I would love to jack up an R53 and an R56 side by side and take useful pictures of each to compare the differences. Most automotive reviews gloss over the fundamental differences between cars - I'd never heard of "roll understeer" until I started reading those suspension walkarounds on Edmunds. Same with the breakdown of torque steer that Dr. O covered in another recent thread. Very interesting how the suspension geometry dictates much of the character of the car.
another thing glossed over is 'scrub radius'...like when you push the wheels out with lower offsets. I've noticed a tangible loss in handling when doing so on my STI. The front would slide quite easily vs. stock offset (peak speeds on the same turn captured on my GPS).
Interesting - I have GPS measured my car over my regular fav twisties and on ramps and I have more grip (read more speed) with my 38 offset wheels. Maybe pushing the wheels beyond a certain point causes the negative effect, wonder how far it is.
I know this is an old thread, but I just got the ability to post on here again, my account would immediately log me out in the past...now it works! Thanks Nate!
But, I am interested to hear more about this and how can we counter act the scrub radius when using wider wheels with lower offsets?
How does one take benefits of wider wheels without scrub? Wouldn't you have to change where the shocks and wheel wells are? Thanks.
