I hear you on the 19's, but I think for the price and strength the 18s are pretty good. In fact I don't find them any heavier than the stock 17's I had, plus with 245 or 255 tires you get some more rubber to the ground. Frankly I don't really care, I'm all about cruising not trying to make the car as fast as possible. Hence why I picked the eibach setup over 350z, hence why I stand behind the stock exhaust.

 

Yes Texan1, it is a bit more rough and slightly slower.

 

Sounds really good..!! Did u take the rev limiter off your G ?? Also, isn't V1 Stillen catback supposed to have same performance specs as V2 ?? V1 is just lounder right ???
