steering and suspension Strut Bearing Indentification

Not sure who's 02 this is. What kind of strut bearing is installed here?

Car looks like Ian Powell's 74tii with M20.  Car is now on the West Coast.  Not sure about the strut bearings. Try searching for his build thread.

They're KMac.

+1 on KMac

I haven't necessarily seen glowing reviews on them, but they are the only option for adjustability with full size springs. You would have to go coilover to get more range of adjustment.

Jose--not exactly. One can use full-size springs with other adjustable camber plates, such as those with spherical metal bearings that are used for track applications, by using the stock spring hat adapted to or in place of the coilover upper hat. You just cannot get as much negative camber with the large spring as with the smaller "coilover" spring. My '69 came set up this way, then I changed it over to coilover. My understanding is that these "Stage 1" Kmac bushings (poly) are stiffer than the stock rubber ones, but less harsh than full metal-to metal spherical bearing plates. The KMacs I have seen allow both camber and caster adjustment, while some of the race plates are camber only (with more caster than stock, but fixed). I have no personal experience with the KMacs, though.--Fred

Good point, Fred. 

 

My opinion is not to do a spherical top with regular strut because of the harshness and limited adjustability.  Seems like you should either go coilover or just put on fixed plates with stock tops. 

 

Although I suppose that on a street car you could put in a rubber gasket between the spherical top/body and reduce harshness a tad. 

 

Looking that those strut tops more, I am rethinking K-Mac.  I sort of recall a different brand that had that onion top shape.  I've only ever remember the K-Mac's looking flat.
