17mm hubs are a bit lighter...
I would imagine the Cen hubs from the matrix are a direct fit.. I got a set of Jammin buggy hubs on mine.. You will need to shim them to fit.. and drill out the drive pins.. hardware store had a 8mm washer and used some 8mm shims I had.. the front needs less shimming then the rear...
Only reason I went with Jammin is Ebay and 7.00 for all four..
I probly spent the rest on shims and a drill blank .......
oh well.
