Question 5 Lug Brake Rotor Fitment Question

Anyone know what rotors are used for ther cr-z 5 lug conversion for the front of a ge8?

I have a cr-z front spindle pressed into my fit knuckle. I am running cr-z calipers. I didn't realize the cr-z rotors will not fit. The hat on the rotor is too deep and the rotor hits the caliper bracket.

Anyone know what rotors people are using with this setup?

You can see the rotors hitting the caliper

CR-Z Brakes - Rotors are incorrect and don't fit

You'll likely be needing the CR-Z knuckle as well. The CR-Z's hub is indeed taller than the GE8's dispite them sharing the same brake caliper and mounting bracket... excluding the 2016MY CR-Z which got larger rotors and calipers all four corners.

Brake caliper details linked below via Centric.

Rotor details linked below as well. You can see supporting evidence of the rotor's hat height there.

ZF1/ZF2 CR-Z

There may possibly be a slight variation in the knuckle that we may not be able to see without both the GE8 and ZF1/ZF2 CR-Z knuckle side by side.

Also according to one forum member who has done the CR-Z 5 lug and brake conversion here. https://www.fitfreak.net/forums/fit-...ml#post1460917[

1 - While the CRZ and Fit front knuckles look the same, the CRZ takes a larger heavier duty tie rod. Because I built the CRZ knuckles for this (new bearings) I didn't realize this till I was done and connecting the tie rods back up. After some research I found the 2010 Accord crosstour outer tie rods seem to work. They're within .025" of the length of the Fit tie rods. If I'd built the Fit knuckles with CRZ hubs, it wouldn't have been an issue.

2 - The CRZ only got the rear sway bar for some years. I didn't know this so I had to transfer the sway bar from the Fit to the CRZ trailing arm. Knowing what I know now I'd be more picky about what year CRZ I used.

This seems like such a natural idea, I'd convinced myself I'd run into problems that would make this fail but so far, everything seems to just work. The Fit and CRZ use completely different brake line routing so, I had to make some brackets and buy some custom length brake lines to make it all work. I could have made the brake lines myself but they wouldn't be DOT certified and technically illegal for road use. The lines are supposed to show up some time next week.

The CRZ front hubs are 5mm taller than the Fit hubs so, the track is pushed out 10 mm total.

On a side note. I took the cr-v brakes off my EK9 and the caliper brackets have the same bolt pattern as the fit/cr-z. I bolted everything on and it actually fit better than the cr-z rotor/caliper but still wont work as it also hits. This would most likely work on a cr-z which would be a bigger brake upgrade.

My issue here is I wanted to keep the factory fit suspension geometry in the front by keeping the fit knuckle but if I cannot find a rotor that works I will be forced to switch over to the cr-z knuckle.

I will still be looking for a rotor that fits but I picked up a 3mm wheel spacer and machined it to fit behind the rotor. Works perfect and puts the rotors right where they need to be.

CR-Z hubs and Fit hubs are the same height. It has to be the knuckle that gives the CR-Z the wider track.
