I found a member that is selling me their G/Z combo for my 2004 G35 sedan with sport suspension. I was then offered by another member that they had the SPC camber kit for the combo. My question is, is this kit really needed as the sport package comes with a negative camber set up for it to perform better from factory. Or is this for the G's with the stock suspension? I also have 235/50/17 (wider than the stock 215/55/17) tires on the sport 17" rims in the rear.

 

I have 2003 Z springs and 2007(?) coupe rears on my 2004 Sedan with sport (red) shocks. It was a perfect fit with no need for a camber kit (but it does "max out" the limits of the stock adjustability).

I'm running 19" Rays rims, with 245 40R19 tires on the back and I forget on the front). It's perfect. I wouldn't change a thing.

I usually drive my car short distances just a couple of times a week (I have a motorcycle, too). But for the past couple of months I have had a very long daily commute for a temp job out of town - logging about 1500 miles a month. I was worried the firmer ride wouldn't be as comfortable on regular long distances, but it's just as comfortable as the stock set-up (plus so, so much better for aggressive handling and a much nicer profile).

 

So before I use my G/Z spring combo I have 235/50/17 on all 4 corners. Will they rub with this combo? I'm a great DIY with cars done all my own mods but the tire part I can never get lol. Should I get spacers and what size? I'm going to also ask around to see. Thx ahead!

 

I don't know. I am sure you can look around the web to find the exact inflated diameters of each tire size. Mine rubs slightly in the rear if cornering when I have two adult passengers in the back seat. I almost never have anyone in the back but if it became more frequent I would roll the rear fenders.

As for spacers, my instinct is if you make the rear wider you are more likely to get rubbing.
