Changing my STs from progressive rate springs to linear up front.

Need a source to buy top caps for the front that will fit but don't want to get KW's top cap/camber plate combo since I already have Ireland Engineering's fixed camber plates.

The KWs have a 61mm inner diameter.

Not sure about outter diameter or if that spec even matters.

Next step is to find out if Ireland's camber plates can be used with linear top caps once I find some that will work.

 

Allow me to answer my own question:
Ireland Engineering. Had to have the top caps modified by a machine shop for application with 61mm inner diameter of KW's springs but that's the solution. Done.
