has anyone else noticed the setup page has gone from Johns website?? a bit disappointing........ There's always RaceTech I 'spose.

 

Yeah their site sucks now. A lot less information to be found.

 

Sounds like you have to talk to John if you do the mod yourself. I always have and found it worthwhile, anyway.

He lists a Utune-it program where you call him and discuss your needs, then he makes recommendations, and MAYBE parts. I'm not sure about what you get for the $99 fee for front and rear each. If springs and valve parts are included it's a great deal. If you have to pay extra for parts, maybe not so good.

My last set of springs I got from him were about $140.
