Called SPL again. Same story. ''Give it a few months, very early next year''. He continued to say they had to do several revised sets to get them right for clearence issue for the retail market. He also claims there at the machine shop and it's hard to force them to do work. And that they had several out on some race cars even though not 100% perfect it was good enough for them.

I stated to him there's a big demand for them here and he was aware. They want them out. Sooooooo......... I have SPL everything else so I really want there front arms. My SPC are great though as long as the top nut is TQ to 150lbs. It has never slipped once but the top nut has started to strip.

The only ones that would be easy to switch back and forth IMO are the Doran arms which unfortunately aren't commercially available.

With all the copying going on out there, I'm really surprised someone hasn't reverse engineered the Doran arms from the pictures they have posted.

Cool thanks for the response!

I just realized SPL is right across from Uprev in Austin TX. When I was getting my tune I seen their building, but never even thought twice about it. I should pay them a visit and see if I could take a look at these arms they claim will be ready next year.

in the past, the spl's UCAs were known for that property/ability

"Edit"You post months ago that you like the look of their design,

Did you have version one or version two?

What are you talking about... I have been on SPC since the car came out... Kinetix is a brand I have not like for years... maybe your confusing me with someone else or my posts for spc brand and spl brand...

I am trying to post it you,said you don't like the way they look,
Everybody jumping on the bash Kinetix cambers arms do you guys know there was a version one and a version two which the two is out now so we will have to see if they are any better.

Here's a picture of the SPL front arms on the SFR Enterprises WC 370z. No shims in sight. Maybe they changed the design since then but I highly doubt it.

They make great stuff but the problem has always been cost
Doran arm? $1500
SPL arms? $800

I'm guessing on price but I'm probably not far off.

SPL will be good bit cheaper. $600 maybe.

Racing parts are expensive.. Don't want to race, get SPC or Kinetix, they're good enough.

$500-700 is where I'd expect the SPL arms to come in at. They look like cast aluminum versus machined billet like the Doran arms.

That looks like a lot of adjusting and with the possibility of on uneven lengths since you have to adjust both ends.

You could adjust caster that way I would think?
