rack and pinion converson

[pandrade]

after a few google pages of randome clicking i fould out this website from the ukrain every tab from engine to suspension had a little somthing i dident know

http://www.mk3ukr-supra.net/home.htm

found alot of its info helpfull but one thing cought my eye above all
he says that people would convert the mk3's rack and pinion to that one of an rx7 or a mustang, i would imagine the only reson for this is for better steering respone. on his suspenson tab at the bottom he cover this but what i would like to know is how much truth there is to this and how practical would this be?

any thoughts
