i ordered the s-tune suspension and the stock spring arms look trashed. besides looking better, any reason to upgrade this part? anything to gain?

 

Nothing to gain except more height adjustability on normal springs.

 

toe adjustment too, correct?

 

Well there's already toe adjustment at that eccentric bolt, but if you needed more adjustment than what a SPL bolt gives then you typically aren't running a lower spring bucket anyways, you would usually be running true coilovers at that point.

Seems REALLY expensive considering what you're getting.

I used to have S-tune springs on the factory buckets and didn't have any issues just running the Z1 camber kit.

 

thank you sir

 

Should mention I also have the SPL toe bolts that give the extra +/- 1 degree of adjustment. I think I had to run... -1.5 degrees camber on the rear to get toe in spec.

I don't have any of those old alignment reports unfortunately.
