!!

Problem is I prefer driving mine except for this turn in issue. Anyone else find the same and know if you can fit something to sort it?

An idea of how much £££ would be good aswell.

I'm not a handling guru - but here goes.
My brother has an M3 and I have driven it back to back with my Subaru many times.
To get better turn in:
Powerstation bump steer mod - cheap highly effective
Change to 17" wheels - expensive and slight benefit
Flat floor set up - with geo changes - up to 200 quid depending on where you go, Powerstation will be able to do this as will most race teams - if you have a local one.
Suspension spring and damper change in conjuction with above - the dogs danglies but expensive.

VFM has got to go to the Bump steer mod.
Next - driver training? You can change the handling of the car a lot by a different driving style. Moving from a RWD car I found the Impreza to be an understeering monster - driver modification has cured that :-)

Anti roll bars rob grip from the end they are on, they are used to alter the handling balance - a stiffer anti roll bar at the front will induce understeer and reduce turn in

To increase turn in, in geo terms
Increase toe - even to toe out
Lower front ride height
Increase rear ride height
And of course if you have adjustable dampers theres even more to play with

That should keep you busy for a while, but relax the Scoob is a much better handling car than the M3

Davvers

forgot, you can play with tyre pressures as well - very cheap!

Not entirely correct Davvers.

While stronger ARB's can have the effect you describe, they also reduce bodyroll substantially allowing the angle of attack of the tyre to give better grip.

Best to fit in pairs. Anti Lift Kit will also reduce power-on understeer.

Davvers

true - but you would have to be getting a lot of body roll wouldn't you?
Come to think of it this may be what I'm suffering from, SDB thinks the dampers and springs you are running in your type R are a good combination. Care to let us know what you are running.

Edited as noticed you run scoobymania - if you would feel more comfortable emailing me that would great...if you don't mind!
