Ok so I got some weds kranze lxz wheels here are the specs

19x9.5 +38 front
19x10 + 38 rear

I have a problem with my front wheel not clearing the brakes which I thought about getting slightly longer wheel studs these to be exact

They measure 44.5 and stock is 44 which I believe is enough room to clear the brakes.

But here is my question I'm not sure on what mm spacer I should get for the front and the back I was thinking 5mm in the front and 10mm in the rear not looking to be too aggressive but just enough I'm not lowered at the moment plan on going lower but not slammed just looking for thoughts and opinions on everything thanks

 

They're only 0.5mm longer? That's basically nothing. You can usually run up to 5mm slip-ons with stock studs and have a safe amount of thread engagement. For 10mm in the rear you will need longer studs, absolutely. And not just 0.5mm longer, if 44mm is actually the stock length.
These ARP studs are 66mm http://www.enjukuracing.com/products...300-gs300.html

If you're not going to lower the car very much, while looks are subjective, aggressive fitment looks like *** without a stance to match, so personally I would recommend spacing them as little as needed. 5-8mm of spacing in the front would be a modest fit with no poke, and it would suit a moderately lowered car. In the front you could go 10-12mm further out, but it starts to look pretty goofy beyond that unless you have very little wheel gap and run some camber. In the rear, 10mm spacers (+28 effective offset) might require a trim to the fender lip, or a bit more camber.

 

5mm will work for a slip on, 8mm won't
