Quick Question about brake clearance
 

If a set of wheels clears the Akebono's will it clear the brembos? Thanks

on a 350z or a 370z? reason i ask is a 370 does not have brembos so clearance would not matter. but on a 350 they should clear considering the akebono are bigger than the brembos. i have seen a 350z with akebonos fit LMGT-4 NISMO 18" wheels with no issues, also the 18" touring wheels

Nevermind. It was a dumb question. I was thinking they switched back to Brembo when they switched the color from grey to red. Im in Afghanistan and ordered a new 2014 Sport so i havent gotten to look at the car yet haha. So thanks man.

yeah you got Red akebonos. keep your head down and get back so you can enjoy it

Instead of starting a new thread, I though I'd piggy back onto this one (since the OP's question was answered).

My question has to do with break clearance as well. I understand that offset does not always guarantee Akebono clearance. I understand that it has to do with spoke design and etc.

What I was wondering - is there a measurement I can request from a shop or the manufacturer, that will help me check the clearance, without having to put the rim on.

I am not able to find a shop that sells the rims I was looking at, so they need to be ordered on line. It would be great if there was a way to measure if the wheels would fit without actually having a the wheel on hand.

Thank you. Sorry, not to arguing, but just trying to understand.

Isn't backspace the distance between the mounting plate and the inner lip of the wheel? That would only determine if the wheel will clear the suspension parts. Correct?

Wouldn't I want the measurement from the mounting plate to the inner edge of the spoke to see if the break will fit there? Or is the answer not that simple?

I guess I am trying to avoid the error part.

Ummmmmm... Cooltoy, tell us the wheels/size/offset/tire size!!! Then we can give you an easy yay or nay

Same as before.

I am good in the rear, but the fronts are making my decision difficult.

What my calculations show, is that as far as how far the wheels sticks out, my best option is:

20x9 +32 with 235/35 tires. (I am choosing between two wheels - Vossen CV2 or Rohana RC26)

However Vossen says that +32 will clear the brakes and Rohana says theirs will not.

My next option to go with +20 offset, which will definitely clear the brakes, but will stick out too far IMO.

Since I can not physically see the wheels, I was hoping I could confirm what each manufacturer says by having a measurement rather then just a verbal confirmation.


Thanks for helping.





.

There is also the issue of under steer you mentioned. Rohana is an 11" wheel in the back and the Vossen is 10.5".

i like the cv2's better. in fact, i was looking at a set to get my G until i decided to go with the gnosis.

what is your shop's return policy? id just buy the one front wheel with the ET32, and test fit. and if it fits correctly, then buy the other 3, get the wheels wrapped locally at a tire store that has a touchless mounter.

btw, if you're running stock height, no need to go 235/35, just get 245/35/20's.

i still think you're going to like the nismo wheels better though... those cv2, rohana, etc they are HEAVY for a sports car.

I know. I have considered all that. You'll probably lose respect for me, if I told you looks are more important to me. :eek::shakes head:

OK. That's fair, the sidewall on 245 on +32 will be flush with the outside of the fender.

I have been dealing with Jason at GETYOURWHEELS, I do not know what their policy is.

Jason is offering to shave 3 mm of the mounting plate to bring it to +23.

if so, you should go all the way and lower your ride. then you will have better wheel selection as the camber will work in your favor.

i can tell you that my ET33 19x9 running 245/40/19 still has some room to spare. it's tucked under the fender nicely, not sunken in and no poke.

the only thing that might not work out with your 20" is your sidewall thickness vs wheel gap. basic rule of thumb for dress up is for the wheel gap to be no more than 1/2 the height of the sidewall.

Wish I could, but I want to get the Amuse kit. I want to be able to get into the underground parking lot at work. Right now I have 1 3/4' to spare if I go in under an angle. I will loose 0.5' with the kit, that does not leave much lowering space.

oh i c... can you take your dd to work? you're not going to be driving your Z in the winter anyway, right? :confused:
this is your hobby car, you should make no compromise.

i dont take my Z to work either.

Its a dd in the summer and fall untill the first snow.

The measurement you are actually looking for (if I am not completely off base) Is the disk type. I know higher end companies will have different disk types for the same kind of wheel therefore allowing clearance for different brake sizes. With Vossen you should be able to simply call the manufacturer and ask about the offset and the car and they should have a chart with all of the measurements they can cross reference.

yah, some do note that in their description, but it's really the spoke design that determines whether it clears the caliper or not, so unless the manufacturer test fitted on the car it's hard to tell.

i see... that's a compromise then.

i would stick with your stock bumper, lower it, and get the CV2's. that would look better than amuse body kit, not lowered, and wheel gap. you have to commit to a style, can't just half arse it hoping it will look okay. especially since you are going for DRESSUP.

you bring a valid point there, i have seen wheels with the same offsets, same width/diameter but different spoke design where one would fit and another banged on the caliper. the new style sport rays are extremely close to the calipers, seriously measured in millimeters. unfortunately the only way to find out 100% is to put them on and see if they clear or not. if you really like the one that does not clear just get a 5mm spacer which will give just enough to clear a caliper but not mess with the body that much, if at all

I'd be ok with a spacer if I knew that 5 mm would be enough.

It's kind off funny, but to my eye coming of the Celica, the 370 wheel gap looks very small.

yah, the Z's gap in stock form (at least looking at the 19's) is even with the sidewall so it's not pronounced. as long as you run 19's with adequate sidewall height and conservative offsets, it would not look weird. :D

if you introduce 20's with shorter sidewall, then the gap will be more noticable even if you ran conservative offset.

especially when you introduce an agressive bumper like the amuse to the mix, you have to commit to that theme which will basically "require" you to lower your ride... otherwise your bumper/wheel will look out of place and your car's theme will be unfocused. would look better stock.

You could be right. I wil see how it goes. What's the least of a drop? Swifts?

As always your input and honesty is much appreciated.

i dont know about the least drop, but the swifts are a decent drop and appears to match the dampers very well.

i run swifts on my dd with stock dampers. for the first time these lowering springs actually matched the stock damp rate very well. no undulations, no floaty feel.

with other lowerings ive tried on various cars (eibach, neuspeed, h&r, tein, tanabe, etc) they dont match very well to the stock damp rates and required aftermarket adjustable dampers.

ofcourse you can always get koni yellows and set it up with your swifts for an even more refined ride to your preference, but for dressup probably not needed.

:tup:

There is a template you can use and forward to anyone to double-check clearance

Brembos are alot smaller size caliper than the Akebono so you want to be sure

Thats cool. Repped.
