My car is going in next week to have one of the ball joints replaced due to a recurring creaking rear suspension. As this is suspension related and the S2000's settings seem are crucial to its handling should I insist anything is checked post replacement?

 

Maybe you can get them to check the suspension geometry settings following this work. See the Tech FAQ's for details of the optimum settings (opportunity for a free tweak?)

 

I agree - any suspension stripdown should be followed by an alignment check as a matter of course.

Especially since Honda will be paying..........
