Wheel selection help

I too remember those days. I don't want to be crazy obnoxious with chrome or anything, I just want it to be different being that I am powdercoating my suspension parts and want everything to match up or my OCD will go insane

 

So after copious amounts of research (if only I spent this much time putting more effort into my classes), I found that the Subaru legacy uses a 5-100 bolt pattern as well and these wheels will be ideal for me because they are a 17X7.5 with a 48mm offset Sparco Assetto Gara Red Painted
This will be paired with these tires
Pirelli P Zero Nero

Overall this should give me the look I am going for I think, now I just have to put in a couple weekends more of work to get them.

 

They are 19 pounds a piece so a little heavier than the stock wheels but shouldn't really make too much of a difference being that I already have the roof rack/cargo bin set up.

 

How much do you think it will affect my speedo? I've only ever had real gauges in my cars before so we would just adjust the cables to compensate the difference

 

Fair enough, My access port may be able to compensate the different with some computer witchery but I guess I will find out after I throw the new shoes on there.

 

Just ordered the sparco wheels in red along with the new tires. I was just wondering what the thread measurements are for the lug nuts. Everything I am finding seems to point to the M12x1.5 but I just want to be sure.

 

Well I finally got them in and the TPMS switched over yesterday. It's like a brand new car.
