MacPherson strut does not [usually] handle camber changes very well and there is an issue with binding as the strut deflects under load. However, Porsche and BMW use struts, but if you look at them they are NOT simple MacPherson designs. They are also very well-designed units to limit the disadvantages listed.

An SLA is a multi-link which offers the advantages of a wishbone design, plus NVH advantages due to each link being separate and independent from the other.

Given a choice I'd like SLA on both corners.

Aside from a general hatred for Ford, suspension is one reason I have no desire to ever buy a mustang. It seems like no matter how you want to race one, through the twisties or down the 1/4, you are going to spend a TON of money before it handles or hooks up really well.

Anyways Chui is right, the main advantages in the MacPherson Strut suspension are not its handling characteristics, they are cost, ease of assembly, and compact design. They take up significantly less engine room area while offereing decentl suspension travel and ride quality/comfort (which is why manufacturers prefer them, especially for front wheel drive vehicles).

From a pure handling perspective a 4 link suspension is pretty much ideal as it can offer close to no chamber shange during body roll and cornering, and making sure the rubber meets teh road is what a good suspension is all about.

I'm staying general here because I haven't looked at a mustang's suspension very closely in a long time.
