Just picked up some nexen Sur4G's 275/40/18 all around. Need to upgrade my front upper control arms. I've been reading, a lot of people have been having issues with SPC and Z1 UCA's due to them rubbing against the strut tower. I think this issue is more-so for stancey boy cars.

Anyone run Z1's "race" Upper Control Arms on their track car?

Just get get SPL and be done!

I really can’t justify paying that much for upper control arms. I don’t need an extreme amount of camber. So the only benefit I see of the SPL is thicker build material

They are stronger, easier to adjust and stay put after adjusting. The are less than a set of tires and they will last you until you sale the car.

I gauge the cost, value and benefits of permanent parts such as this base on the cost of tires.

Benefit over what? Other upper arm options? SPL is the only one that isn't prone to breaking on the track.

If you just need the adjustability, then you can get just about any of them. But if you drive hard, you will want the SPL. Not worth the risk of a weaker one breaking on you.

I think OP drives hard.

SPC FUCA (the original version) slips under high load, alignment won’t hold unless you use a homemade solution to hold that nut in place. One OG member did that long time ago. Have to remove arms for adjustment, PITA for the alignment technician.

SPC XAxis FUCA....haven’t heard anybody uses it here, seems like SPC copied SPL design. Unsure about ease of adjustment.

There is a reason why we like the SPL's. That's because they work with no issues. And are the easiest to adjust.
