A buddy of mine owns an fd. He recently picked up a set of these brackets. He the type of guy that can throw money around.

Question Jun basically states that with mass camber settings and high spring rates. front upper arm mounts can shear off. Has any fd owner found this problem on or off the track??? http://www.junauto.co.jp/products/re.../index.html?en

 

 

More stupid wastes of money. I've never heard of a single case of this happening.

 

Doesn't look very sturdy either. What is that 1/8" cheap sheet metal... That doesn't look like it would reinforce much.

 

but have you looked at your upper control arm mounting points. think about it. you have a structure extending out of the chassis. that is mostly sheet metal. add some coilovers with a high kg rate. aggressive camber.

plus i'm asking if any true auto x or time attack guy who track the sh*t out of their car have had a problem.... no daily drivers.

 

so if you think those brackets are stupid what about....

I used to know the president of JUN. Very nice man.

Most people don't drive their cars hard enough to use that stuff.
Even then....these two products are NOT the best products offered by JUN.

They aren't necessary for the FD.
JUN's specialties lie in their engine parts, w/ an emphasis on Nissan.

 

Give me a break....I'm not some car show poseur here....I've never heard of a single case in the track community of this ever happening. And your description of the upper control arm mounting points makes me think you have never looked at an FD.

And yes, I think that rear sub-frame brace is probably another big waste of money.

 

I've never heard of a case where this has happened (shear)... I suspect that if it ever had Fritz would know having owned and tracked over 40 FDs, and he's never mentioned it to me anyway.

Now, if they reduced flex at the pickup points, that might be valuable, but again I don' think that's an issue w/ these cars.

 

I can't picture how stiff springs will increase stress on the upper arm's mounts.

 

sorry man i wasn't trying to bust your chops. just doing some research on parts you don't generally see. mostly because i can see what jun was trying to do.

 

jun states very little about their product.

"Handling and stability of brakes will rise because rigidity of front upper arm is improved by this bracket brace"

and they also state

"As for FD3S and S2000 of the front upper arm bracket, it warps in the front-back direction and welding peels off when you run sport in many time. So, we made brace that installation was possible easily by bolt on"
