MX5 NC Upper Control Arms - Replacement Bushes
We recently published and article about building up an MX5 NC as a road car/track car for one of our customers in Melbourne. Part of this write-up included the replacement of the upper inner control arm bushes to the Whiteline offset pin kit. The benefit of this is it allows for extra camber to be dialled in.
Using a hacksaw we cut into the outer metal ring of the OEM pressed bush. Then lever up the edges and move them backwards and forwards to break off the tabs.
Then its just a matter of pushing in the new bushes. I like to use a vice as I find its easier to move the arm and centre the bush at the same time or use a press.
Push the metal offset pin into the arm and tap it home with a drift. Align it before it's pushed all the way home.
This will affect your wheel alignment so put that to the top of the to-do-list!! For those in Sydney the obvious choice is Spinning Wheel as what they don't know about MX5's wheel alignments isn't worth knowing!!
