Well i tried installing my blehmco big brake kit w/ 300zx calipers and the f!@#in calipers rubb on the wheel spokes. Now the question is should i upgrade to a 20 mm spacer to give me clearance or just get the 300zx rotor and have it milled down. The thing that troubles me is i dont know if running a 19 inch wheel with a heavier spacer and heavier rotor is going to be good for the wheel bearings, not to mention power loss. Is there anyone running the 300zx rotor who could give a review of the fittment. Sometimes i wonder why i even bother with this ***** F^^^in car.

 

why go to 20mm spacer? That might push out your wheels too much. Say your rims now are 40mm offset, a 20mm spacer would make it a 20mm offset rim.

measure how much space you need. I wouldn't recommend grinding down a caliper to clear your wheel. H&R does sell 5mm and 15mm spacers

 

Well the thing is i am running a 15 mm spacer up front already.

 

How much is it dragging? On my 17", I only needed a 5MM (H&R with new studs) on the stock hub to get my clearance. I "could" have ground off the word Nissan and it would have fit.

Changing rotor isnt going to help you...it not the OD of the rotor...but the depth of the caliper/bracket assembly from ground zero on the hub.

Good luck man!

 

Its just barely draggin. I think changing the rotor would help due to the fact it would move the caliper closer to the center of the wheel. This would help due to the way my wheel spokes are shaped. BTW how much clearance do you have now between your calipers and your wheel spoke.

 

you might want to consider new rims. Spoke design plays a big factor with rim offset

 

Larrio is right, spoke design is THE biggest factor in clearing 300ZX calipers. I've got both Konig Tantrum, 17x8 +40 offset, and Volk LE37T 18x8.5 +40 offset. I've got more clearance with the Konig's than the Volk's. No spacers on either set of wheels. Those spokes all the way to the lip on the Konig's makes all the difference in the world. Look at Matt's web page, that's my car that's shown with the kits and all three sets of wheels.

 

i was looking and if i go with a 20 mm spacer i am going to have at max 2mm of clearance between the spoke and caliper. Is there a minimum of clearance you want to have? Also would a 20 mm spacer be to much for the front wheels? Btw car is looking good.

Thanks

 

unfortunately changing the rotors will not make a difference. The caliper is sitting on the bracket, which doesn't move relative to what type of rotor you put on. Then consider the fact that unless your putting on a non-2k4 rotor, the offset and placement won't change either. change to a non-2k4 rotor and then you'll have to deal with offsets, hub clearance, and hubcentricity

20mm spacer would be extreme depending on your width and offset. I'm fairly sure you will rub, however I did drive with 17x9's with 35mm offset in the front without rubbing.

I have about 2-4mm clearance on my AP's with a 6mm spacer and 42mm offset 7.5 inch rim. But the AP's were designed to be spaced as far back as possible without rubbing. They clear stock 17 inch maxima rims with a 6mm spacer

 

IMO, I would never use a 20mm spacer no matter what. If it was my car, I would sell the Axis wheels and get some that will work with the 300ZX calipers(or any other BBK caliper), and be done with it. After having the kit on my car since January, you won't regret it for stopping power, and since your car leans toward show, looks also - epecially with Matt's rear brake kit that is on my car now too.
