Hey by any chance if some of you guys have a set of BC Racing BR type coilovers for the G35 coupe, could you help me out with taking a few minutes for some measurements.
I emailed BC Racing already, proved to be futile cuz out of the 2 possible answers the front desk guy could have given me, he was fckin wrong on both counts.

I figure it's easier to ask someone here who has the coils laying around in a box, instead of finding a garage to go raise my car up take wheels off and do measurements myself.

This is what I need, the front and rear shaft diameter, and also the front and rear spring diameters as well. Pictures here and thanks

 

really ? nobody ?

I pm'd some sponsors on here as well that should have these in stock

 

Lol I was asking a seller the same question...need it for cup kit fitment. I'll keep You posted as well.

Sub'd

 

What coilover is that in the pic?

 

no idea what coilover it is, I've msg'd a few sponsors that should have these coils literally on their shelves. But no replies as of yet.....

My car is in the paint shop right now, otherwise I'd have measured it already.

If all else fails I guess I could go bother the paint shop guys to give me a few hours with the car

 

So nobody has a set of BC racing coils laying around they could measure ?

 

fck this forum is disappointing sometimes......

I had to spend 5 hours today lifting my car up and measuring because no sponsor replied back with anything nor would anyone here help a brosef out.... but whatever, for anyone interested that may need this info for the future, and measurements are this here for BC Racing BR Type coilovers


SHAFTS 12.5




SPRINGS 88mm

 

Sorry no help... Are you getting custom springs for your BC's? What is this info for

 

Sorry, just saw this post today.

If youre going for an air cup suspension youll most likely be told to buy Swift 65mm id springs.

Your rear upper mount looks weird...

 

Yea it's for a cup kit that is right.... and I figured Swift springs would be the answer as well if this is an issue...

the upper mount I just took the rings off, they actually sit as in the picture below with the upper ring off actually to get the car a little bit lower. It's raised now because it's winter, but summer it's all the way to the lowest setting and it just barely makes the height I want it at, and thats WITH the shorter 180mm springs of theirs....
So thats' one of the reasons I kind of regret going with OEM style BC racing coils, they perform well no complaints there, but I should have went with true coilovers like Stance.... they could go super super low, and much easier to adjust height, you don't have to adjust spring and strut separately which isn't as easy as it should be.

 

lol i wouldve done it if i seen this in time. have a pair still in the box. dont have that electric measuring thing tho..glad u got it solved tho

 

^ good to know someone on this forum is willing to help with something pretty simple...

hopefully this info is useful to others in the future

 

Swift Springs for BC BR coilovers are as follows:

OEM:
10K Front: Z65-178-100
8K Rear: Z65-178-080
8K Rear 1" Shorter: Z65-152-080

My Setup:
12K Front: Z65-178-120
12K Rear 1" Shorter: Z65-152-120

Edit these springs can be found from $160-$200 a set of 4.

I would personally recommend 12k/12k or 12K/10K. It will give you that little extra you want when you're riding on these.

 

my cup suspension install on the same set of coils
