Shorter ball joint for SPC upper control arms
 

Had anyone changed the ball joints that come on the spc arms for shorter ones? They are so much taller than the ones on the stock upper control arm and it hits on hard bumps/dips.

i think this has been an issue for a couple years now. its why everyone was waiting so patiently for SPL to make a set.

Ouch they are not cheap, had anyone had clearance issues with them?

with the SPL ones? no

with the SPC ones? yes

Damn how low are you?

To me not that low, these cars just have weird front suspension

I'm waiting on my coils to come in I don't plan on slamming it though. Maybe an inch but nothing more till I can save for the spl arms.

I think you're lower then letting on. Whats the ground to fender height?

are you guys talking about the thump on the front arms when hitting a dip ?

25.5" in the front

Yeah

Yes, which can damage your spindles and lead to catastrophic failure.

So you are 2.49 in lower than stock which is fuggin low! That's why, if your on coils, Just stiffen up the compression or raise the car up and get bigger wheels. To be that low the risk vs gain is very high for these nice cars. I would rather be safe and not "oh hella flush" than break stuff and loose the car and possibly myself or my wife. You can still look good and be safe and not jack up stuff. But it's you're car, just don't make a thread saying "crashed my z because pos spc arms were faulty".

For everyone that was wondering, my buddy made me some custom arms for max clearance, these will never hit.

Can you get him to give you the manufacturer, model and size information for the spherical/balljoint he used?

Yeah no problem

Nice. Simple, ams/kinetixs copy, so I'm sure it works. But no caster. Hope your left and right are close to equal.

Yeah they are exactly the same. I kept my spcs in the neutral caster position anyway so I didn't need anything special. These also have more than enough positive and negative adjustment which is cool. I read the kinetix arms were limited.

Mine are all the way in and the best i can manage is around -2.6 degrees, if I'm pretty low.

Which I am not, normally..

What did he charge you for them?

I have been tossing around the idea of having some just like yours made but with adjustable ends on the body-side too so that I can use sphericals there and use spacers for caster adjustment.

That's cool. Most just cut the nut down or threaded part so the tie rod end goes in more for more adjustment. I need caster since I'm 0.3* off.

I just installed a set of spcs(couldn't pass up the price) Im on swifts and koni, the left arms hits quite a bit, only had the right do it once...I did not want to shell out for spl, but looks like its gonna happen...sigh.

How do you like the Koni and swifts? I was thinking of going to that myself... Or should I just save for coils...

Its a really good street setup, IMO. I have also learned you can easily turn them into coilovers as well, koni sells a sleeve for the front and another company sells a kit you bolt into the bucket. Then you can run whatever springs you like! I will be doing this in the future for sure, the swift spec r are great springs, but I like linear springs better.

please elaborate my good man, I either need to stiffen up my springs or change out these arms. Is anyone here on kinetic arms? I also have spc which thumps like crazy at my ride height

Shameless plug
