Wouldn't that be camber? Are there two SPL versions? How do you adjust caster with these below? I see camber is adjusted by using the four bolts.

 

^^ That's a set of 350evo A-arms. There isn't a caster adjustment on those.

 

no, camber is leaning top of wheel inside to outside... caster is forward to back...

As Kurtis stated, the 350Evo you posted above have no caster adjustment (not many do).

 

So i am trying to lower my car a fair amount, and planning on running a pretty agressive fitment. I only drive on the street and sometimes get a lil canyon trip going but nothing major, never tracking...at all..ever. I want to maximize tire wear, minimize noise and have heard that the spc's both get noisy and slip because the adjustment bolt on top sits in a long notch allowing you to adjust to exactly where you wanna be but then if you hit a rough spot on the streets it might have a tendency to slip and shift along the length of the notch. Idk how the SPL or 350EVO are set up, but the Cusco's I guess prevent this because the adjustment is not a long notch in the A-arm but separately drilled holes where the bolt can be locked down preventing any movement. Do I understand this correctly? Again, I want the most reliable no nonsense setup for the street with no noise and best tire use. Between SPC, SPL, 350EVO and Cusco which would you guys say?

 

Cusco is only designed for added negative camber adjustment so that option is out. 350EVO is the most expensive and the new SPL V2 is designed very much around the 350EVO at a lower price point. The SPL V2 also has caster adjustment which is something to think about if your caster is currently not to your liking.

By aggressive fitment, are you reffereing to having low offsets and stretched tires? or do you just want flush fitment with normal/wide tires. There is a big difference and there is ABSOLUTELY no such thing as low offsets/stretched tires with maximizing tire life. You cant have everything so you need to get your wants/needs down before you make a decision.

You want to minimize noise, cut the SPC's out of your list. They tend to knock with the top of the chassis on big bumps or dips.

The 350EVO and SPL's are at the top of the price range, but they are also the highest quality product made for our cars.

 

How do you adjust caster on the SPL arms? And V2 is better than V1?

 

Caster is adjusted on the part of the parms nearest the chassis mounts. The V2 is a much better design than the V1 as it mimics the 350EVO.

 

Meaning the cone shaped ends? Wouldn't that be hard to adjust?

 

Is there any downfall of having an "out of specification" caster?

 

If your cross caster is out of spec, the car will pull one way and can not be fixed any other way.

 

What about being even on both sides? Any performance issues? After my alignment my G was at 9.22° on each side.

 

That's perfectly fine. Caster doesnt affect performance unless it's waaaay out. In california our freeways are crowned, more so than most so you want the cross caster to be around -0.3 to make up for that so the car will track straight.

If it's even and not pulling then that's perfect.

 

OK, so it's not necessary to buy an A-arm with a caster adjustment?

 

the majority don't have caster adjustment... its not mandatory or even "necessary" (unless you have a caster issue)...

 

Would the 350EVO arms be one of the best choices for me? My G just needs a little more positive camber...
