Ok so first order of business.
Purchased:
18x9" square OEM M3 rims and some used 255/40/18 Potenza RE760's to get me though this summer of fixing up the car.
The 18's will eventually become my winters once I refinish um and have them painted gunmetal. Tires were not really what I wanted but they'll do for this 1st year (have about 50% on um), then I'll decide on some new summer wheels and tires next year or if I have $ after the car is all finished up.
Total cost was under $500 including shipping. Being thrifty #feelsgoodman
Dug into the doors and found all HK speakers (sans the rear deck) but decided to go with some upgraded 6 1/2 midbass in both locations so I picked up some Polk Audio db 651s from Crutchfield.
Everything should be in Wednesday or so, will get it all in and also get some FLCA's and FCAB's ordered up too so that is squared away along with some other bits.
