It is very difficult to find a clean 2007 IS350 Sport w/ Nav... I plan on adding an IS-F steering damper, F-Sport Sways... would these options + some coils (not crazy low -_-) on a Lux package 350 feel practiclly the same as the 350 Sport package with its sport suspension..

I would also plan to do a trim wrap (aluminum) + add sport pedals however those are cosmetic, mostly concerned with the ride..

does this seem practical.. or should I continue to look for a clean 2007 350 sport package.. white or SGM

 

The only suspension difference between them is springs and shocks, so you could swap those over, or get coilovers with similar spring rates and be good.... ideally you'd find someone willing to swap interior trim with you 1:1... do those things and only stuff left would be sport pedals (since the scuff plates are better on lux IMHO)

I'd also say get an 08 if you can, steering feel is better unless you plan to swap an 11+ F-sport steering ECU (not terribly cheap).
