Just thinking about this- other than MR2s, are there any other reasonably performance oriented RWD cars that use a MacPherson strut setup on the rear wheels?  I'm drawing a blank here.

Just about all models that have IRS.

In reply to bentwrench :

Have an example?  I think maybe we have a definition problem here, I'm talking about this, where the strut takes bending forces and bolts to the knuckle:

Not just any setup where the spring is around the shock in a coilover configuration.

Edit: better picture

In reply to ¯\_(ツ)_/¯ :

Agreed, a McStrut involves the strut acting as a suspension locating link.  Technically it doesn't even have to be a coilover assembly to be a McStrut, although separate springs / struts are rare. 

As an example, my BMW has McStruts up front, but the rear is just a coilover spring / shock that doesn't function as a locating link (the rear is basically a double A arm).

I've got one. Starion/Conquest.

The Boxster/Cayman. I guess makes sense in mid engined cars since they're basically FWD orientation plopped back there. I'll try and think of a more traditional FR car.

Didn't know about the Starion (look how flat that subframe/control arm combo is) or the Porsche with that sort of awesome long trailing link.  Neat!

In the boxster/cayman case think it's actually a cheapness thing (engine isn't sideways so there's plenty of space). The 911 has just as much (arguably more) going on back there and it's multi-link. If you want to see something super sketchy, look up the GT4 multilink conversion kit.

Yeah, they designed the orginal boxster to use the same knuckles on the rear to save money.

Yeah, the control arms are massively wide to help locate the hubs fore/aft like a trailing arm would, but it's all one piece.

Not unlike many fwd cars, only its a simple pivot instead of a ball joint and no need for turning clearance.

The early adoption by Lotus led to the name Chapman Struts

 

 

edit: Chapman Struts are not the same thing but very closely related

Technically no, as it uses the halfshaft as a suspension member, so a Chapman strut.  Elan has a Mac strut even though some people will argue it's a Chapman strut.

Fiero, but that depends on how you define "performance oriented".

No cars have Macpherson struts in the rear.  Macpherson struts are in the front.

In the rear they are called Chapman struts, after the guy who first did it.

Don't Boxsters have struts in the rear?

Chapman struts are distinctly different from a Macpherson strut.  A Macpherson has a lower control arm, a Chapman strut uses the axle shaft as a locating link.  So you can build either in the rear with RWD.  But in the rear of a FWD car, for example, it's a Macpherson strut as there's no driveshaft.

If you want to get that technical, the last cars made with Macpherson struts were Saturn S-series, as they were the last cars that had a TCA located by the stabilizer bar smiley
