I'm learking around in lowering my AWD but don't want to void my warranty. I might consider buying springs at the stealership, besides the F-Sport springs at the dealership, do they have anything else?
What percentage of tire wear would you typically get when you put on springs when comparing to stock springs?

Also, how do you negotiate labor charges at the stealership?

 

Will the stock springs off of the 350/250 work?

 

i don't know about tire wear but the shocks do wear down. springs for 350/250 will work if you do a search u will witness a lot of people have already attempted this on AWD. if you want to keep warranty ur only option is f sport. if you do attempt this ur lookin at $600 for just labor not including the springs. it might be a lil higher depending on the dealership.
