What would cause the front tires to be wearing on the inside? Do I need a front end alignment? Suggestions are helpful ill try to post pics of tires. Plus I only got like 5k miles on tires the backs are still like 90% there

Thanks

if you lowered your car....tire decrease faster....uneven...need an alignment...steering rack n pinon bad...etc...lots of factors....usually an alignment should help out

Yeah I lowered it. Before I did I didn't notice any wearage. But when I got the car 3 of the 4 tires belts were slipped(got rid of those shortly after) but the front end shakes a little when cruising around 70 and there's some clattering on the front end. I'm thinking the ball joints need to be changed? If they do I might as well do tie rod ends and go ahead with front end alightment and have a fresh new front end?

that'll help.

Being lowered does not increase tire wear. However, lowering the car requires an alignment afterward because you've changed the suspension geometry.

Wear on the one side or the other of the tires indicates your camber is off or you have worn out suspension components -- without seeing the tires it's hard to say whether the issue is camber (creates wear) or worn components (creates cupping).

In your case, I'd get it checked for both alignment and suspension wear. A good mechanic, if it's suspension components, will tell you to skip the alignment until you replace the worn parts. Lowering the car creates a need for an alignment, every time -- and it sounds like you did not do so when you installed the lowering springs/coilovers. Your other symptoms could be the result of misalignment, and it needs to be for all four wheels.

I agree. I'm finishing my turbo set up in a couple of days and I'm probably going to be looking into ball joints, tie rod ends, sway bar end links and bushings, and then front end alignment. Is there anything else I need for a new front end suspension?

Lowering creates negative camber.
With no allignment, negative camber will wear tires.
Therefore, lowering creates tire wear.
