Hence I need to know if its worth my while with a KE55, and what the differences, if any, are.

 

Its my daily and I don't want to spend a heap of time and dosh on it, so cheap, simple mods are the go. I know a lot of the KSev boys use Sigma LCAs and aside from rebushing its a pretty standard affair, and considering I had KSev gear in my front setup, bar the '55 top hats, Id beg a guess the '55 setups are different to '30s?

On page 1 Evan g said all ya need to do is get the sigma lca's n rebush them

Rebush them. There is 2 different bushes. one with a 12mm bore and one with a 14mm bore. Use the 12mm bore bush. The length of the bush itself needs to be cut down to KE bush length.

 

Fit the LCA with the Sigma balljoint. Replace balljoint would be preferable.

 

Get a wheel alignment!

 

Sigma LCA's have been documented to give a KE70 5deg of negative camber.

 

KE30/55 LCA's into a KE70 have been said to give 2.5deg of negative camber.

 

So all things being equal, a KE30/55 with Sigma LCA's shoule have around 2.5deg of negative camber.

Evan also mentioned using XT130 arms to get negative camber in a KE30-55 - this is incorrect as the XT130 arm is identical length to that of a KE30/55
