2013 Z RPF1 's

post 14, any thoughts??


Just thought I'd make a thread about my new RPF1's if anyone's interested. I've seen an old post here when Mike tried to fit them and he decided against it. His were different offsets but I went with a 18x9.5 +45 front and 18x10.5 +15 rear. I know the rears will look almost perfect! But the fronts need a spacer. Mikes offset was +38 and his did fit with a 15mm spacer so I have a 15mm spacer and a 20mm spacer coming so we'll see what works best for an overall of +30 or +25.

What I'm super stoked about is weight!! Online I see the OEM 19's weight (not 100% sure about the 2013's) 23.2 front and 23.8 rear. My new wheels are 17.4 front and 19.05 rear says Enkie. Also, OEM tires are 29 front and 33 rear. My new tires just for DD and had some good reviews are Sumitomo HTR Z3's which in Tireracks shootout beat the Hancook V12's that seem popular around here. They are 27.84 front and 29.08 rear (my weight). I got 255/40 and 285/35. Just a tad wider and shorter than OEM but they were really cheap and again I just need DD's for the moment. Also because I got black wheels I went with Gorilla black lug nuts. They are a lot smaller so I should save weight there too. I'm also not putting my OEM tire sensors back so again more weight savings.

So total weight loss of unsprung weight should be about 32.5 lbs that I know of so far; 13.6 front and 18.9 rear not including sensors, lugs or new 15-20mm front spacers.

Now I did weigh the OEM rear wheel and tire (forget the front) and got 57.5 pounds. So online might be wrong. Either way I know ill lose over 20 pounds and that's key since most of the weight is on the rear wheels. I'm not one to believe 1 lbs of unsprung weight equals 20 lbs of sprung weight but here's to hoping for a 400 lbs diet

Ill post pics when the wheels get here but for now...

anyone know what the OEM weigh?



Almost there!
