The SPC arms are probably acceptable for street use.

Wow, glad I asked. I actually ran SPC front arms on my G37 for 3 years, Auto-X and track and had no issues with them. Are they made any different?

I was very curious about this when researching that not many people run front camber arms, even being slammed.

Is this what people run for front arms then?

No track use.

Just a few of us, they are kind of pricey because they are race grade and made in small quantities. SPL might be a little cheaper and their design looks pretty solid but I wouldn't expect them to market before September.

Well I'm glad I didn't pull the trigger on SPC front arms last week ....

About to order V3's and full front and rear Camber kits.

SPC don't suck but they are difficult to align, a good bump will knock the alignment off and the rubber bushings deteriorate pretty quick under heavy use..........OK they suck lol. I wouldn't approve them for track use but for z's with crazy offset wheels needing that camber they aren't bad. Its a shame that SPL is taking forever to release their uppers. The Doran arms work well since they also use a shim design that won't knock it off alignment but you don't have as much adjustment for front caster.

Its crazy reading and reading and reading, realizing that guys on here have been talking with SPL since 2009 about their final product, and its almost half way through 2013????? wtf???

Yea I was joking with my friend the other day that has a 370z and he was complaining about his SPC upper arms and how he has to align them often. I told him that by the time SPL releases their upper arms, Nissan will have released the 450z.

Can you get solid bushing for the SPC arms?

Not from them, you would have to make or adapt something to fit.

We are on the same design that we started with last year....they work.
Our environment is probably THE harshest place ...one could test any suspension product. Zero issues.
Strong , light weight, and durable.

Can I have a sponsorship from doran? Lol

What about the caster adjustment?

I think me and you might be the only ones on here that run the Doran arms. Like you said they're pricey but definitely worth the money.
