Depends on what ratio rack you put in it...

Can it handle well with a straight axle??? Depends on your definition of handling....It will go down the road straight, turn ok at reasonable speeds, and have a tolerable ride if the correct spring is installed...

Will it handle as well as an IFS in the windy-twisties at high speed???? No. But it's not fair to compare a design based on 1920's technology to a quality, well designed IFS.... Two entirely different concepts. With an IFS, caster and camber adjustments can be made easily, bump steer is a non-issue if the system is set up correctly, etc. Spring rates are easily changed, single and double adjustable shocks are available.

I'm not going to argue which is better, it's all dependent on your driving style...FOR ME, the IFS is the only way to go for the way I like to be able to drive a car.... Comparing IFS to a straight axle is not an apples to apples comparison.....
