17 or 18" wheel on rear of '17 ZL1 - Page 2

wanab · 09-05-2017, 03:50 PM

I bought in March with delivery in May. Not a lot of info when I ordered but I will add these. Have run a best of 11.339 @ 124.96 (3100 DA) with the tires and wheels you see and a Roto-Fab dry CAI. Wheels are Weld 77HB7095N67A (5X120, 6.7 BS, 37mm 0ffset, High Pad) and tires are MT Street R 305/45R17.

Only mean to throw out another real world example. I have the MT Sportsman skinnies in the garage and the matching wheels for the front ordered.

Good luck.

I was thinking on getting the 15" conversion but I had real good luck with Street R's on my Hellcat with a 305/45/18 managed a 1.4 60ft

I'd like to bump this thread up and get some more people with 17s!

What’s the width and offset? I have a set of Racestars 17x10.5 with a 32 offset from my 5th gen wondering if they will fit my ZL1.

17" x 10.5" and I’m not sure about the offset.

if you hot lap with 17s the discs can expand and touch the rims. Cool down time prevents this mostly.

newchevyman · 06-04-2019, 07:13 PM

Weld S71 20x7 fronts and 17x10.5 rears. 17s fit fine in the rear.

cmeJATT · 06-04-2019, 08:45 PM

What’s the smallest regular size wheel you can fit upfront ?

17x7? What back spacing ? And tire size ?

I bought race star 17x9.5 +20 305/45/17 for the rear

how do these 17inch welds get balanced? Look like there is hardly any room between the caliper and rim.

I run Forgestar 18" with 305/40 Mickey Thompson's.

WHAT? If the rotor disk was expanding that much, it would be hitting the brake caliper. It is not an issue of the brake rotor clearing the wheel, it is the caliper.

I'm running a 17x10 Weld single beadlock setup on mine. My wheel/tire company used standard stick on balancing weights. They barely clear my calipers. One sheet of printer paper will fit between the weights and calipers but has some resistance to being pulled out

I don't have a picture available with the Welds on the car, sorry. I added a couple of pictures to explain the the custom built transmission sitting there next the the Welds. I had an issue, LOL
